Conjugation occurs by two, methods–, (i) Scalariform conjugation, It takes place during the night and, between the recently divided cells of, the conjugating participating, filaments. Opposite cells of two, filaments develop conjugation tube, by lying side by side and parallel to, each other. The conjugation tube, between two filament looks like a, ladder, through which gamete from, one gametangia passes through to, fuse with the passive gamete of, another filament., (ii) Lateral conjugation, Two adjacent cells of same filament, function as male and female cells. It is, commonly reported in S. affinis and, S. fenuissima., (d) Pteridophytes are seedless vascular plants., They are also called vascular cryptogams, as they possess xylem and phloem., (b) Largest ovule in plant kingdom is found in, Cycas. Female cone consists of, megasporophylls. Each megasporophyll, bears 2-12 reddish ovules in the middle, fertile part. Ovules of Cycas are the largest,, 6-7 cm in diameter., , The sperms of Cycas are also the largest, (300 µm) in the biological world., Coconut milk is rich in compounds, chemically similar to cytokinin and promote, callus growth by inducing cell division., Neottia grows on soil rich humus. It has, an underground stem with a cluster of roots., The roots are associated with endotrophic, mycorrhiza. The fungus absorbs its food, from humus and the cortical cells of the, roots of Neottia absorb food from humus., Neottia is actually a parasite on fungus., Bryophytes are terrestrial plants found in, moist places and shady localities .They are, rightly called the amphibians of the plant, kingdom .Since fertilization does not occur, without water. Being in moist places, water, and mineral salts are being absorbed by, rhizoids that have the main function of, fixing the plant. Absorption also occurs due, to diffusion. Moreover, these plants are, very small. Hence, Bryophytes do not, possess the vascular tissue., The heart shaped prothallus is the, characteristic feature of ferns and mainly, belong to polypodiaceae.They show, polarity and dorsoventrality. The, prothallus contains both the antheridia and, archegonia which are embedded in the, prothallus. Since it forms the male and, female gametes the prothallus is, considered as the gametophyte., When the capsule of the sporangium in, Dryopteris matures, about 4 lower median, cells of the jacket stretch tangentially. The, two median ones identify the place from, where the capsule opens. This is called as, stomium. The other cells of the jacket, develop a thickening . At maturity, the, indusium dries exposing the sorus. Due to, loss of water in the annulus, the upper walls, contract and inner ones straighten, the, annulus coils.

The 13 celled male gametophyte has, 12 antheridial cells and one prothallial cell, as a result of segmentation. This is to, increase the number of biflagellate, antherozoids., The algal zone consists of blue green algae, in the coralloid roots. The relationship is a, mutual relationship. The algae get the, dwelling place, while Cycas can use the, food produced by the algae., Sex organs in Funaria develop at the tip of, gametophore since the plant itself, constitutes the gametophytic phase. After, fertilization develops the capsule from, which protonema develops from the spores, that dehisces from the capsule. The capsule, constitutes the sporophytic phase. The, plant shows an alternation of generation,, between, the sporophytic and, gametophytic phase., The rachis and leaflet have diploxylic, vascular bundles. At the region of the stem, cortex, the leaf trace has only centrifugal, xylem, hence, it is endarch. These traces, enter the leaf as the rachis separates, the, centripetal xylem appears and it is in the, exarch condition. The leaflet has a single, midrib bundle and is in the diploxylic, condition., Funaria is both monoecious and, autoecious. The antheridium (male sex, organ) are born on different heads of the, same plant. Hence, it is both autoecious, and monoecious., Apogamy is the formation of sporophyte, from a gametophytic cell other than egg, without fertilization. The prothallus is only, a part of gametophytic cell. Hence, the, development is apogamy., The united protoplasmic mass of two, gametes is called zygote or zygospore. Prior, , B-15, , 17. (c), , 18.

Three of the four nuclei degenerate, since they are smaller in size. The last cell, is bigger and grows using the reserve food, substances., Cycas is dioecious in nature since it, produces micro and megaspores in the, micro and megasporangia. The micro and, megasporangia, are, born, on, microsporophyll and megasporophyll, respectively., Atropa bellandona produces the drug, belladona. It is an alkaloid which is atropine, and hyoscyamine. The leaves and root, contain the alkaloid. It is used to cure and, relieve pain., Algae is a collective term for all those, chlorophyll bearing organisms which are, thalloid. So, during photosynthesis by, taking in CO2 and giving out O2, they purify, the atmosphere., In the life cycle of Funaria, two distinct, individuals occur. One of these is haploid, and is independent leafy plant. The other, is diploid, leafless sporogonium. It is, partially dependent on the leafy, gametophyte for its nutrition., The diploid bispiral elaters are hygroscopic, and they help in the dispersal of spores., Megasporophyll of Cycas bears ovules, similar to carpel., Cyphella are aerating organs in the form of, organised breaks, which occur in the lower, cortex and appear as concave circular, depression where white medulla is exposed., , 24. (c) Ulothrix being an haploid organism, shows, zygotic meiosis. Zygote is the only diploid, structure which undergoes meiosis to form, four cells. Each develops into Ulothrix., 25.

Nymphaea, Sagittaria and, Vallisnaria are rooted hydrophytes while, Ceratophyllum is a submerged floating, hydrophyte. It remains completely under, water but is not rooted in mud., Ceratophyllum lacks roots even in, embryonic stage., 34. (b) Sporocarp is a reproductive structure of, some aquatic ferns like Marsilea., Sporocarps are functionally and, developmentally modified leaf which bears, several sori. Each sori consists of, sporangia of two types -megasporangia, producing simple large female megaspore, and microsporangia producing many small, male microspore., 35. (d) In Cycas, coralloid roots are bluish green, in colour and have blue-green algae in their, cortex. This character distinguishes them, from angiosperms., 36. (b) Number of chromosome in root cells of, wheat plant is, 2n = 42, n=, , 42, = 21, 2, , The number of chromosome in the cell of, pollen grain is 21 because pollen grains are, haploid (n) in nature., 37.

B-26, , 45. (a) Nephridia are invertebrate organs which, function similarly to kidneys. They remove, metabolic wastes from an animal’s body., They are of two basic types, metanephridia, and protonephridia. A metanephridium is a, type of excretory gland or nephridium found, in annelids, arthropods and molluscs. A, protonephridium is a network of dead-end, tubules lacking internal openings. The ends, are called flame cells or solenocytes; they, functions in osmoregulation., 46. (a) Morphallaxis refers to the type of, regeneration in which lost body parts are, replaced by the remodeling of the remaining, tissue. In this type of regeneration, little or, no cellular proliferation takes place during, the regeneration process. A classic example, of an organism that regenerates using this, mechanism is the Hydra. When a Hydra is, cut into two pieces, two Hydra as will be, regenerated, both smaller than the parental, Hydra. Once regeneration is completed, the, two Hydra can continue to grow and reach, the size of their original parent. Growth, requires cellular proliferation but during the, regenerative process very little cellular, proliferation takes place., 47.

Hence, it, is also called 'Mitotic Poison'., , 3., , 4., , 5., , 6., , (a) Spindle fibres of mitotic cells are made up, of microtubules. It consists of protein, tubulin that maintain cell shape, serve a, tracks for organelle movement & help in, cell division by getting attached to the, centromeres of bivalents. They are, arranged on equator due to congression, movements. The movement of bivalents or, chromosomes occur towards the poles as, a result of spindle fibres contraction., (b) Synapse stabilizes the paired condition of, chromosomes in zygotene stage. After this, the cell enters the pachytene stage., (a) In most eukaryotes, the nuclear envelope, that separates the DNA from the cytoplasm, disassembles. The chromosomes align, themselves in a line spanning the cell., Microtubules, essentially miniature strings,, pulls out from opposite ends of the cell, and shorten, pulling apart the sister, chromatids of each chromosome. As a, matter of convention, each sister chromatid, is now considered a chromosome, so they, are renamed to sister chromosomes. As the, cell elongates, corresponding sister, chromosomes are pulled toward opposite, ends. A new nuclear envelope forms, around the separated sister chromosomes., (d) In bivalent formation of chromosomes, durin g meiosis, the homologous, chromosomes are arranged in pairs. The, , 7., , 8., , phenomenon is called synapsis and it, occurs durin g zygotene stage. DNA, replication occurs during S phase or, synthetic phase which is the second phase, of interphase., (d) Many cells function properly and, divide mitotically even in the absence of, plastids., (d), , 9., , (b) During zygotene, a substage of Prophase I, of meiosis I, where chromosomes start, pairing together is called synapsis. Such, paired chromosomes are called as, homologous chromosomes. A complex, structure i.e., synaptonemal complex is, formed by a pair of synapsed homologous, chromosomes called a bivalent or a tetrad., 10. (a) In mitosis, a single cell divides to form two, daughter cells. So, the number of mitotic, divisions can be calculated by 2n., where, n is the number of division of cell., 2n = 128, 2n = 27, n=7, Thus, 7 mitotic divisions are needed for a, single cell to make 128 cells., 11. (c) A – IV; B – III; C – II; D – I, Metaphase – Chromosomes are moved, to spindle fibre., Anaphase – Centromere splits an d, chromatids move apart., Zygotene – Pairing between, homologous chromosomes, takes place., Pachytene – Crossing between, homologous, chromosomes occurs.

It ensures, the maintenance of constant number of, chromosomes from generation to, generation on a species., (c) Previously interphase is called resting stage, because there is no apparent activity, related to cell division. The interphase cell, is metabolically quite active. Interphase, consist of three subphases (G1 , G2 and S)., Synthesis of DNA occurs in S phase. G1 is, the period between the end of mitosis and, the start of S phase. G2 is the phase, between S phase and the next mitosis. As, the synthesis of DNA and proteins occurs, in interphase so, it is considered as, metabolically active phase., , 15. (b) During zygotene, because of the pairing of, the homologues, the nucleus contains half, the number of chromosomes. Each unit is a, bivalent composed of two homologous, chromosomes., 16. (d), , 17. (b), , Interkinesis or interphase II is a period of, rest that cells of some species enter during, meiosis, between meiosis I and meiosis II., No DNA replication occurs during, interkinesis however it does occur during, the interphase I stage of meiosis., Interkinesis is generally short lived., Diplotene is the longest and most active, subphase of prophase I of meiosis. The, beginning of diplotene is recognized by, the dissolution of synaptonemal complex, and the tendency of the recombined, homologous chromosomes of the, bivalents to separate from each other, except at the sites of crossovers. These, X-shaped structures are called chiasmata., Diplotene can last for months and years in, oocytes of some vertebrate., , EBD_7100, , IIT JEE NEET eBooks: www.crackjee.xyz

(c) Imbibition is the process of adsorption of, water by hydrophilic surfaces of a, substance without forming a solution. It is, a type of diffusion by which movement of, water takes place along a diffusion gradient., The solid particles which adsorb water or, any other liquid are called Imbibants. The, liquid which is imbibed is known as, Imbibate. Examples are absorption of water, by seeds and dry wood., 11. (a) Potassium is accumulated by passive, transport. Some solutes are pumped across, membranes using active transport. The role, of proton pumps in the transport process, of plant cells is a specific application of, chemiosmosis, a transmembrane proton, gradient that links energy-releasing, processes to energy-consuming ones like, active transport., 12. (d) The casparian strips function in regulation, of the flow of water between outer tissues, and the vascular cylinder., 13. (c) DPD = OP – TP., DPD (A) = 4 bar., DPD (B) = 0 bar., DPD (C) = 10 – 5 = 5 bars., DPD (D) = 7 – 3 = 4 bars., Water always flows from lower DPD, (Diffusion Pressure Deficit) to higher DPD., Since the DPD of cell B is the lowest (O) the, water will flow from B to A and then to C., 14. (c) Active transport uses energy (ATP) to, pump molecules against a concentration, gradient. Cells undergoing active transport, bear abundant mitochondria to provide, ATP, needed to power active transport. So,, the production of ATP is blocked or, decreased and active transport is blocked, or slow down., 15. (c) Statements (iv) and (v) are not correct., , Active transport is the mediated transport, of biochemicals, and other atomic/, molecular substances, across membranes., Unlike passive transport, this process, requires chemical energy in the form of, adenosine triphosphate(ATP). In this form, of transport, molecules move against either, an electrical or concentration gradient, (collectively termed an electrochemical, gradient)., Phloem is the chief food conducting tissue, of vascular plan ts responsible for, translocation of organic solutes., In rainy season, door gets swelled due to, the phenomenon of imbibition. It is the, process of absorption of water without, forming a solution., Upward movement of water (sap) through, xylem against the force of gravity is called, ascent of sap. All three help in ascent of, sap., Cultivation of plants by placing the roots, in the nutrient solution without any soil is, called hydroponics. It is also known as, soilless culture/ water culture/ solution, culture. It is used to determine which, elements are essential for plant growth and, what symptoms are produced by the, absence or deficiency of essential elements., During sodium-potassium pump, the, concentration of sodium ions will be about, 14 times more in extra cellular fluid (outside), and concentration of potassium ions will, be about 28-30 times more in axoplasm, (inside). Thus, 3Na+ and 2K+ are transported, during the process., Excessive loss of water from the leaves can, be prevented by applying vaseline on leaf, surface. It will close the stomata and check, transpiration., , (c)

This adaptive feature is seen, in xerophytic and in plants of semi-arid, region. This adaptive feature is seen to, reduce water loss by transpiration., (a) The radial and the inner walls of the cells, of the endodermis are greatly thickened., These are called as casparian strips and, these are impervious to water. Apart from, the casparian strips, and suberization also, does not allow the water to reach the, endodermis. Hence, water moves through, the apoplast which are passage cells., (d) Root pressure is a pressure produced in, the roots of plants, causing exudation of, , sap from cut stems and guttation of water, from leaves. The pressure is generated by, the concentration of solutes in the xylem, of the root and stem which is then causes, water to move into the xylem by osmosis., 19. (c) Sap is water with dissolved ingredients., The upward movement of water from roots, towards the tips of stem branches and their, leaves is called ascent of sap. It occurs, through the tracheary elements of xylem., 20. (a) The parietal cytoplasm and perforated, sieve plates help in the transport of, photoassimilates that are required for, photosynthesis. The parietal cytoplasm is, the streaming of cytoplasm. The streaming, cytoplasm moves throughout the cell, thus,, helping in the transport of photoassimilates, from one cell to another through the sieve, plates., 21. (a) Light is an important factor in transpiration., The stomata opens well on days when light, is brighter. It is also evident on cloudy days, that the stomata does not open well.

It also activates, other pancreatic proteases., 32. (d) It is not lipases but the bile salts which are, responsible for the emulsification of fats., Bile salts are steroids secreted by the liver, in the bile. In the intestinal lumen, they, reduce the surface tension of fat dropletes,, causing their breakdown into many smaller, ones. A stable fine emulsion of fat is thereby, formed. On the other hand, lipases are the, enzymes which hydrolyse fats and oils., Lipases can digest fat in significant amounts, only when large fat droplets are broken into, tiny droplets to form a fine emulsion., Emulsificaion of fats by bile salts thus,, increases the lipase action on fats., 33. (a) In the condition of obstructive jaundice the, entry of bile into the small intestine is, prevented due to an obstruction in the bile, duct. As we know that bile salts help in the, digestion of fats by emulsification and also, in their absorption by the formation of, water soluble droplets called micelles from, whom fatty acids, glycerides, sterols and, fat soluble vitamins are absorbed into the, intestinal cells.

Later, on fibrin entangles corpuscles to form a, clot. Thrombin is not mormally found in, circulating blood, but instead it is repressed, by its inactive precursor prothrombin. The, conversion of prothrombin to thrombin, requires blood platelets, calcium ions and, thromboplastin., (c) Blood group ‘O’ is universal donor. Group, ‘O’ blood, with no antigens, can be given, to anyone., (b) Left ventricle of the heart has the thickest, wall because it has to pump the blood to, the farthest end of the body., (b) Malleus is hammer shaped; lymphocytes, are type of leucocytes and hemophilia is, bleeder’s disease (genetic) disorder). SA, node acts as pacemaker because it, functions as originator of cardiac impulse., (c) Artificial pace maker is implanted to the, patients where heart beat level drops, abnormally low (30-40) due to disease or, operations., (b) In this figure, coronary angioplasty is being, done where atherosclerotic plaque, which, builds up and clogs the coronary arteries,, is compressed against the vessel wall by, expanding a balloon like device inserted, through a catheter that has been threaded, through the artery., (c) Hirudin is an anticlotting agent produced, by transgenic Brassica napus., (d) Blood contains an anticoagulant called, heparin, which prevents the activation of, prothrombin. The latter is an inactive, globulin which is required during blood, coagulation. Heparin is released from the, mast-cell granules., (a) High proportion of cholesterol in blood, leads to deposition of cholesterol on the, , 11., , (a), , 12. (d), , 13. (c), , 14. (b), , 15. (d), , walls of blood vessels. This causes the, arteries to lose their elasticity and get, stiffened. This is called arteriosclerosis or, hardening of arteries., Lubb sound is caused partly by the closure, of the bicuspid and tricuspid valves and, partly by the contraction of the muscles in, the ventricles. Lubb is the first heart sound., The lymphatic system not only regulates, fluid amounts in the blood but also helps, to fight infection. The lymph nodes, produce white blood cells and filter harmful, bacteria, that is why they tend to enlarge, when we have an infection., Coronary arteries supply the blood to the, heart. Carotid arteries supply the blood to, head region. Hepatic arteries supply the, blood to liver while the pulmonary artery, supplies blood to the lungs., Accordin g to ABO system of blood, grouping, O type blood can be given to, person of all types of blood, i.e., O, A, B, and AB. Hence, a person with O type blood, is called universal donor., Accordin g to Rh system of blood, grouping, most of the people have blood, in which there is a substance called Rh, factor. Rh stands for rhesus. This type of, blood can be donated only in rarest of rare, chances. In India, about 97% of people are, Rh+. So, if an Rh+ person is transfused with, Rh+ blood, then it is safe. But if an Rh, negative (Rh–) person is transfused with, Rh+ blood then he/she will develop antiRh factor i.e., antibodies in his/her blood,, and there might beno harm is, but may kill, the recipient if a second Rh + transfusion is, done., The number of blood platelets per cubic, mm in human blood is 3 lacs while the, number of WBCs are 5000/cubic mm of, blood. Veins are as complex as the arteries., Veins and arteries both are types of blood, vessels. Arteries carry blood from heart to, different organs while vein carries blood, from different organs to heart. At any given

(d), , 21., 22., , time in a healthy human, the blood amount, is same in both, as the circulation of blood, never stops., Blood consists of two parts:, The plasma (water, proteins, inorganic salts, and other elements) constitutes 55-60% of, blood while cellular part constitutes 4045% of total blood. WBCs are produced in, red bone marrow, lymph nodes and, sometimes even in liver and spleen., Spleen is referred to as a blood bank of the, body because it is the organ having the, function of making and storing, lymphocytes and red corpuscles. These are, squeezed out into the blood-stream when, the body needs more in circulation, as for, instance in haemorrhage or shock., Fasting glucose level is 70-110 mg/decilitre., Total blood volume in normal adult human, is 5-6 litres. Blood is a fluid connective, tissues. Its cells consists of corpuscles., Plasma represents matrix of blood. Blood, is mesodermal in origin and salty in taste., Its pH is 7.3 – 7.4., 19. (c), The P-wave represents the electrical excitation (or depolarisation) of the atria, which, leads to the contraction of both the atria., The QRS complex represents the, depolarisation of the ventricles, which initiates the ventricular contraction. The contraction starts shortly after Q and marks, the beginning of the systole., , (c), (c), , Type B : Assertion Reason Questions, 23., , (e) The sinoatrial or sinoauricular node, determines the rate of heart beat by, determining the rate of discharge of cardiac, impulse. It is called the pace maker. It is, formed of specialized cardiac muscles and, is located in the right atrial wall near the, opening of superior venacava. These, muscles are self excitable. Since it is self, excitable, it can produce waves at highest, rate. Hence, the assertion is incorrect., , 24. (c) Saline water increases the blood pressure, due to the presence of NaCl in it. Hence,, the reason for the assertion is false., 25. (b) Blood pressure is the arterial pressure of, blood exerted on the wall of arteries with, each heart beat. It is measured form the, brachial artery in the elbow pit. It is, expressed as, , 26. (b), , 27. (a), , 28. (d), , 29. (b), , systolic pressure (mm/Hg), diastolic pressure (mm/Hg), Arterial (superficial; arteries) blood, pressure, is, measured, by, sphygmomanometer., WBC’s are wandering cells capable of, coming out of blood capillar ies by, amoeboid movement called diapedesis., Haemophilia is caused by lack of activity, of blood clotting factor VIII or IX and they, show platelet function disorder., When an injury is caused to a blood vessel,, bleeding starts which is stopped by blood, clotting. At the site of injury blood platelets, release platelet factor - 3 and injured tissues, release thromboplastin. The two combine, to form prothrombinase enzyme which, converts prothrombin to thrombin. The, latter stimulates formation of fibrin thread, or clot. Blood contains an anticoagutant, heparin which prevents blood clotting in, uninjured vessels., The basal metabatic rate is defined as the, energy requirement of human body at rest., BMR of smallest animals are generally, higher then larger animals. Peoples with, higher metabolism means that they have, higher heart rate. Heart rate of baby is, 70-190 times/minute, whereas adults, (including serious) is 60-100 times/ minute., , 30. (b) Prothrombinase enzyme is necessary for, blood clotting. It acts as antiheparin., Coagulation of blood in vessels is, prevented by heparin, a quick acting, anticoagulant. It inhibits conversion of, prothrombin to thrombin and is used in, open-heart surgery., , EBD_7100, , IIT JEE NEET eBooks: www.crackjee.xyz

It helps filter, blood in the glomerulus of the kidney., (a) The ornithine cycle occurs in the, mitochondria of liver cells. It is meant for, urea formation., (d) Tubular r eabsorption is the second, process in urine formation through filtrate., In this, most of the filtrate passes out of, rephron tubule and returns to the blood, through peritubular capillaries. Tubular, reabsorption occurs by diffusion and, active transport., (c) Liver is the primary site of detoxification, and elimination of body wastes and, poisons. Liver detoxifies endotoxins, e.g., toxic NH3 combined with CO2 to form less, toxic urea. It also detoxifies alcohol and, convert them to acetaldehyde and then, harmless acetyl CoA., (c) Renal veins connects the kidney to inferior, vena cava. They carry the blood purified by, the kidney and carry minimum quantity of urea., (c) Renal collecting tubules are also known as, duct of bellini. These are the long narrow, tubes in the kidney that conduct urine from, the nephrons to larger ducts that leads to, urinary bladder., (d), (d) Henle's loop is responsible for the, reabsorption of water and sodium chloride, from the urine. Hence, in the absence of, Henle's loop the urine will become more, dilute., (b), 10.

It occurs in the liver., , Topicwise AIIMS Solved Papers – BIOLOGY, , 12. (d) Hypotonic urine means concentration of, urine is less than that of blood. Hypertonic, urine is more concentrated than blood and, has high osmotic pressure than the blood,, therefore it helps in reducing the loss of, water with urine. The urine is filtered by, the Bowman's capsule. The tubules of, nephrons reabsorb a large quantity of water, making urine more concentrated., 13. (a) Aldosterone is one of the important, mineralocorticoids in humans secreted by, adrenal cortex. Its main function is to, regulate sodium content of the body . It, increases sodium ion concentration in the, blood by absorbing sodium ions from renal, tubules. Excessive production of, aldosterone causes a disease aldosteronism., Its symptoms include high blood pressure,, high blood volume., 14. (c) Ultrafiltration takes place in renal corpuscle, of uriniferous tubule. It takes place in, presence of effective filtration pressure., During the process, blood is filtered and, contains only blood plasma – proteins. The, filtered blood entering into Bowman’s, capsule is called glomerular filtrate., Glomerular filtrate = Blood – (Blood, corpuscles + plasma proteins), 15. (c) In vertebrates, the lungs, liver & skin are, referred as accessory excretory organs, because besides the urinary system these, organs also participate in the removal of, waste products from the body. The liver is, the principal organ for the excretion of, cholesterol, bile pigments (bilirubin and, biliverdin) and inactivated products of, steroid hormones, some vitamins and many, drugs. It secretes these substances in the, bile and indirectly helps by formation of, urea through amino acids in ornithine cycle., It has no role in secretion of urine., 16. (d) Urea is the chief nitrogenous constituent, of human urine, though it possesses small, amount of ammonia. But when the urine is, allowed to stand for sometime, bacterial, , EBD_7100, , IIT JEE NEET eBooks: www.crackjee.xyz

And, thus it smells strongly., (a) The blood urea level rises abnormally, (uremia) in patients suffering from renal, failures. In uremia patients an artificial, kidney is used for removing accumulated, waste products like urea from the blood by, a process called hemodialysis. In this way,, , B-103, , hemodialysis saves and prolongs the life, of many uremic patients., 18. (a) Descending limb of Henle is permeable to, water but not to sodium. Consequently, water moves out into interstitium and, concentration of sodium in tubular filtrate, rises making filtrate hypertonic. Ascending, loop is impermeable to water but permeable, to sodium and makes the filtrate hypotonic.

It increases blood, pressure, respiration rate, sugar level in, blood etc. It prepares the body to face stress, at the time of interview by increasing heart, beat. So it is also called stress hormone., Renin, is, proteolytic, enzyme, synthesized,stored, and secreted by the, juxtaglomerular cells of the kidney. It plays, a role in regulation of blood pressure by, catalyzing, the, conversion, of, angiotensinogen to angiotensin I and II, which in turn stimulates the release, aldosterone from adrenal gland. Rennin, a, coagulating enzyme produced from the, stomach of human body, catalyzes the, coagulation of milk by converting milk, protein, caesin into paracaesinate. ADH, (antidiuretic hormone) is secreted by the, posterior portion of the pituitary gland that, constricts blood vessels raises blood, pressure, and reduces excretion of urine., (d) Conn's syndrome/aldosteronism is due to, hypersecretion of aldosterone. Aldosetrone, is secreted from zona glomerulosa layer of, adrenal cortex. The principle action of the, aldosterone is retention of sodium.

It inhibits the release of renin from, juxta-glomerular apparatus and thereby,, inhibits NaCl reabsorption by the collecting, duct and reduces aldosterone release from, the adrenal cortex. Inhibin is an endocrine, hormone, produced from ovary and testes., When inhibin is secreted, it inhibits the, production of follicle stimulating hormone, (FSH). It also limits the release of, gonadotropin releasing hormone. (For, other hormones refer answer no. 4), Oxytocin is the hormone secreted by, posterior pituitary that causes contraction, of the smooth muscles of myometrium, during child birth and ejection of milk from, the mammary glands. Glucagon is secreted, by the -cells of islets of langerhans of, pancreas. Its main fuction is to increase, blood glucose level. Adrenaline, (epinephrine) is secreted by adrenal, medulla.

(b) Diabetes insipidus (DI) occurs when the, kidneys are unable to conserve water as, they perform their function of filtering, blood. The amount of water conserved is, controlled by antidiuretic hormone (ADH), also called vasopressin which is secreted, by posterior lobe of pituitary gland., Diabetes inscipidus is characterised by, excessive urination and thirst. This, problem appears due to the increase in, permeability of collecting tubules., 27. (a) Adrenaline is an emergency hormone, whose concentration increases under, stress conditions. e.g. cold, stress., Adrenaline is secreted from adrenal, medulla.

B-120, , 28., , (a) Based on the mode of secretion, the glands, are of three types : mesocrine, apocrine and, holocrine. Mammary glands that are present, in mammals to feed the young ones with, milk are the example of apocrine glands. In, apocrine glands, the secretion accumulates, as secretory granules in the distal part of, the cell. This part later breaks down and, leaves as a secretion., , 29., , (a) Calcitonin or thyrocalcitonin is secreted by, parafollicular cells of thyroid stroma. It, retards bone dissolution and stimulates, excretion of calcium in urine. Thus, it lowers, calcium level in extra cellular fluid (ECF)., Parathormone is secreted by chief cells of, parathyroid gland and is also known as, Collip's hormone. It maintains blood calcium, level by increasing its absorption from food, in intestine and its reabsorption from, nephrons in the kidney. Maintenance of, proper calcium level is in fact, a combined, function of parathormone and calcitonin., When calcium level falls below normal, parathormone maintains it by promoting its, absorption, reabsorption and also by, demineralisation of bones. When blood, calcium level exceeds above normal then, , Topicwise AIIMS Solved Papers – BIOLOGY, calcitonin hormone increases excretion of, calcium in urine., 30. (c) Vasopressin or antidiuretic hormone is, secreted by posterior pituitary gland. The, deficiency of vassopressin results in a, disorder known as diabetes insipidus. The, main symptoms of diabetes insipidus are, increase in thirst and increase in urination., 31. (d) Vasopressin or anti-diuretic hormone, (ADH) reduces the volume of urine by, increasing the reabsorption of water from, the urine in the distal convoluted tubules,, collecting tubules and collecting ducts in, the kidney. It does so by rendering the walls, of these tubules leads to diabetes insipidus, (increased urination). Although the volume, of urine is increased. No glucose appears in, the urine of such patients., Diabetes mellitus is a disease which is, caused due to the failure of insulin hormone, secretion by the pancreatic islets. The, osmotic effect of glucose in the urine, considerably increases the volume of urine,, due to which thirst is also enhanced.

It usually includes amitosis or, mitotic division., , 2., , (b) Pollination by insects is entomophily,, pollination by birds is ornithophily,, pollination by bats is chiropterophily and, pollination by molluscs (snow, slugs) is, malacophily., (b) Endosperm is formed as a result of triple, fusion male gamete (n) + seconday nucleus, (2n) = Primary endosperm nucleus (3n), Secondary nucleus is formed by the fusion, of 2 polar nuclei., (a) The female gametophyte of angiosperms, is eight nucleated and seven celled. The, organized embryo sac comprises a 3 celled, egg apparatus, three antipodal cells and a, bipolar central cell. The embryo sac, although eight nucleated has only seven, cells., (d) Anemophilous flowers have feathery, stigma. It is the characteristic feature of, Gramineae family (grass). In grasses, the, stigma, that is plumose, works as an, efficient pollen catcher. Hence,, anemophilous flowers have feathery or, plumose stigma., , 3., , 4., , 5., , 6., , (b) Growth of pollen tube towards embryo is, chemotaxis due to the stimulus being, chemical in nature. The chemical stimulus, is supplied in the form of Ca++ ions., , 7., , (c) Gametes are always haploid in order to, preserve the species genetically, anatomically, and morphologically also. The embryo or, zygote is formed due to the union of male, and female gametes. (n + n = 2n). Hence, any, species which is 2n is diploid in nature., , B-127, , 8., , (a) The radicle comes out first since it grows, towards the earth.

(a) Ovum is a female gamete and is always, haploid., 11. (c) Sporopollenin, which is the hardest, substance, helps the pollen grains to, withstand extremes of temperatures. It, avoids transpiration or water loss. This, hard proteinaceous substance present in, the exine makes it also spinous in nature., 12. (a) The synergids direct the growth of pollen, tube by secreting some chemical, substances. The tip of pollen tube enters, into one synergid., 13. (d) Double fertilization involves fertilization of, the egg/oosphere (2n) and that of, secondary nucleus (3N) by two different, sperms produced in the same pollen tube., 14. (d) 1n = 21; monosomic (2n – 1) = 42 – 1 = 41;, nullisomic (2n – 2) = 42 – 2 = 40. Trisomic, (2n + 1) = 42 +1 = 43, 15. (b) In plants, normal sexual reproduction, includes meiosis and fertilization . It is, called amphimixis. But in some plants, abnormal sexual reproduction called, apomixis has been observed. Apomixis, includes abnormal sexual reproduction in, which egg or other cells like synergids and, antipodals develop into embryo without, fertilization and meiosis. The term apomixis, was given be Winkler (1908) eg. Citrus,, Rannunculus.

Once the embryo begins, to germinate, grow out from the seed, it is, called a seedling. Plants that do not produce, seeds, but do produce an embryo, include, the bryophytes and ferns. In these plants,, the embryo is a young plant that grows, attached to a parental gametophyte., , 17., , (c) Chasmogamous flowers are always open., In same bisexual plants like Commelina &, Viola. Chasmogamous and cleistogamous, flowers (which never opens throughout the, life) are found., , 18., , (d) Vegetative reproduction and apomixis both, are asexual methods of reproduction,, which gives the progeny genetically similar, to parent., , 19., , (c) In unisexual flowers, the female flower buds, are bagged before the flowers open. When, the stigma become receptive, pollination is, carried out using the desired pollen and, the flower rebagged. Hence, there is no, need of emasculation in these flowers., , 20., , (a) Geitonogamy is the transfer of pollen grains, in different flowers of same plant., , 21., , (d) Pollen grains are generally spherical and, prominent two-layered wall. The hard outer, layer (called the exine) is made up of, sporopollenin which is one of the most, resistant organic material known. It can, withstand high temperatures and strong, acids and alkali., , Topicwise AIIMS Solved Papers – BIOLOGY, , Type B : Assertion Reason Questions, 22. (a) Pollen mother cells undergo meiosis and, produce pollen grains. The pollen grains, have haploid number of chromosomes., 23. (e) Megaspore mother cell is a prominent cell, in the nucellus. It divides by meiosis and, forms a row of four haploid megaspores., 24. (d) Honey bee visit flowers to gather nectar, and turn it into honey. Visiting of insects, for nectar helps in pollination., 25. (d) Primary sporogenous cell gives rise to, microspore mother cells or pollen mother, cells (PMCs). They are sporophytic in nature, i.e., diploid. These cells undergo meiosis, (reduction division) which gives rise to 4, microspores or pollens and this formation, of microspores or pollens is called, microsporo-genesis. Microspores represent, the beginning of the gametophytic phase, and they are haploid in nature., 26. (b) The majority of angiosperms bear, chasmogamous flowers, which means the, flowers expose their mature anthers and, stigma to the pollinating agents. There is, another group of plants which set seeds, without exposing their sex organs. Such, flowers are called cleistogamous and the, phenomenon is cleistogamy., 27. (b), , Double fertilization is a characteristic, feature of angiosperms. It involves two, fusions in which one female gametes fuse, with egg cell to form zygote and other male, gamete fuses with the diploid secondary, nucleus to produce triploid primary, endosperm nucleus., 28.

(c) Head of a sperm has acrosome but the, spiral row of mitochondria are present in, the mid (connecting) piece of the sperm., 36. (c) Males have more stature than females, because of the action of male sex hormonetestosterone which is secreted by testis in, males. Body starts secreting testosterone, from the age of puberty. Its secretion is, under the influence of Luteinizing Hormone, (LH) of the anterior lobe of pituitary gland., Testosterone controls the development of, secondary sexual characters in males like, hoarseness of voice, development of facial, hairs, bone growth, calcium retention,, closing of epiphysial cartilage. The total, quantity of bone matrix increases. The, pelvic outlet is narrowed and lengthened., The strength of the pelvic bones increases, to carry more loads. That is why, males have, more stature than females after puberty, when this hormone is present in the blood., hCG (Human Chorionic Gonadotropin) is, the hormone secreted by human placenta, during pregnancy. hCG enlarges the corpus, luteum in the mother's ovary and stimulates, it to secrete progesterone., 37. (d), , 38. (c), , Testicular lobules are the compartments, present in the testes, are not involved in, the process of fertilization as whole., Fusion of male and female gametes is, called fertilization., Leydig cells, also known as interstitial cells,, are found adjacent to the seminiferous, tubules in the testicle.

The equation can, be used to calculate allele frequencies if, the numbers of homozygous recessive, individuals in the population is known., Here, p = 0.7 and q = 0.3 (given), 2pq (frequency of heterozygote), = 2 × 0.7 × 0.3 = 0.42, (a) Occurrence of natural selection and small, size of population do not meet the criteria, for a population to reach Hardy-Weinberg, Equilibrium. For Hardy-Weinberg, equilibrium to be reached, natural selection, should not be occurring. If populations are, undergoing natural selection at the locus, under consideration, allele frequencies will, be continuously changing in a specific, direction and Hardy-Weinberg Equilibrium, predicts that allele frequencies will stay, constant. It assumes that population size, is very large., (d) The skeleton of Cro-Magnon was almost, identical to the modern man., , Type B : Assertion Reason Questions, 17., , 18., , 19., , 20., , (c) We have lost all the direct evidences of, origin of life only due to destruction of, fossils on account of climatic changes and, not due to any person/(s)., (a) Ginkgo biloba, belong to the Ginkgoales, evolved during the Jurassic period and is, still existing without any morphological or, anatomical changes. Hence, both assertion, and reason are correct., (a) The banding pattern seen on stained, chromosomes from humans and, chimpanzee show striking similarities which, indicates that they have evolutionary, relationships (cytogenetic evidence)., (d) The human gestation period cannot be, shortened unless there is really a problem., , Complete development will not take place, before the gestation period of 270 – 290, days in humans., 21. (d) Coacervates are large colloidal aggregates, formed due to intermolecular attraction from, large organic molecules synthesized, abiotically on primitive earth. It mainly, consists of proteins, polysaccharides and, water. They do not fulfil the requirement, for probable precursors of life., A coacervate is a tiny spherical droplet of, assorted organic molecules which is held, together by hydrophobic forces from a, surrounding liquid. Coacervates possess, osmotic, properties, and, form, spontaneously from certain dilute organic, solutions. They were even once suggested, to have played a significant role in the, evolution of cells and, therefore, of life, itself. They are interesting not only in that, they provide a locally segregated, environment but also in that their, boundaries allow the selective absorption, of simple organic molecules from the, surrounding medium. Coacervates do not, have lipid outer membrane, hence they, cannot reproduce., 22. (c) According to Lamarck’s theory, continuous, disuse of organs makes them weak. The, theory of continuity of germplasm was, given by Weismann., If humans share ancestry with other, primates such as prosimian, monkeys etc,, then remnants of that common ancestory, should be present in our genes., 23. (b) Comparative biochemistry provides a, strong evidence for common ancestors of, living beings (e.g. proteins lymph,, enzymes, hormones, blood groups etc.), 24. (a) Darwin finches found on Galapagos, islands differ primarily in body size, feather, colour, bill shape as adaptation to type of, food available. It is a type of divergent, evolution., 25. (b) The earliest organisms that appeared on, the earth were heterotrophic because of

Page 160 :
Topicwise AIIMS Solved Papers – BIOLOGY, , B-160, , reducing atmosphere and the first, autotrophs were chemoautotrophs., An anaerobic organism does not require, oxygen for growth and may even die in its, presence. Chemotrophs are the first, organisms that appeared on earth & obtain, energy by the oxidation of electron, donating molecules in their environments., These molecules can be organic, (organotrophs) or inorganic (lithotrophs)., The chemotrophs utilize solar energy and, can be either autotrophic or heterotrophic., 26., , (c) Eohippus is the earliest fossil form in the, phylogeny of horse. Origin of horse took, place in the eocene period. The first fossil, of horse was found in North America which, was named Eohippus or "Dawn Horse. ",, that later renamed as hyracotherium., It was found during eocene period not, during pliocene., , 27., , (c) The lightest atoms of nitrogen, carbon etc., formed the primitive atmosphere. Hydrogen, atoms were most numerous and most, reactive in primitive atmosphere. Hydrogen, atoms combined with all oxygen atoms to, form water leaving no free oxygen. Thus, primitive atmosphere was reducing (without, free oxygen) unlike the present oxidizing, atmosphere (with free oxygen)., Formation of ozone layer is the, consequen ce of modern oxidizing, atmosphere having plenty of free oxygen., As more oxygen accumulated in the, atmosphere (due to photosynthesis) ozone, began to appear in the top layers., , 28. (b) The fossil of Java Ape-man was discovered, from pleistocene rocks in central Java. The, fossil of Peking man was discovered from, the lime stone caves of Choukoution near, Peking while that of Heidelberg man was, discovered in mid pleistocene. All these three, fossils come under the category of Homo, erectus. Homo erectus appeared about 1.7, million years ago in the middle pleistocene., H. erectus evolved from Homo habilis. He, was about 1.5-1.8 metres tall. He had erect, posture. His skull was flat than that of the, modern man. He had protruding jaws,, projecting brow ridges, small canines and, large molar teeth. He made more elaborate, tools of stones and bones, hunted big, animals and perhaps knew the use of fire., 29. (a) The Darwin's theory of Natural Selection, can be generalised as the change in species, by the survival of an organism exhibiting a, natural variation that gives it an adaptive, advantage in an environment. Thus,, leading to a new environmental equilibrium., The idea of the survival of the fittest, explains the above evolution by natural, selection. According to survival of the, fittest, some of the variations exhibited by, living things make it easier for them to, survive and reproduce. Thus, more, adaptive forms increase. Those which are, not fit (or less adaptive) are eliminated., 30. (b) Organic compounds that first evolved in, earth which required for origin of life were, protein and nucleic acid. All life forms were, in aquatic environment only., , EBD_7100, , IIT JEE NEET eBooks: www.crackjee.xyz

Every antigen has many, antigenic determinants called epitopes., The recognition ability of antibody is, innate and develops without exposure to, the antigen., (b) Diarrhoeal disease conditions include, frequent and excessive discharge of watery, material from the bowel. Such diseases mostly, result from ingestion of harmful germs with, food and water. E. coli, Shigella sp. &, salmonella sp. causes diarrhoea. Diarrhoea, caused by virus, bacteria or parasites, possesses two characteristics- firstly, the, offending organisms colonise the intestine, and as a consequence cause inflammation, of the intestine or enteritis; and secondly,, they upset the balance of intestinal fluid, absorption and secretion mechanism, often, enhancing the latter very considerably,, which is then manifested as watery stool, discharged frequently in large volumes., Shigella sp, Salmonella sp. are quite, closely related genera that are responsible, for diarrhoeal diseases. Dehydration is, common to all types of diarrhoeal diseases, & adequate supply of fluids & electrolytes, that provides ions, should be ensured., , B-167, , 46. (d) Blood alcohol test measures the amount of, alcohol (ethanol) in the body. Alcohol is, quickly absorbed into the blood and can, be measured within minutes of having an, alcoholic drink. The amount of alcohol in, the blood reaches its highest level about, an hour after drinking. But food in the, stomach may increase the amount of time, it takes for the blood alcohol to reach its, highest level. About 90% of alcohol is, broken down in the liver. The rest of it is, passed out of the body in urine and your, exhaled breath. Symptoms of alcohol, intoxication include confusion, lack of, coordination, unsteadiness that makes it, hard to stand or walk, or erratic or unsafe, driving. Dope test is not related to alcohol., Dope test is a blood test to know whether, a person used any drug to improve their, performance., 47. (d) Interferons are natural proteins produced, by the cells of the immune system in, response to challenges by foreign agents, such as viruses, parasites and tumor cells., Interferons belong to the large class of, glycoproteins known as cytokines., Interferons are produced by a wide variety, of cells in response to the presence of, double-stranded RNA, a key indicator of, viral infection. Interferons assist the immune, response by inhibiting viral replication, within host cells, activating natural killer cells, and macrophages, increasing antigen, presentation to lymphocytes, and inducing, the resistance of host cells to viral infection., When the antigen is presented to matching, T and B cells, those cells multiply and, strategically and specifically wipe out the, foreign substance. That is why antigen, presentation is so important to the immune, response., 48. (a) A mast cell contains many granules rich in, histamine serotonin and heparin.

But in some persons, the virus, may remain silent for long periods (upto 10, years) before symptoms of full blown AIDS, are observable. The symptoms of HIV, infection include fever, lethargy, pharyngitis,, nausea, headache, rashes etc. Persons, suffering from AIDS have a weakened, immune system due to depletion of T- helper, cells. Such persons show opportunistic, infections, i.e., infection by those fungi,, bacteria and viruses to which a person with, normal immune system is expected to be, resistant. Therefore, persons prone to, opportunistic infections may be suspected, to be infected by HIV, particularly, if the, count of T helper cells in 200/ ml or lower., Histamine is a derivative of the amino acid, histidine produced by damaged cells of, , vertebrates. When released, it has the effect, of dilating capillaries and lowering blood, pressure. Histamine is involved in allergic, and inflammatory reactions also., 53. (d) From hyperimmunized animals, the blood, serum may be taken and antibodies may be, isolated from this serum. However, the, antibodies, whenever separated from serum, after induction due to an antigen, are, usually heterogenous, because the cells, keep on producing a variety of antibodies., Monoclonal antibodies (Mabs), on the, other hand are homogeneous immunological, reagents of defined specificity so that these, can be utilized for diagnosis and screening, of disease., 54. (c) Interferons are proteins that are effective, against most viruses. They are naturally, produced by virus infected cells. The, proteins interact with adjacent cells and, make them resistant to virus attack. Now, interferons are also being manufactured, through genetic engineering., Interferons control the multiplication of, virus particles by inhibiting their protein, synthesis., 55. (b) Cancer cells divide and redivide mitotically, and is due to the activation of prooncogenes., 56. (c) Cocaine is obtained from the cocaplant,, erthyroxylum coca. Cocaine is commonly, called as coke or crack which is usually, snored. It has a potent stimulating action, of euphoria and increased energy. It, interferes with the transport of the, neurotransmitter dopamine. Its increased, dosages cause hallucinations., 57. (b) Artificially acquired passive immunity, results when antibodies or lymphocytes, that have been produced outside the host, are introduced into a host.

An ecological pyramid, of biomass shows the relationship between, biomass and trophic level by quantifying, the amount of biomass present at each, trophic level of an ecological community, at a particular moment in time., Leghaemoglobin is an oxygen scavanger., It combines with oxygen and protects, nitrogenase which catalyses the fixation of, nitrogen under anerobic conditions., If a ecosystem is to be self-sustaining,, materials such as oxygen, carbon dioxide,, water and nitrogen must to recycle, between the organisms., If population B increased while population, A decreased, these organisms were, probably in competition for the same food, (grass) and population B was better adapted., Hence, population A is competitively being, excluded from the population., Because the scorpion stalks, kills and eats, its food, it is a predator. Because it eats a, spider it is a carnivore. Because it ingests, food it is a consumer. A producer is an, autotroph as it is an organism that makes, its own food from inorganic substances. A, decomposer breaks down dead matter and, a herbivore eats only plants., Trichodesmium erythreum is a, cyanobacteria (blue green alga). Although, a blue green alga, it possesses a pigment,, phycoerythrin, which is red in colour and, imparts red colour to the water of the sea in, which it is found, hence named Red Sea., The xerophytic plants conserve water by, storing it in parenchymatous cells, specialized for this purpose.

As a result the desert insects make, themselves active and pollinate the flowers, at night. To attract the insects, most of the, desert plants bloom during night., 18. (b) Whale is carnivorous and feeds on primary, consumer and occupies the third trophic, level of the ecosystem., 19. (d) Four important functional aspects of the, ecosystem are, (i) Productivity, (ii) Decomposition,, (iii) Energy flow and, (iv) Nutrient cycling., 20. (d) The main source of energy for an, ecosystem is the radiant energy or light, energy derived from the sun. 50% of the, total solar radiation that falls on earth is, Photosynthetically Active Radiation, (PAR)., The light energy is converted into, chemical energy in the form of sugar by, photosynthesis., 6H2O + 6CO2 + Light 6C6H12O6 + 6O2, Plants utilize 2-10% of PAR in, photosynthesis., 21. (d) Net primary productivity (NPP) is the, biomass or storage of energy by green, plants. It is equal to the gross primary, productivity minus loss due to respiration., The productivity generally increases from, polar regions toward the tropics, because, of the increasing sunlight and temperature., , Type B : Assertion Reason Questions, 22., , 23., , (e) Insectivorous plants are those plants which, capture and digest live prey (normally, insects) to obtain nitrogen compounds that, are lacking in its usual marshy habitat., These plants are partly autotrophic and, partly heterotrophic., (c) In the food web, different food chains are, interconnected. Each chain is, interconnected and consists of different, trophic levels i.e. producers, consumers and, detrivorous. So, kite can also be a part of, food web., , B-195, , 24. (d) Energy flow in the ecosystem is a, unidirectional manner. There is a decline in, the amount of energy passing from one, trophic level to the next. Thus the pyramid, of energy is always upright. According to, Lindemann, only 10% of energy goes to, next trophic level., 25. (c) The organisms of all the species that live, in a particular area and interact in various, ways with one another form biotic, community. Biotic community is a grouping, that is higher than population in ecological, hierarchy. It is an assemblage of all the, populations of different organisms, occurring in an area. The different, populations of a community do not remain, isolated. They show interactions and interdependence., 26. (b) Net primary productivity is the rate of, organic matter built up or stored by, producers in their bodies per unit time and, area. Net productivity is equal to gross, primary productivity minus loss due to, respiration and other reasons. Rate of, increase in energy containing organic, matter or biomass by heterotrophs or, consumers per unit time and area is known, as secondary productivity., 27. (b) Net primary productivity is the rate of, organic matter build up or stored by, producers in their bodies per unit time and, area. Net productivity is equal to gross, primary productivity minus loss due to, respiration and other reasons. Rate of, increase in energy containing organic, matter or biomass by heterotrophs or, consumers per unit time and area is known, as secondary productivity., 28. (d) When food is made available, automatically, the next higher level of organism in the, hierarchy should increase. This is because, when the forest cover got depleted it led to, the increase in the number of endangered, species. If the deer population is more, it, automatically leads to an increase in the, tiger population.

Since then it has been used to control, mosquito borne malaria and was used, extensively as a general agricultural, insecticide., (b) Catalytic converters are involved in, reducing gaseous pollutions by converting, CO, CO2, NO2, N2 etc. Thus,, decrease the amount of pollutant. They can, not reduce emission of SPM., (b) Global warming is due to the increase in, concentration of green house gases, resulted in increase in global temperature., These global gases prevent the escape of, long wave radiations into space., (b) Deforestation results in increase in green, house gases which retains more and more, UV radiations and leads to global warming., Global warming is the warming/heating up, of the earth's atmosphere due to depletion, of ozone in the stratosphere., (c) Ozone in stratosphere is responsible for, the protection of earth from high energy, UV rays i.e. it acts as life saving screen., Ozone layer found in troposphere protects, from warming effect of earth., Due to human activities, the ozone layer in, the stratosphere starts thinning, which is, also called ozone hole. Ozone hole is, resulting in rain failure, increase in, radiation, cancer (skin) and reduction in, crop production., (a) Wetland and rice fields are the major, sources of methane. It is a green house, gas whose concentration is double now, than it was 250 years ago., (d) Pollution may be defined as an undesirable, change in physical, chemical or biological, characteristics of air, water and land, causing harmful effects on living, organisms.

(b) Stratosphere zone of Earth's atmosphere, contains a layer of ozone which protects, us from harmful ultraviolet radiations of the, sun.A group of chlorine containing, compounds called chlorofluoro carbon, (CFCs) used as coolants in air conditioners, and refrigerators are primary chemicals, responsible for ozone depletion. After their, release into troposphere, CFCs go to, stratosphere where they are broken down, by UV radiations releasing chlorine.In, presence of sunlight, chlorine breaks O3, into O2. Due to ozone depletion, its levels, decreases by 67% every year causing, higher levels of UV radiations reaching, earth which may cause eye cataracts, skin, cancer etc., 39. (a) Biotic or ecological succession is the, formation of a series of biotic communities, at the same site over a period of time one, after the other, till a stable climax community, develops over the area. It occurs generally, in bare areas. Primary succession takes place, on a biological sterile soilless primary barren, area. Secondary succession takes place in a, recently denuded area which still contains a, lot of organic debris, remains and propagules, of previous living organisms. The area has, become bared due to destruction of the, community previously present. The baring, of an area can be caused due to forest fire,, deforestation for wood, timber and habitat,, overgrazing, landslides or earthquakes,, excessive and repeated droughts, following, a cropland and repeated floods., 40. (a) Excess of nitrates in drinking water are, harmful for human health and may be fatal, for infants.

This condition is termed as, methaemoglobinemia or blue baby, syndrome. This disease can damage, respiratory and vascular systems and even, cause suffocation., 41., , 42., , (a) Water pollutants are commonly measured, by their main common denominator, called, BOD (Biochemical Oxygen Demand), i.e.,, the amount of free oxygen absorbed by, extraneous substances from water. If water, is polluted, it will consume more oxygen,, thereby enhancing the BOD of water., (b) Methane is produced by incomplete, biomass combustion, incomplete, decomposition mostly by anaerobic, methanogens., Carbon dioxide contributes about 60% of, the total global warming and share of, , methane (CH4) and chlorofluoro carbons, (CFCs) is 20% and 14% respectively. N2O, also contributes 6% in total global warming., Efficient engine such as multi point fuel, injection engine can reduce the unburnt, hydrocarbon (methane) in auto-emissions., 43. (b) Eutrophication is a natural process which, literally means well nourished or enriched., It is a natural state in many lakes and ponds, which have a rich supply of nutrients., Eutrophication becomes excessive, when, abnormally high amount of nutrient from, sewage, fertilizers, animal wastage and, detergent, enter streams and lakes causing, excessive growth or blooms of, microorganisms.

This, shows that there are the –particle which, will be passing very close to nucleus., Rutherford’s confirmed the repulsive force, on –particle due to nucleus varies with, distance according to inverse square law, and that the positive charges are, concen trated at the center and not, distributed throughout the atom. This is, the nuclear model of Rutherford., (a) When a polaroid is rotated in the path of, unpolarised light, the intensity of light, transmitted from polaroid remains, undiminished (because unpolarised light, contains waves vibrating in all possible, planes with equal probability). However,, when the polaroid is rotated in path of plane, polarised light, its intensity will vary from, maximum (when the vibrations of the plane, polarised light are parallel to the axis of the, polaroid) to minimum (when the direction, of the vibrations becomes perpendicular, to the axis of the crystal). Thus using, polaroid we can easily verify that whether, the light is polarised or not., (e) An induced current develop in a conductor, cannot moved in a direction parallel to, magnetic field. This is because when the, conductor moved in a direction parallel to, magnetic field, amount of flux linked with, the conductor does not change. Thus the, induced current develops only when, conductor cuts the lines of magnetic force., The direction of flow of induced current, can also be found by applying Fleming’s, right hand rule, when the direction of, motion of conductor inside the magnetic, field and the direction of magnetic field, action on if are known., (a) Drift velocity of free electrons is given by,, eE, vd, m, Potential difference V, Where, E =, length, eV, m, , vd, , eV, is constant., m, (c) A charged capacitor, after removing the, battery, does not discharge itself.

Hence it should handled, cautiously otherwise this may cause a, severe shock., (b) A perfect black body is one which absorbs, heat radiation of all wavelengths, which fall, on it. Such a body neither reflects nor, transmits any part of the incident heat, radiation and hence appears black, irrespective of the colour of the incident, radiation. Obviously the absorbance of a, perfect black body is unity. The radiation, given out by a perfect black body are called, black body radiations or full radiation or, total radiations., 2, , (b) As we know,, , x . This is, , phase difference between two particles, whose path difference is x. If x = , then, x = 2 . Thus, the phase difference between, two medium particles having a path, difference is 2 , i.e., the particles are in, the same phase of oscillations., (a) The presence of impurities either on the, liquid surface or dissolved in it,, considerably affect the force of surface, tension, depending upon the degree of, contamination. A highly soluble, substance like sodium chloride when, dissolved in water, increased the surface, tension of water. But the sparingly soluble, like phenol when dissolved in water, reduces the surface tension of water., (c) The orbital velocity, if a satellite close to, earth is V0, gR e , While the escape, velocity for a body thrown from the earth’s, surface is Ve, V0, Thus V, e, , 2gR e ., , gRe, 2gRe, , 1, , =, , 2, , or, Ve, 2V0, i.e., if the orbital velocity of a satellite, revolving close to the earth happens to, increase to 2 times, the satellite would, escape., , EBD_7100, , IIT JEE NEET eBooks: www.crackjee.xyz

(Removal of hydrogen, is oxidation)., Cd2+ is a 2nd group radical and Ni2+ is a, 4th group radical. So solubility product of, NiS has to be more than CdS. Further Cd 2+, gives yellow colour of CdS with H2S, but, Ni2+ gives black colour of NiS with H2S. So, both assertion and statement are wrong., (d) is correct choice., In [NiCl4]2– the Cl– ligands present in the, complex ion are less basic than CN–. As, such no pairing of electrons in the 3dsubshell takes place. This results in sp3, hybridisation and the complex so formed, is tetrahedral. On the other hand in case of, [Ni(CN)4]2– the CN– ligands present in the, complex ion are more basic than Cl–. As, such pairing of electrons can take place in, the 3d subshell. Due to pairing of electrons, in 3d subshell, one of the d-orbital becomes, vacant. This results in dsp2 hybridisation, and the complex so formed in square planar., Rusting involves reduction of absorbed, oxygen to OH– ions and oxidation of iron, to Fe2+ ions. The two ions and oxidation of, iron to Fe2+ ions. The two ions combine to, yield Fe(OH)2 which gets oxidised to give, Fe2O3.nH2O (rust).
