(a) Hint: (i) Wrong – Intercarpal is gliding joint (ii) Correct (iii) Wrong – Uric acid accumulation (iv) Wrong – White fibres have few mitochondria & abundant sarcoplasmic reticulum 38. (b) Hint: (i) Correct (ii) Correct (iii) PTH – Ca+2 metabolism, therefore, False. (iv) Vasopressin is synthesised in the hypothalamus, therefore, False. 39.

Hint: ‘FOAM’ stands for Friends of the Arcata Marsh which are responsible for an Integrated waste water treatment project. 42. (a) Hint: Only (i) is correct. (ii) False; male is smaller than female. (iii) False; takes two weeks. (iv) False; Single mating produces many progeny. 56. (b) Hint: In liverworts, rhizoids are unicellular. 58. (c) Hint: Clostridium botulinum is obligate anaerobe. Xanthomonas oryzae causes bacterial blight of rice. Citrus canker is caused by Xanthomonas citri. 43. (c) Hint: Cock and Pigeon: Male is ZZ. Therefore homogametic Man, Drosophila: Male is XY Both Grasshopper is XO heterogametic 46. (b) Hint: Trichoderma polysporum (Fungus) produces Cyclosporin A Aspergillus niger (Fungus) produces Citric acid Streptococcus (bacteria) produces Streptokinase Monascus purpureus (yeast) produces Statins 49. (b) Hint: (i) False; the Agrobacterium vector introduces the gene into the host plant (ii) False rDNA insulin doesn’t have ‘c’ peptide (iii) and (iv) are correct. 50. (d) Hint: Taken line straight from NCERT. 51. (c) Hint: Population has Age distribution and individual has Age. 52. (a) Hint: In an aquatic ecosystem GFC is the major conduit for energy flow, whereas in a terrestrial ecosystem it is through the DFC. 53. (a) Hint: Only (iii) is correct. (i) False; Animals more than plants (ii) He says it is 7 million (iii) True (iv) False – India has 50,000 genetically different strains of Rice and 1000 varieties of Mango. 54. (b) 55. (a) Hint: Harveyella is parasitic red algae. 61. (d) Hint: Smilax is a monocot have reticulate venation. China rose has spiral phyllotaxy. 63. (b) Hint: (i) and (iii) are correct. Phloem fibres provide mechanical strength; storage is a function of phloem parenchyma. Gymnosperms lack sieve tubes and companion cells. 64. (c) Hint: Gall bladder and bile duct are lined by simple columnar epithelium. 65. (d) Hint: Troponin covers the active sites and not tropomyosin. Tropomyosin occurs in the form of a long fibre. 74. (d) Hint: Glycolate is converted to Glycine in peroxisome. Glycine is converted to serine in mitochondrion. 76. (c) Hint: Dipeptidase intestine. is released from small 77. (d) Hint: AV node is located in the right atrium. Stroke volume is amount of blood pumped in one beat. 81. (b) Hint: Bicipital tuberosity is a part of radius. Styloid process is also present on radius. 83. (b) Hint: For most excitable cells, threshold is about – 50 to – 60 mV. 86. (a) Hint: Spermatids are transformed into spermato-zoa (sperms) through spermiogenesis. Spermiation is the process of release of sperms from seminiferous tubules.
