#	Question	Ans
21.	The function of the part labelled III is to A. contract to pull the hair erect B. conduct nervous impulses C. carry blood and nitrogenous waste D. produce oil for the skin	A
22.	The type of reproduction that is common to both Hydra and yeast A. conjugation B. binary fission C. grafting D. budding	D
23.	The eggs of birds contains relatively larger quantities of yolk than those of amphibians and reptiles because A. birds are generally bigger in size B. embryonic development is longer in birds C. those of birds are fertilized internally D. birds lay shelled eggs	B
24.	Epigeal germination of a seed is characterized by A. more rapid elongation of the hypocotyl than the epicotyl B. more rapid elongation of the epicotyl than the hypocotyl C. equal growth of both the hypocotyl and epicotyl D. lack of growth of the hypocotyl	A
25.	Nervous control differs from hormonal control in that the former A. involves only chemical transmision B. is a lower process C. produces short-term changes D. has no specific pathway	C
26.	If a nursing mother is not producing enough milk, her hormonal system is probably deficient in A. prolactin B. testosterone C. thyroxin D. insulin	A
27.	The two keys cation involved in the action potential of nervous transmissions are A. Na⁺ an Fe²⁺ B. Mg²⁺ and K⁺ C. Na⁺ and K⁺ D. Fe²⁺ and Mg²⁺	C
28.	A caterpillar and an aphid living in different parts of the same plant can be said to A. occupy the same ecological niche B. be in different habitat C. occupy different ecological niche D. be in the same microhabitats Show Content Detailed Solution The caterpillar and the aphids occupy two different spaces or parts of the plant. Hence they occupy different ecological niches.	C
