41 - 50 of 60 Questions

#	Question	Ans
41.	An association between two organisms in which both benefit is called A. parasitism B. commensalism C. symbiosis D. Predation E. competition	C
42.	Which of the following is not an outcome of ecological succession? A. There is a progressive change in species structure, organic matter and energy flow B. The climax stage consists of a comparatively long lasting species composition C. There is no dynamic equilibrium between the community and habitat in the climax stage D. Communities occurring later in the sequence of succession are more complex E. There are fewer dominant species in the late stages of succession.	A
43.	Which of the following is not an effect of over-crowding on a population? A. Death B. Competition C. Commensalism D. Aggression E. Cannibalism Show Content Detailed Solution Commensalism is a long-term biological interaction in which members of one species gain benefits while those of the other species neither benefit nor are harmed. - Hence; commensalism is not an effect of OVERCROWDING.	B
44.	The diagram above represent the shape of major group of bacteria The groups staphylococci and streptobacilli are represented by A. I and II B. II and IV C. III and VII D. IV and VII E. IV and VIII	D
45.	Prevention of erosion could best be carried out by A. crop rotation and mulching B. contouring of slopping ground and afforestation C. grazing terracing and shifting cultivation D. strip cropping and poaching E. bush fallowing and crop rotation.	B
46.	The following are useful measures for conserving forest except A. preventing and controlling accidental forest fire B. encouraging the use of charcoal for industrial and domestic purposes C. combating and preventing plant diseases D. reafforestation of depleted forest E. protection of young growing trees	B
47.	The following practices are aimed at soil conservation except A. contour ridging B. application of manures C. strip cropping D. bush clearing E. crop rotation	D
48.	Which of the following natural resources is most readily available to all organisms? A. Water B. Oil C. Food D. Air E. Mineral salts	D
49.	Which of the following is an example of discontinuous variation? A. Height B. Size of head C. Blood group D. Skin colour E. Length of foot	C
50.	Hereditary variation is best described as A. characters transmitted from generation to generation B. traits acquired from diseases C. characters that show up due to social conditions D. traits acquired from habits and environmental conditions E. characters that result from physical injuries.	A
