False Indicate the answer choice that best completes the statement or answers the question 48. The equator is warmer than the poles because a. polar ice sheets cool the atmosphere b. the Coriolis effect pulls cold air north and south c. the sun exerts a gravitational pull on the warm air d. cooler air is less dense e. the sun's rays strike directly at the equator

Explanation / Answer

44. During El Nino the ocean currents accelerate in the Pacific Nd brings warm weather to Asia and Africa also. So the answer is option a.

45. When environmental changes occur, generalists can get to adapt so they are not that prone to extinction as that of the specialists. The statement is false.

46. Factors that limit the growth of population are collectively called environmental resistance. It includes carrying capacity, emigration,death and many more factors. The answer is option a.

47. Biodiversity or biological diversity refers to the variation in the organism with regard to genus and species. So the statement is false as it refers to fraction and not the species as a whole.
