Q. Why mammals of the colder region generally have shorter ears and limbs? I. To minimize their surface volume ratio II. To minimize heat loss III. To maximize their surface volume ratio IV. To maximize heat loss Choose the correct combination from the given option
A) I and II
B) II and III
C) III and IV
D) I and IV
Explanation
Allen’s Rule According to Allen’s rule, in endothermal animals of colder areas, the extremities like feet, tail, ears, etc. tend to get smaller as compared to their relatives in warmer region due to minimise the surface volume ratio so that the heat loss could be minimize
