An elephant and a mouse are both running in full sunlight, and both overheat by the same amount above their normal body temperatures. When they move into the shade and rest, which animal will cool down faster?

A) They will cool at the same rate because they overheated by the same amount.
B) The elephant will because it has the lower surface area/volume ratio.
C) The elephant will because it has the higher surface area/volume ratio.
D) The mouse will because it has the lower surface area/volume ratio.

Which of the following is a true statement about body size and physiology?

A) The rate at which an animal uses nutrients and produces waste products is independent of its volume.
B) The wastes produced by an animal double as its volume doubles, and triple as its surface area triples.
C) Small and large animals face different physiological challenges because an animal's body mass increases cubically while its surface area increases as a squared function.
D) The amount of food and oxygen an animal requires and the amount of heat and waste it produces are inversely proportional to its mass.
