Chapter 48, Problem 14TYK
Summary Introduction
To review:
The heat transfer processes that might account for the change in body temperature in mammals.
Introduction:
An animal may lose or gain heat from its body by the processes of conduction, convection, radiation, and evaporation. These properties of heat regulation are very well depicted by the endotherms that with the help of various mechanisms acquire or lose heat.

Each was running at the same pace and increased its internal temperature to the same ratio of its initial body temperature. Which explanation correctly describes which animal would return to its initial temperature more quickly after the chase ended? A.

The tiger has a larger surface-area-to-volume ratio and will cool more quickly. D. The tiger can cool more quickly because of decreased metabolic rates within larger animals.arrow_forwardThe rate of heat loss in a mammal is regulated bya. the degree of blood flow at the surface of the skin.b. the amount of perspiration.c. behavioral adaptations.d. air currents near the animal’s body.e. all of the above.arrow_forward
