All other things being equal, species that inhabit cold climates tend to be larger than related species that inhabit hot climates. For instance, the Alaskan hare is the largest North American hare, with a typical mass of $5.0 \mathrm{~kg},$ double that of a jackrabbit. A likely explanation is that A. Larger animals have more blood flow, allowing for better thermoregulation. B. Larger animals need less food to survive than smaller animals. C. Larger animals have larger blood volumes than smaller animals. D. Larger animals lose heat less quickly than smaller animals.
The rate of heat loss in a mammal is regulated by a. 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.
