Question

question 1 of 10 which of the following descriptions of the structure of an elephant best explains the large, flat ears filled with many tiny blood vessels known as capillaries? a. elephant ear structure allows for the slowest release of excess body heat. b. elephant ear structure allows for the lowest rate of heat gain from the environment. c. elephant ear structure allows for the greatest conservation of body heat. d. elephant ear structure allows for the most rapid heat exchange with the environment.

Explanation:

Elephants have large, flat ears with many capillaries to release excess body heat. The large surface - area to volume ratio and the presence of numerous blood vessels in the ears allow for rapid heat exchange with the environment. This helps elephants regulate their body temperature in hot climates.

Answer:

D. Elephant ear structure allows for the most rapid heat exchange with the environment.
