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 facilitate heat exchange with the environment. Heat is transferred from the warm blood in the capillaries to the cooler surroundings. A large surface - area to volume ratio of the ears helps in rapid heat loss.

Answer:

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