Circulatory systems compensate for temperature differences between the lungs and the active tissue.

A. the need to cushion animals from trauma.
B. the increased need to send chemical signals from the nervous system.
C. the slow rate at which diffusion occurs over large distances.

The correct answer is option C. "the slow rate at which diffusion occurs over large distances".

Explanation:

Circulatory systems help to maintain homeostasis by compensating from the slow rate at which diffusion occurs over large distances. Circulatory systems accelerate the rate of oxygen diffusion and allows that it reaches every part of the body, including the most distant areas from the heart, the organ that pumps blood to the whole body.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
