Major evolutionary changes have resulted in anatomical and physiological adaptations that optimize the rate of gas exchange in animals by each of these factors except ________.
A)decreasing the distance for diffusion
B)increasing the diffusion constant for each gas
C)increasing the surface area for diffusion
D)increasing the concentration difference driving diffusion

Question

Quizplus · Accepted Answer

The diffusion constant for each gas is a physical property and cannot be altered by evolutionary changes. Evolutionary adaptations typically focus on decreasing diffusion distance, increasing surface area, and enhancing concentration gradients to optimize gas exchange.
