Internal respiration involves the a) movement of air into and out of the lungs. b) diffusion of gases between the alveoli and the circulating blood. c) exchange of dissolved gases between the blood and the interstitial fluid. d) binding of oxygen by hemoglobin. e) utilization of oxygen by tissues to support metabolism.

C) exchange of dissolved gases between the blood and the interstitial fluid.

Explanation:

It's not A because that's the definition of external respiration.

It's not B because that's the definition of homeostasis.

It's not D because that binding is all part of the homeostasis.

It's not E because that's part of the metabolism of each tissue.

The right answer is C because the definition of internal respiration is the exchange of oxygen and carbon dioxide between blood and tissue through the interstitial fluid.

the answer is c.) there is a warm front in region a and a stationary front in region b.
