Answer:
Explanation:
A) Exercise can boost your metabolism. Building lean muscle mass by exercising can slightly increase your resting metabolic rate (the amount of calories your body burns while at rest). ... That's not very much exercise for a huge increase in your energy metabolism (and ability to burn fat).

C) Maintenance of homeostasis usually involves negative feedback loops. These loops act to oppose the stimulus, or cue, that triggers them. For example, if your body temperature is too high, a negative feedback loop will act to bring it back down towards the set point, or target value, of.
D) The pancreas releases insulin automatically to move glucose from the blood to the cells. As more and more cells receive glucose, blood sugar levels return to normal. The liver and muscles store excess glucose as glycogen. Glycogen plays an important role in achieving homeostasis, a balanced state in the body.
