D)Exposure to sun

Question

Quizplus · Accepted Answer

Negative feedback is the mechanism by which hormone concentrations are controlled. When hormone levels rise too high, negative feedback signals are initiated to decrease hormone production, and when hormone levels fall too low, negative feedback signals are initiated to increase hormone production. This helps to maintain a stable internal environment (homeostasis) within the body. Positive feedback, muscle contraction, and exposure to sun do not directly control hormone concentrations.
