In which situation is the principle of negative feedback most clearly shown?
Answer and explanation
Correct answer: Insulin secretion increases when blood sugar rises and decreases when the sugar returns to normal
Negative feedback is a homeostatic mechanism in which a change triggers a response that opposes or reduces the original change. When blood glucose rises, pancreatic beta cells release insulin, helping cells take up glucose and lowering the blood level. As glucose approaches normal, insulin secretion decreases. Thus option A directly shows self-correction; the other choices describe reflex or plant responses, not feedback regulation.
