Explanation:

Detailed explanation-1: -(a) A negative feedback loop has four basic parts: A stimulus, sensor, control, and effector.

Detailed explanation-2: -Positive feedback mechanism definition A positive feedback system amplifies deviations and causes output state changes. Because it moves the body away from homeostasis, positive feedback mechanisms are significantly less common than negative feedback mechanisms.

Detailed explanation-3: -A negative feedback is a self-regulatory system in which it feeds back to the input a part of a system’s output so as to reverse the direction of change of the output. The process reduces the output of a system in order to stabilize or re-establish internal equilibrium.

Detailed explanation-4: -The correct answer is (a) Exercise stimulates breathing. Positive feedback occurs when the effector of a pathway increases the pathway that produced it.
