In a negative feedback system, what is component that causes a change to reverse the situation and return to the value in the normal range?

The correct answer is - effector.

Explanation:

Negative feedback is one of the feedback of the homeostasis process which is a process that reverses the change occurred in the system from the set point. So, it is the mechanism that regulates the body parameter in the normal range.

Effector is one the component of other than stimulus, sensor, and control center. Effector is the component of negative feedback which causes a change to reverse the change occurred to the normal range.

Thus, the correct answer is - effector.
