Answer:
option D
Explanation:
Negative feedback is a mechanism in which function of a cell or an organ is decreased. It lessened the output of a system and maintain system function which is known as homeostasis. It is a regulatory mechanism of normal physiology. Some of examples are
blood sugar level regulation, regulation of blood pressure, thermoregulation and many more.
The net effect of the effector is to shut off the original stimulus or reduce its intensity, during the negative feedback mechanism to restore homeostasis.
it is a pathway that is triggered by a deviation in output and produces changes in output in the opposite direction of the initial deviation that occurs due to a stimulus.
Nerve impulse instructs the effector to bring things into balance and required range by influencing the magnitude of stimulus and maintaining homeostasis.
