Vedclass · Answer

(A) Negative feedback is a regulatory mechanism in which a stimulus causes an opposite output in order to maintain homeostasis. $A$ is an example of negative feedback because when the body temperature drops (stimulus),the body responds by constricting blood vessels and shivering (response) to increase heat production and conserve body temperature. $B$ and $C$ are examples of reflex actions or conditioned responses,not homeostatic negative feedback. $D$ is incorrect because dilation of blood vessels (not constriction) occurs during heat to release heat.
