"Which are examples of negative feedback? Check all that apply.

A child whose thymus gland is building an immune system that gets stronger each day. When someone's adrenal gland reacts to a scary movie by secreting hormones that make the heart beat quickly. When someone's pancreas stops producing the hormone that lowers blood sugar because the person hasn't eaten recently.

Explanation:

Negative feedback is the most well-known mechanism and is directly linked to homeostasis. Most hormone secretions are regulated in this way. It is characterized by being a mechanism that reduces a certain stimulus, reversing the direction of change.

Examples of negative feedback are:

when someone's pancreas stops producing the hormone that lowers blood sugar because the person hasn't eaten recently when someone's pancreas hormone increases every time they eat, but decreases when they aren't eating when a person takes calcium supplements so a gland will stop secreting a hormone that pulls calcium from the bones
