Question

Which of the following statements is true concerning feedback mechanisms?

1) Positive feedback mechanisms always result in excessive damage to the host.
2) Negative feedback mechanisms tend to increase the original stimulus.
3) Negative feedback mechanisms work to prevent sudden severe changes within the body.
4) Blood glucose levels are regulated by positive feedback mechanisms.

Answer 1

Negative feedback mechanisms work to prevent sudden severe changes within the body.

Step-by-step explanation:

The true statement concerning feedback mechanisms is: Negative feedback mechanisms work to prevent sudden severe changes within the body.

Negative feedback mechanisms are prevalent in the human body as they help regulate homeostasis. They work by reducing or reversing the initial stimulus to maintain a stable internal environment. Positive feedback mechanisms, on the other hand, amplify a response, moving the system further away from the set point. Blood glucose levels, for example, are regulated by negative feedback mechanisms.
