Which of the following is the best example of negative feedback?

Question

Quizplus · Accepted Answer

Negative feedback is a regulatory mechanism in which a stimulus triggers a response that reduces the stimulus. In the case of the governors on old steam engines, the increasing internal temperature of the engine triggers a response that reduces the amount of fuel being burned, thereby reducing the temperature. This is an example of negative feedback because the response (reduction in fuel) reduces the stimulus (increasing temperature). The other options do not involve a direct regulatory mechanism that reduces a stimulated response.
