Question

Which of the following is NOT a common characteristic of a negative feedback system? a. regulates conditions in body that remain fairly stable over long periods b. important in maintaining homeostasis c. involves control centers in the nervous or endocrine system d. stimulates changes that reverse the direction of the stimulus e. usually requires an event outside the feedback system to shut it off

Answer 1

C.) involves control centers in the nervous or endocrine system

Step-by-step explanation:

Negative feedback systems typically do involve control centers in the nervous or endocrine system. These control centers receive information about changes in a physiological parameter and initiate responses to counteract those changes and restore homeostasis.

The other options, a, b, d, and e, are common characteristics of negative feedback systems:

a. Negative feedback systems regulate conditions in the body that remain fairly stable over long periods, which is a key aspect of maintaining homeostasis.

b. Negative feedback is important in maintaining homeostasis by preventing excessive deviations from the set point.

d. Negative feedback stimulates changes that reverse the direction of the stimulus, bringing the physiological parameter back to the set point.

e. Negative feedback systems usually require an event outside the feedback system (like the presence of a specific hormone or a change in environmental conditions) to shut it off once homeostasis is restored.
