Negative feedback is a method of homeostatic control that see concept 40.2 (page 879) negative feedback is a method of homeostatic control that see concept 40.2 (page 879) promotes decreases in metabolic rate rather than increases ensures that conditions in an organism do not vary too much above or below their set points operates independently of most signaling mechanisms produces a response by lowering the set point of an organism's metabolism increases the speed and rapidity of negative responses to environmental stimuli

ensures that conditions in an organism do not vary too much above or below their set points

Explanation:

Homeostatis is the internal default state of an organism. When there is a change in the variables affecting the human body there are two ways by which it reacts

Positive feedback: Where the variable causing a change is further caused to change

Negative feedback: Where the variable causing a change is not allowed to  cause change in the organisms body beyond a certain point.

Hence, the option "ensures that conditions in an organism do not vary too much above or below their set points" is the correct option.
