Consider the diagram of an internal feedback mechanism that the body uses to help maintain homeostasis. The internal feedback mechanism is shown. Stimuli goes to the receptor to the coordinator to the effector to the response and then to feedback. What is the role of the central nervous system in this model? coordinator effector response stimuli

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.

the answer is a) cell division.

hope this !
