Which of the following is an example of the endocrine system maintaining homeostasis? (3 points) -Detecting a pain stimulus and sending a signal to the spinal cord to perform an automatic response
-Discharging an excessive amount of hormones in the blood and not sending a signal to stop production
-Sending a message to the pituitary gland to start producing a hormone when the levels in the body are too low
-Using sense organs to get information about the outside world and direct an appropriate body response release

-Discharging an excessive amount of hormones in the blood and not sending a signal to stop production

Explanation:

Endocrine system is regulated by negative feedback mechanisms that work to maintain homeostasis.

Concentration of hormones, and how they effect other body systems, are controlled in this manner.

For instance, the blood glucose regulation is controlled by insulin and glucagon, hormones produced by the pancreas.

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.
