Answer 2

Answer: Hormones are controlled by a feedback loop; information about a system is sent back to the controller of the system to improve its function.

Step-by-step explanation:

Hormones are controlled by a process known as the Negative Feedback Mechanism. This means that when hormone levels get to a particular level, a signal is sent back to the controller of the system to stop it from producing further.

For example, when blood sugar levels are high, the Pancreas will release Insulin. As the insulin works and reduces the blood sugar level this will signal the Pancreas to stop producing further.
