Model Answer
Hormones must be secreted in precise amounts for the body to function properly. This is controlled by feedback mechanisms.
Example: When blood sugar rises, the pancreas detects this and secretes more insulin, which lowers blood sugar. As the blood sugar level falls, insulin secretion is reduced. Thus, the hormone level is self-regulated.

Explanation
- The examiner expects you to state that feedback mechanism controls hormone secretion, and then support it with the insulin-blood sugar example from the textbook.
- Mention both parts of the feedback loop: rise in sugar → more insulin secreted AND fall in sugar → insulin secretion reduced. Missing either part loses marks.
- Adrenaline/thyroxin can also work as examples, but insulin is the clearest one explicitly described in the chapter.
