input with options: Answer the following question given this paragraph: Hormones control many cell activities, so they are very important for homeostasis. But what controls the hormones themselves? Most hormones are regulated by feedback mechanisms. A feedback mechanism is a loop in which a product feeds back to control its own production. Most hormone feedback mechanisms involve negative feedback loops. Negative feedback keeps the concentration of a hormone within a narrow range. Q: What is the term for a loop in which a product feeds back to control its own production? A:
OPTIONS:
- Recondition Mechanism
- load mechanism
- Adaptive Mechanism
- feedback mechanism
output:
feedback mechanism
