1. Which type of feedback loop works to maintain a stable internal environment (homeostasis)?
Positive feedback loop
Negative feedback loop
Neutral feedback loop
Both A and B
2. Childbirth is an example of which type of feedback loop?
Positive feedback loop
Negative feedback loop
Homeostatic feedback loop
None of the above
1. In a negative feedback loop, the response the original stimulus.
2. A positive feedback loop the original stimulus, leading to a greater response.
3. The maintenance of a stable internal environment in a living organism is called .
1. Blood clotting is an example of a negative feedback loop.
True
False
