1. Which type of feedback loop works to maintain stability and bring a system back to its set point?
Positive feedback loop
Negative feedback loop
Neutral feedback loop
Open feedback loop
2. An example of a positive feedback loop in the human body is:
Regulation of body temperature
Blood sugar regulation
Blood clotting
Maintaining blood pressure
3. A feedback loop where the output of a system causes a decrease in the input is called a feedback loop.
