Read each question carefully and provide your best answer. This worksheet will assess your understanding of feedback loops in biological systems.
1. Which type of feedback loop works to maintain a stable internal environment (homeostasis)?
Positive feedback loop
Negative feedback loop
Neutral feedback loop
All of the above
2. Childbirth is an example of what type of feedback loop?
Positive feedback
Negative feedback
Homeostatic feedback
Equilibrium feedback
1. Negative feedback loops always result in a decrease in the initial stimulus.
True
False
2. The regulation of blood glucose levels is an example of a positive feedback loop.
True
False
1. In a feedback loop, the response enhances the original stimulus.
2. is the process by which organisms maintain a stable internal environment.
1. Describe the key difference between a positive and a negative feedback loop, providing one example for each.
2. Explain how the body uses a negative feedback loop to regulate body temperature when it gets too high.
Match each biological process with the type of feedback loop it primarily demonstrates.
1. Blood clotting
a. Negative Feedback
2. Regulation of blood pressure
b. Positive Feedback
3. Fruit ripening
c. Homeostasis
