What type of feedback loop is blood clotting?Group of answer choicesneutralnegativepresumptivepositive

Blood clotting is an example of a positive feedback loop.

Here's why:

1. In a positive feedback loop, the output of a system intensifies the response of the system. In other words, the effect of the response is amplified.

2. When a blood vessel is damaged, platelets start to adhere to the site of injury to block the bleeding. This is the initial response of the system.

3. These platelets release chemicals that attract more platelets to the site. This is the output of the system.

4. The arrival of more platelets leads to the formation of a blood clot, which further blocks the bleeding. This is an intensified response of the system.

5. Therefore, the process of blood clotting is a positive feedback loop because the response (formation of a blood clot) is amplified (more platelets are attracted to the site, leading to a larger clot).
