Which of the following describes a positive feedback loop?
ehidna [41]

Answer;

An example of positive feedback loop is;

-When a pregnant woman begins to go into labor, the body sends hormones that increase the intensity of the labor contractions.

Explanation;

-Feedback loops are therefore the process whereby a change to the system results in an alarm which will trigger a certain result. The result will  then either increase the change to the system or reduce it to bring the system back to normal.

-Feedback loops are important because they allow living organisms to maintain homeostasis (maintenance of internal environment of the body constant).

-A positive feedback loop occurs in nature when the product of a reaction leads to an increase in that reaction.  It moves a system further away from the target of equilibrium, by amplifying the effects of a product or event and occurs when something needs to happen quickly.
