Systems and Feedback Loops

Front

What is a negative feedback loop?

Back

A negative feedback loop is a process in which the output of a system reduces or counteracts the initial stimulus, helping to maintain stability within the system.

Front

In a negative feedback loop, each action creates a consequence that _____________________ the other action.

Front

What type of feedback loop moves a system to an extreme?

Back

Positive feedback loop.

Front

What is a positive feedback loop?

Back

A positive feedback loop is a process in which the output of a system amplifies or increases the initial stimulus, leading to further change in the same direction.

Front

Give an example of a positive feedback loop in nature.

Back

An example is the process of childbirth, where the release of oxytocin increases contractions, leading to more oxytocin release.

Front

What is the main difference between positive and negative feedback loops?

Back

Positive feedback loops amplify changes, while negative feedback loops counteract changes to maintain stability.

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms regulate their internal environment to maintain stable, constant conditions.

Front

What role do feedback loops play in homeostasis?

Back

Feedback loops help maintain homeostasis by regulating physiological processes in response to changes in the environment.
