Can you Interpret Feedback Loops?

Front

What is a Positive Feedback Loop?

Back

A process where the output of a system amplifies the initial stimulus, leading to an increase in the effect. Example: During childbirth, the release of oxytocin increases contractions, which leads to more oxytocin release.

Front

What is a Negative Feedback Loop?

Back

A process where the output of a system counteracts the initial stimulus, leading to a decrease in the effect. Example: Regulation of blood sugar levels by insulin.

Front

What role do hormones play in feedback loops?

Back

Hormones act as signaling molecules that communicate changes in the body, triggering responses that either amplify or reduce a process.

Front

How does shivering help maintain body temperature?

Back

Shivering generates heat through muscle activity, which increases body temperature when the environment is cold.

Front

What is the significance of albedo in climate feedback loops?

Back

Albedo refers to the reflectivity of Earth's surface; higher albedo (more clouds) can lead to cooling by reflecting sunlight away.

Front

What happens during a Positive Feedback Response?

Back

Each action in a positive feedback loop amplifies the next action, leading to a rapid increase in the effect until a specific outcome is achieved.

Front

What is an example of a Negative Feedback Loop in the human body?

Back

The regulation of body temperature: when body temperature rises, mechanisms like sweating are activated to cool the body down.

Front

Define 'amplifies' in the context of feedback loops.

Back

To amplify means to increase or intensify; in positive feedback loops, each action amplifies the next action.

Front

What is the effect of increased evaporation on climate?

Back

Increased evaporation can lead to more clouds, which can affect temperature and weather patterns, potentially creating a negative feedback loop.

Front

How do feedback loops relate to homeostasis?

Back

Feedback loops are essential for maintaining homeostasis, as they help regulate internal conditions in response to external changes.
