Homeostasis Summative

Front

What is Passive Transport?

Back

The movement of particles across a membrane from an area of high concentration to an area of low concentration without the use of energy.

Front

What direction do particles move during Passive Transport?

Back

From high concentration to low concentration.

Front

Is predation a biotic or abiotic factor?

Back

Predation is a biotic factor.

Front

What happens when an environment reaches its carrying capacity?

Back

Populations will decrease due to limited resources.

Front

What type of energy does Passive Transport use?

Back

Passive Transport uses no energy.

Front

What enters the capillaries from the alveoli during gas exchange?

Back

Oxygen (O2) enters the capillaries from the alveoli.

Front

Define Homeostasis.

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

Front

What is an example of a homeostatic process in humans?

Back

Regulation of body temperature is an example of a homeostatic process.

Front

What role do feedback mechanisms play in homeostasis?

Back

Feedback mechanisms help to maintain homeostasis by regulating physiological processes.

Front

What is the difference between positive and negative feedback in homeostasis?

Back

Negative feedback reduces the output of a system to stabilize it, while positive feedback amplifies changes to push the system further away from its starting state.
