Unit 3: Homeostasis

Front

What is homeostasis?

Back

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

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of the atmosphere caused by the trapping of heat that is radiated from the Earth's surface.

Front

What is a characteristic of homeostasis?

Back

A characteristic of homeostasis is internal balance maintenance.

Front

What is a density-dependent factor?

Back

A density-dependent factor is a factor whose effects on the size or growth of a population vary with the population density, such as disease.

Front

What happens in a low prey density environment?

Back

In a low prey density environment, there is likely to be a low predator density.

Front

What is an example of an external factor affecting homeostasis?

Back

An example of an external factor affecting homeostasis is temperature changes in the environment.

Front

How do organisms respond to changes in their environment?

Back

Organisms respond to changes in their environment through various mechanisms, such as behavioral changes, physiological adjustments, and structural adaptations.

Front

What role does feedback play in homeostasis?

Back

Feedback mechanisms, such as negative feedback, help maintain homeostasis by counteracting changes that deviate from a set point.

Front

What is the significance of maintaining homeostasis?

Back

Maintaining homeostasis is crucial for the survival of organisms, as it ensures optimal functioning of biological processes.

Front

What is an example of a physiological response to maintain homeostasis?

Back

An example of a physiological response to maintain homeostasis is sweating to cool down the body temperature.
