Understanding Homeostasis and Growth

Define development.

• The process of maintaining steady conditions in the body.

• The process of growing into something.

• The process of responding to external stimuli.

• The process of maintaining internal balance.

Which of the following is an example of development?

• Sweating when it's hot.

• A tadpole growing into a frog.

• Shivering when it's cold.

• Running away from a spider.

Define homeostasis.

• The ability to grow and develop.

• The ability to respond to external stimuli.

• The ability to maintain steady conditions when outside conditions change.

• The ability to reproduce.

Which of the following is an example of homeostasis?

• A plant growing towards light.

• Sweating to cool down the body.

• A tadpole growing into a frog.

• Running away from a predator.

What is an internal stimulus?

• A change in the environment that affects an organism.

• A response to feelings within you.

• A process of maintaining internal balance.

• A process of growth and development.

Which of the following is an example of an internal stimulus?

• Running away when you see a spider.

• A plant growing towards light.

What is an external stimulus?

• A response to feelings within you.

• A change in an organism's environment that affects the organism.
