Identify the initiation event.

Scenario: A person begins to exercise which causes their body temperature to increase. The temperature change is noticed and the person begins to sweat and their body temperature decreases.

• temperature change is noticed

• person begins to sweat

• body temperature decreases

• person begins to exercise

If the environment gets cold, we will often shiver in order to:

• keep body temperature the same as the external temperature
• decrease body temperature
• increase body temperature
• regulate blood pressure

Cell membranes

• control what goes in and out of the cell

• contain genetic information for the cell

• are the power house of the cell

• modify proteins

Identify the response.

Scenario: A person begins to exercise which causes their body temperature to increase. The temperature change is noticed (sensed) and the person begins to sweat and their body temperature decreases.

• the person begins to sweat

• the person begins to exercise

• change in temperature

• body temperature increases
