Homeostasis

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

What is another word that can be used to describe "homeostasis"?

• STABLE
• EQUAL
• COMPLETE
• CORRECT

Identify the STIMULUS.

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

Identify the RESPONSE.

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

• body temperature increases so the person begins to sweat

• body temperature decreases

• person begins to exercise

The "effect" of a given stimulus is the...

• response
• stimulus
• cause
• result

What type of feedback loop is shown?

• negative
• neutral 
• positive

The two types of feedback systems that help organisms maintain homeostasis are:

• positive and negative 
• receptor and effector
• static and dynamic
• minor and major

Maintaining body temperature is an example of a:

• negative feedback loop
• positive feedback loop

What is the point of a feedback loop?

• To provide the body with more energy

• To provide the body with more food

• To make sure the conditions in the body are always changing

• To make sure the conditions in the body remain stable

The kinds of chemicals that control feedback loops

• hormones

• homeostasis

• disease
