The maintenance of an organism’s internal environment is called:

• compensating

• homeostasis

• balancing

• routine

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

Negative Feedback loop

• decreases the stimulus

• increases the stimulus

According to the model, what is a normal blood glucose (sugar) level?

• 270 mg/100mL

• 180 mg/100 mL

• 45 mg/100 mL

• 90 mg/100 mL

According to the model, what is the response to HIGH blood glucose (sugar)?

• Pancreas releases insulin into blood

• Pancreas releases glucagon into blood

According to the model, what is the response to LOW blood glucose (sugar)?

• Pancreas releases insulin into blood

• Pancreas releases glucagon into blood

Identify the STIMULUS.

• temperature change is noticed

• person begins to sweat

• body temperature decreases

• person begins to exercise
