Which of the following is an example of a stimulus in a homeostatic feedback loop?

• Sweat production

• High body temperature

• Blood vessel dilation

• Muscle shivering

What is the role of the receptor in a homeostatic feedback loop?

• To detect changes in the environment

• To process information and send signals

• To produce a response

• To amplify the stimulus

Which of the following is an example of a negative feedback mechanism?

• Blood clotting

• Childbirth contractions

• Regulation of body temperature

• Release of oxytocin during labor

What happens during a positive feedback loop?

• The body reverses a change to maintain balance

• The body amplifies a change, moving away from balance

• The body maintains a stable internal environment

• The body reduces energy consumption

Which of the following is an example of a positive feedback loop?

• Regulation of blood sugar levels

• Blood clotting

• Regulation of body temperature

• Sweat production

What is the role of the control center in a homeostatic feedback loop?

• To detect changes in the environment

• To process information and send signals

• To produce a response

• To amplify the stimulus

Which of the following is an effector in the regulation of body temperature?

• Temperature sensors in the skin

• Sweat glands

• The brain

• Blood vessels

What is the response to high body temperature in a negative feedback loop?

• Blood vessels constrict

• Muscles shiver

• Sweat glands produce sweat

• Blood vessels dilate

Which of the following is true about positive feedback loops?

• They are more common than negative feedback loops

• They help maintain homeostasis

• They amplify changes and move away from balance

• They are always harmful to the body
