Homeostasis and Automatic Control Systems Quiz

What is the definition of homeostasis?

• The regulation of the internal conditions of a cell or organism to maintain optimum conditions for function in response to internal and external changes.

• The process of cells releasing energy from glucose.

• The increase in body temperature during exercise.

• The ability of the body to perform respiration.

Why do enzymes and cells require very stable conditions?

• To work well and function properly.

• To increase the body's temperature.

• To decrease the blood glucose concentration.

• To ensure they can change conditions around them.

Which of the following is NOT an example of an internal condition regulated by homeostasis?

• Blood glucose concentration

• Body temperature

• Water levels

• Skin color

What is the role of receptor cells in an automatic control system?

• To carry out the response

• To detect changes in the environment

• To process information from the Coordination Center

• To send instructions to the effector

What is a stimulus in the context of homeostasis?

• The process of respiration

• The brain or spinal cord

• A change to the environment detected by receptor cells

• A muscle or gland that carries out the response

Which of the following is a Coordination Center in the human body?

• The sweat glands

• The muscles

• The pancreas

• The skin

What is the role of an effector in an automatic control system?

• To detect changes in the environment

• To process information from receptor cells

• To carry out the response and restore the optimum level

• To regulate the internal conditions of a cell

Which of the following is NOT a feature of an automatic control system?

• Respiration

• Effector

• Coordination Center

• Receptor cells

What happens to the blood glucose concentration during exercise?

• It increases

• It falls

• It fluctuates randomly

• It remains constant

What is the primary function of the Coordination Center in an automatic control system?

• To detect changes in the environment

• To process information and coordinate the response

• To carry out the response

• To regulate the internal conditions of a cell
