HOMEOSTASIS QUIZ

What is homeostasis?

• The process of growing

• The process by which organisms maintain stable internal conditions

• A type of feedback loop

• The way organisms adapt to new environments

Which of the following is NOT a component involved in homeostasis?

• Sensors

• Control centers

• Effectors

• Inhibitors

What is the main purpose of sensors in homeostasis?

• To make adjustments in the body

• To carry out necessary actions

• To detect changes in the environment

• To provide energy

How does thermoregulation help maintain homeostasis?

• By maintaining stable internal temperature

• By controlling glucose levels

• By balancing electrolytes

• By increasing heart rate

Which organ plays a central role in glucose regulation by releasing insulin and glucagon?

• Liver

• Pancreas

• Kidneys

• Adrenal glands

What happens to blood vessels during vasoconstriction?

• They expand to release heat

• They contract to conserve heat

• They produce sweat

• They transport oxygen

Which hormone helps regulate water balance by controlling water reabsorption in the kidneys?

• Insulin

• Glucagon

• ADH (Antidiuretic hormone)

• Aldosterone

What role does aldosterone play in the body?

• Regulates glucose levels

• Controls body temperature

• Regulates sodium and potassium levels

• Releases energy

What kind of feedback loop is involved in stabilizing blood glucose levels?

• Positive feedback loop

• Neutral feedback loop

• Negative feedback loop

• Circular feedback loop

Why is homeostasis important for enzymes in the body?

• Enzymes do not rely on homeostasis

• Enzymes require a specific pH to function

• Enzymes need a stable environment to function efficiently

• Enzymes need external energy to work
