AQA GCSE Biology Homeostasis Quiz

What is the main function of negative feedback in homeostasis?

• To cause further deviations from the set point

• To maintain stability and balance within the body by reversing any deviations from the set point.

• To speed up the body's response to changes

• To ignore any deviations from the set point

Which hormone is responsible for lowering blood glucose levels?

• glucagon

• estrogen

• adrenaline

• insulin

What is the process by which the body regulates water balance and solute concentration?

• Transpiration

• Hibernation

• Photosynthesis

• Osmoregulation

During which phase of the menstrual cycle does ovulation occur?

• End of the cycle phase

• Mid-cycle phase

• Beginning of the cycle phase

• No specific phase

What is the primary function of the kidney in homeostasis?

• Regulate the balance of water, electrolytes, and acids in the body

• Storing excess nutrients for future use

• Producing insulin to regulate blood sugar levels

• Filtering out carbon dioxide from the blood

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

• Regulation of body temperature

• Growth and development

• Digestion of food

• Regulation of heart rate

What is the normal range for blood glucose levels in humans?

• 70-130 mg/dL

• 200-300 mg/dL

• 50-100 mg/dL

• 150-250 mg/dL

Which hormone is responsible for stimulating the reabsorption of water in the kidneys?

• Insulin

• Glucagon

• Cortisol

• ADH

What is the role of the hypothalamus in the hormonal control of the menstrual cycle?

• The hypothalamus produces gonadotropin-releasing hormone (GnRH) which stimulates the pituitary gland to release follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which then regulate the menstrual cycle.

• The hypothalamus has no role in the hormonal control of the menstrual cycle

• The hypothalamus produces estrogen and progesterone to regulate the menstrual cycle

• The hypothalamus inhibits the production of FSH and LH, disrupting the menstrual cycle

Which structure in the kidney is responsible for filtering the blood and producing urine?

• Renal pelvis

• Ureter

• Nephron

• Bladder
