GCSE AQA Biology Test: Homeostasis! Trivia Quiz - Quiz


What do you know about homeostasis? Do you think you could pass a Homeostasis trivia quiz? Take 'The GCSE AQA Biology Test' to prove your knowledge. Homeostasis is an automatic process by which an individual tends to maintain stability while adjusting to the environment that keeps them alive. The homeostasis state will endure while there are constant changes in the outside world. Unsuccessful homeostasis results in the organism's death, while successful homeostasis results in survival. Take this quiz and put your knowledge of homeostasis to the test. Good Luck!

    Which of the following is an example of a receptor?

    • A.

      Muscle

    • B.

      Enzymes

    • C.

      Cutaneous receptors

    • D.

      Tendons

    Correct Answer
    C. Cutaneous receptors
    Explanation
    Cutaneous receptors are sensory receptors found in the skin that respond to various stimuli such as touch, pressure, temperature, and pain. They play a crucial role in detecting and transmitting sensory information to the brain, allowing us to perceive and respond to our environment. Unlike muscles, enzymes, and tendons, which have different functions in the body, cutaneous receptors specifically function as receptors by detecting external stimuli on the skin.

  • 3. 

    Which of the following factor can have a drastic effect on homeostasis? 

    • A.

      Physical condition of the body

    • B.

      Medications administered.

    • C.

      Diet

    • D.

      All of the above

    Correct Answer
    D. All of the above
    Explanation
    All of the factors mentioned - physical condition of the body, medications administered, and diet - can have a drastic effect on homeostasis. Homeostasis refers to the body's ability to maintain a stable internal environment despite external changes. Any alteration in the physical condition of the body, such as injury or illness, can disrupt homeostasis. Similarly, medications can affect the body's normal functioning and may lead to imbalances. Additionally, diet plays a crucial role in providing the necessary nutrients for the body's physiological processes, and an unhealthy diet can disrupt homeostasis. Therefore, all of these factors can have a significant impact on maintaining homeostasis.

  • 4. 

    What part of the brain monitors water, temperature and carbon dioxide levels in the blood?

    Correct Answer
    hypothalamus
    hypothalemus
    hypothalmus
    Explanation
    The correct answer is hypothalamus. The hypothalamus is a region in the brain that plays a crucial role in maintaining homeostasis in the body. It monitors and regulates various bodily functions, including water balance, body temperature, and levels of carbon dioxide in the blood. It receives input from sensors throughout the body and initiates appropriate responses to maintain optimal conditions.

  • 5. 

    What is the optimum temperature for the body's enzymes?

    • A.

      Zero degrees celsius

    • B.

      One hundred degrees celsius

    • C.

      Fifty four degrees celsius

    • D.

      Twenty eight degrees celsius

    • E.

      Thirty seven degrees celsius

    Correct Answer
    E. Thirty seven degrees celsius
    Explanation
    Any hotter than thirty seven degrees and the enzymes will denature, any colder and the rate of operation is reduced.

    What is the purpose of the Pancreas?

    • A.

      To secrete urine

    • B.

      To maintain body temperature

    • C.

      To kill microorganisms

    • D.

      Maintain a constant amount of glucose

    • E.

      To control body water levels

    Correct Answer
    D. Maintain a constant amount of glucose
    Explanation
    The purpose of the pancreas is to maintain a constant amount of glucose in the body. The pancreas produces and releases insulin, a hormone that helps regulate blood sugar levels. Insulin allows cells to take in glucose from the bloodstream and use it for energy or store it for later use. If blood sugar levels are too high, the pancreas releases more insulin to lower them. If blood sugar levels are too low, the pancreas releases glucagon, another hormone that raises blood sugar levels. This balance is crucial for overall health and proper functioning of the body.

    What is active transport?

    • A.

      Running

    • B.

      Pumping blood around the body

    • C.

      Absorbing chemicals against a concentration gradient

    • D.

      Moving chemicals with a concentration gradient

    Correct Answer
    C. Absorbing chemicals against a concentration gradient
    Explanation
    Active transport is the process by which cells absorb chemicals against a concentration gradient, meaning they move substances from an area of lower concentration to an area of higher concentration. This requires the use of energy in the form of ATP to transport the molecules across the cell membrane. Unlike passive transport, which relies on diffusion and does not require energy, active transport allows cells to selectively absorb essential molecules that are present in low concentrations outside the cell. This process is crucial for maintaining homeostasis and ensuring the proper functioning of cells and organisms.

  • 8. 

    _ _ _ _ _ _ _ _ is where blood is pumped through a machine to be cleaned.

    Correct Answer
    dialysis
    Explanation
    It is cleaned by the urea and other waste being allowed to pass through a selectively permeable membrane. An equal concentration of the useful substances is kept on both sides to prevent diffusion.

    What are the disadvantages of having a kidney transplant?

    • A.

      Kidney may be rejected

    • B.

      Expensive

    • C.

      Gives a new lease of life to patient

    • D.

      Cheaper than dialysis

    • E.

      Needs donors

    Correct Answer(s)
    A. Kidney may be rejected
    B. Expensive
    E. Needs donors
    Explanation
    Having a kidney transplant comes with several disadvantages. One major drawback is the risk of kidney rejection, where the recipient's immune system recognizes the transplanted kidney as foreign and attacks it. This can lead to the failure of the transplant and the need for further medical intervention. Additionally, kidney transplants can be quite expensive, involving costs for surgery, post-operative care, and immunosuppressant medications. Another disadvantage is the limited availability of suitable donors, which creates a challenge in finding a compatible kidney for transplantation.

  • 10. 

    What artery does blood enter the kidney by?

    Correct Answer(s)
    renal
    renal artery
    Explanation
    Blood enters the kidney through the renal artery. The renal artery is responsible for supplying oxygenated blood to the kidneys, allowing them to function properly. This artery branches off from the abdominal aorta and carries blood directly into the kidney, where it is then filtered and processed. The correct answer is renal artery.
