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 See moreoutside 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 factor can have a drastic effect on homeostasis?
-
Physical condition of the body
-
Medications administered.
-
Diet
-
All of the above
Correct Answer
A. All of the aboveExplanation
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.Rate this question:

What is the purpose of the Pancreas?
-
To secrete urine
-
To maintain body temperature
-
To kill microorganisms
-
Maintain a constant amount of glucose
-
To control body water levels
Correct Answer
A. Maintain a constant amount of glucoseExplanation
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.Rate this question:

What two things from the list below need to be controlled by homeostasis?
-
Carbon Dioxide
-
Toenail Length
-
Water
-
Hyperactivity
-
Eye Colour
Correct Answer(s)
A. Carbon Dioxide
A. WaterExplanation
There are six things that need to be controlled by homeostasis. You can remember these by: When (water) Shall (sugar) I (ions) Clean (C02) The (temperature) Utensils (urea)Rate this question:

_ _ _ _ _ _ _ _ is where blood is pumped through a machine to be cleaned.
Correct Answer(s)
dialysisExplanation
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.Rate this question:

What part of the brain monitors water, temperature and carbon dioxide levels in the blood?
Correct Answer(s)
hypothalamus, HypothalamusExplanation
The hypothalamus is the part of the brain that monitors water, temperature, and carbon dioxide levels in the blood. It plays a crucial role in maintaining homeostasis by regulating various bodily functions, including thirst, body temperature, and respiratory rate.Rate this question:

What artery does blood enter the kidney by?
Correct Answer(s)
renal
renal arteryExplanation
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.Rate this question:

What is active transport?
-
Running
-
Pumping blood around the body
-
Absorbing chemicals against a concentration gradient
-
Moving chemicals with a concentration gradient
Correct Answer
A. Absorbing chemicals against a concentration gradientExplanation
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.Rate this question:

Which of the following is an example of a receptor?
-
Muscle
-
Enzymes
-
Cutaneous receptors
-
Tendons
Correct Answer
A. Cutaneous receptorsExplanation
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.Rate this question:

What are the disadvantages of having a kidney transplant?
-
Kidney may be rejected
-
Expensive
-
Gives a new lease of life to patient
-
Cheaper than dialysis
-
Needs donors
Correct Answer(s)
A. Kidney may be rejected
A. Expensive
A. Needs donorsExplanation
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.Rate this question:
