Homeostatic Mechanisms
Biology ⇒ Biological Systems and Homeostasis
Homeostatic Mechanisms starts at 7 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Homeostatic Mechanisms.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 9
A person drinks a large amount of water. How does the body maintain homeostasis in this situation?
A person is running on a hot day and starts to sweat. Explain how this is an example of homeostasis.
Describe how the body responds to a decrease in body temperature.
Describe the role of the kidneys in maintaining homeostasis.
Describe what happens to the body if homeostasis fails.
Explain how the body responds when blood sugar levels rise after eating a meal.
A person drinks a large amount of water. How does the body maintain homeostasis in this situation?

Which of the following best describes negative feedback in homeostasis? (1) A process that amplifies changes (2) A process that reverses changes (3) A process that stops all changes (4) A process that ignores changes
Which of the following best describes the function of receptors in homeostatic mechanisms? (1) Carry out responses (2) Detect changes in the environment (3) Store information (4) Produce hormones
Which of the following is a correct sequence in a negative feedback loop? (1) Effector → Receptor → Control center (2) Receptor → Control center → Effector (3) Control center → Effector → Receptor (4) Effector → Control center → Receptor
