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 7
Describe how sweating helps maintain homeostasis.
Describe how the body maintains water balance when a person drinks a lot of water.
Describe what happens to your breathing rate during exercise and explain why this is a homeostatic response.
Describe what would happen if homeostasis failed in the human body.
Explain how the body responds when blood sugar levels rise after eating.
Explain the difference between negative and positive feedback in homeostatic mechanisms.
Explain the role of the kidneys in homeostasis.
A student runs a race and starts to sweat. What is the main reason for this response? (1) To remove waste (2) To cool the body (3) To increase heart rate (4) To digest food
