Animal Homeostasis starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Animal Homeostasis.
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 10
Describe how homeostasis is maintained when a person exercises vigorously.
Describe how the body responds to dehydration.
Describe the role of insulin in homeostasis.
Describe the role of the hypothalamus in homeostasis.
Describe what happens if blood glucose levels remain too high for a long period.
Explain how negative feedback helps maintain homeostasis in animals.
Explain how the skin helps maintain homeostasis.
Explain the difference between endotherms and ectotherms in terms of temperature regulation.
Explain the role of feedback mechanisms in maintaining homeostasis, using an example.
Explain why homeostasis is important for enzyme function in animals.
What is homeostasis?
A patient is unable to sweat due to a genetic disorder. Predict the effect this would have on their ability to maintain homeostasis during hot weather and explain why.
A person has a malfunctioning adrenal gland that produces too little aldosterone. Predict and explain the effect this would have on their body's ability to maintain homeostasis.
Describe how homeostatic mechanisms would respond if a person drinks a large amount of water in a short period. Include the roles of hormones and organs involved.
Explain how the process of thermoregulation in mammals demonstrates the principle of negative feedback. Include the roles of receptors, control centers, and effectors in your answer.
Explain why positive feedback is less common than negative feedback in animal homeostasis, and provide one example where positive feedback is beneficial.
