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 9
A lizard basks in the sun to warm up its body. Is this an example of physiological or behavioral homeostasis?
A person is running a marathon. Explain how their body maintains homeostasis during the race.
Describe how the body responds to a decrease in external temperature.
Describe how the body responds to high blood sugar levels.
Describe the role of feedback mechanisms in homeostasis.
Describe what happens to the body if homeostasis fails.

Fill in the blank: The __________ detects changes in temperature and sends signals to regulate body temperature.
Fill in the blank: The __________ system transports hormones and nutrients to help maintain homeostasis.
Fill in the blank: The __________ system works with the nervous system to regulate homeostasis through hormones.
