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 11
Describe how negative feedback helps maintain homeostasis using the example of body temperature regulation.
Describe how the body responds to an increase in blood osmolarity.
Describe the difference between endotherms and ectotherms.
Describe the role of effectors in a homeostatic control system.
Describe the role of negative feedback in homeostasis.
Explain how fever is an example of a temporary change in homeostatic set point.
