Animal Thermoregulation starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Animal Thermoregulation.
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 is seen moving between sun and shade throughout the day. What type of thermoregulation is this an example of?
Describe how countercurrent heat exchange works in animals like penguins.
Describe how sweating helps regulate body temperature.
Describe how vasodilation helps cool the body.
Describe one behavioral adaptation that helps animals regulate their body temperature.
Explain why reptiles are often seen basking on rocks in the morning.
A lizard is seen moving between sun and shade throughout the day. What type of thermoregulation is this an example of?
A scientist observes two mammals of different sizes in a cold environment. The smaller mammal loses heat more quickly than the larger one. Explain why this occurs, relating your answer to surface area to volume ratio.

Fill in the blank: The main organ that controls thermoregulation in mammals is the __________.
True or False: All mammals are endothermic.
True or False: Ectotherms can survive in a wider range of temperatures than endotherms.
