Ultimate Trivia Quiz On Homeostasis! How Much You Know About Homeostasis Quiz

Let’s start the quiz

Homeostasis is the ability of an organism to maintain a constant steady-state with the external environment. The organism employs various mechanisms to attain a steady-state. The science of control mechanism is called cybernetics. All non-chordates, Pisces, amphibians, and reptiles are unable to maintain constancy in their internal environment so are called ectotherms or cold-blooded organisms whereas birds and mammals can maintain the internal constancy, they are called endotherms or warm-blooded organisms. So, take the Homeostasis quiz and increase your knowledge about homeostasis.
