Question

Which are true and False (and why are they false)

_____ Homeostasis refers to “steady state” external conditions

_____ Homeostasis is an important mechanism for organisms such as humans

_____ Homeostatic mechanisms respond to changing internal conditions

_____ Homeostatic mechanisms respond to changing external conditions

_____ “Steady state” means the average of a parameter, like an internal temperature of 86°F and 111°F is 98.5°F

Answer 1

1. False
