The maintenance of a stable internal environment.
What is homeostasis?
The outermost shell of electrons
What is the valence shell?
The amount of heat needed to change 1 g of a substance by 1 degree
What is specific heat?
The type of interaction which occurs between the slight positive region of one polar molecule and the slight negative region of another polar molecule
What is a hydrogen bond?
The level of protein structure which consists of coils (known as alpha helices) and fold (known as beta sheets)
