Define buffer - CORRECT ANSWER -
form chemical systems that absorb excess acids or bases to maintain a relatively stable pH, maintains h
omeostasis
Define metabolism - CORRECT ANSWER -
refers to the whole sum of reactions that occur throughout the body within each cell and they provide
the body with energy.
Define homeostasis - CORRECT ANSWER -
Maintaining a stable internal environment, maintains state of balance
