Q

What is a cell what is a tissue an organ

A

Cell: structural and functional unit of living organism it is the smallest unit of life that can replicate independently

Q

What is homeostasis

A

Is the ability of a living organisms to maintain the equilibrium in its internal environment. Thank to the constant interaction of the body’s many regulatory processes certain conditions are kept stable within a narrow value range
