Homeostasis
keeping a constant internal environment in response to chnges/imbalances caused by the external environment.
what are the mechanisms to maintain cells, tissue within their biological tolerance limits?
Structural, functional, and behavioral
what is structural mechanism?
the animal or plant has particular physical features witch help in survival in a hostile enviorment.
what is a functional mechanism?
the metabolism of the plant or is able to adjust to changes in conditions as they were detected
what is a behavioral mechanism?
The actions and interactions of the individual, help it survive in their particular environment.
what are the levels of organization?
cell, tissue, organ, organ system, organism
cell
most basic unit of life
tissue
group of cell that perform a spefic function
organ
fromed of 2+ tissues and carries out a spefic funtion
orhan system
work together to perform a vital body function
