four difference between external environment and internal environment
Answers
Internal environment
1)It is the extracellular fluid (literally, fluid outside the cells)
environment surrounding each cell.
2)The concentration of Carbon dioxide (CO2), oxygen (O2) and water (H2O) around cells/organs/ tissues inside the body of a living organism.
3(The internal environment is constant and maintenance of a constant interior environment is called homeostasis.
4)There is more stability in case of the internal environment. The reason for this is because living beings cannot endure extreme changes to aspects like water accessibility and temperature. If these aspects change too extremely, the biochemical reactions that take place within living cells that are requisite for maintaining life will be interrupted. This will cause death of the living organism
External environment
1(It is the air surrounding the living organism.
2)Bacteria, changes in light, sound, temperature, heat, and chemical and mechanical contact.
3)The external environment is too extreme for continued survival.
4)The external environment of a living organism is unstable.
