Answer: Homeostasis is the cell membrane is a responsible for maintaining a stable internal environment
The answer is; B
This type of inhibitors does not bind the active site of the enzyme hence does not compete with the substrate (hence its name non-competitive inhibitors). They bind the enzyme at another site and change its conformation. The substrate may still be able to bind the active site but the efficiency of catalysis can be drastically reduced threatening life. This type of inhibition cannot be cured by increasing substrate levels.
Answer: Land: Denser materials sank to the earths center and less dense materials were forced to the outer layers, forming a thin crust. Atmosphere: Less dense molecules rose to the surface. Oceans: As earth cooled, water vapor condensed to form rain which lead to the formation of oceans.
