False false false. Biology is a very dynamic science because we are still discovering new species. As our technology advances, we are learning more than ever before. Case in point: when moi' was in school, there were only 3 kingdoms! The atom only contained 3 particles. Pluto was a planet. Man had never been to the moon! Look at us now!
Hello the answer is easy
A. to prove that here is proof
The major purpose of the cell membrane is to regulate the types of substances that enter the cells and leave the cell, thus, it is a semi permeable structure.
The structure of the cell membrane help the cell in regulating the amount of the water inside the cell because, when the optimum amount of water is inside the cell, the membrane will not allow the pasage of water molecules into the cell again.
And in a situation, where the concentration of substance inside the cell is above the normal concentration, the cell membrane will allow the required amount of water to flow into the cell in order to reduce the concentration.
Also, the phospholipid bilayers that are found in the cell membrane help to regulate water homeostasis of the cell by using its hydrophobic tail to repel water molecules and thus keep them out or inside of the cells.
