How do individual cells maintain homeostasis?

The correct answer is- True.

Explanation:

Homeostasis the process of maintaining the steady physio-chemical environment in the body. Body cells maintain homeostasis by controlling the substances that enter and leave the cell with the help of the plasma membrane.

The plasma membrane is semi-permeable in nature, therefore, it allows only selective molecules to be transfer in the cell and outside the cell. Plasma membrane maintains the homeostasis by managing several factors.

It maintains a higher concentration of ions like potassium into the cell, maintains the osmotic balance of the cell by osmosis of water molecule in and out of the cell. Maintains the ionic balance of both inside and outside the cell. Therefore, the correct answer is true.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
