The process of mitosis occurs as multicellular organisms develop. which of the following best explains what happens when mitosis occurs? a. one cell divides and creates two identical cells. b. one cell differentiates into a different type of cell. c. one cell invades another cell and changes its function. d. one cell dies and is replaced by a new identical cell.

Option 'A' is correct.

Explanation:

Mitosis occurs when one cell gets divided into two daughter cells holding the same number of chromosomes as their parent cells hold, so , they are identical.

Mainly, mitosis occur in somatic cell.

Somatic cells are needed for growth, repair and development of body.

Hence, option 'A' is correct.

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products
