Responses

It increases the number of cells, contributing directly to the size and mass of an organism.
It increases the number of cells, contributing directly to the size and mass of an organism.

It reduces the number of cells by dividing, allowing for more efficient resource use.

It alters the genetic materials in the cells, increasing diversity within tissues of the organism.
It alters the genetic materials in the cells, increasing diversity within tissues of the organism.

It produces cells with different genetic codes, so the organism can better adapt to environmental changes.

Answer 1

It increases the number of cells, contributing directly to the size and mass of an organism.

Explanation: Mitosis produces genetically identical somatic daughter cells, increasing cell number for growth and tissue repair (genetic changes and new genetic combinations are results of meiosis, not mitosis).
