AP BIOLOGY

Detailed explanation-1: -Every day, our skin cells and other somatic (body) cells undergo division to replenish the dying cells. When this happens, the new cell will have the same amount of chromosomes and organelles. This process is called mitosis.

Detailed explanation-2: -Mitosis does occur in adult cardiac myocytes.

Detailed explanation-3: -The stratum basale, which is a row of columnar cells resting on the basal lamina that separates the epidermis from the dermis. Mitosis occurs exclusively at the basal cell layer and allows for the replacement of cells lost from the surface.

Detailed explanation-4: -Hepatocytes undergo rapid mitotic division during early postnatal growth, however, upon maturation and terminal differentiation, readily quiesce [30].
