When skin cells are damaged by ultraviolet radiation from the sun, they are replaced by new ones. Explain how this fact provides evidence that supports one or more parts of cell theory?

See the answer below

Explanation:

When skin cells are damaged by ultraviolet radiation from the sun, the cells present in the tissue of the skin are triggered to start dividing by mitosis in order to produce new cells that replace the damaged cells. Thus, new cells are produced from the old cell.

This phenomenon agrees with the part of the cell theory that says that cells can only arise from preexisting cells. More specifically, cells are only able to arise from preexisting cells through the process of cell division.

meiosis is the correct answer

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
