In the biology lab, you are shown petri dishes of cheek cell cultures. one set of cells is thin, with individual cells arranged in a single, orderly layer. the other culture shows irregular crowding of cells. the crowding cells are likely cancer cells, showing an absence of

The absence of apoptosis which is known as cell death. Additionally. there is an excessive production of cells through cell cycle.
The cell cycle is process by which a cell produces a new similar daughter cell. it composes of two main phases These are called the interphase and m-phase. The interphase has three key stages which are gap 1, s phase and gap 2. And the M-phase is where the cell itself divides with an equal number of chromosomes.

That would be a working theory.
