When animal cells are grown in a petri dish, they typically stop dividing once they have formed a single, unbroken layer on the bottom of the dish. this arrest of division is an example of mitosis s phase. density-dependent inhibition. lack of nutrients?

This arrest of division is an example of Density-dependent inhibition. Density dependent inhibition is the process where crowded cells stop dividing; the number of cells in an area force competition for nutrients, space, and growth factors, therefore, when cells are crowded, they get signals to stop dividing. In density dependent inhibition, when density is high there is no cell division and when the density is low cells divide.

The answer is overmatching
