Density-dependent inhibition is explained by which process?

Explanation:

Density dependent inhibition is the process exhibited by most normal (anchorage dependent) animal cells in culture that stop dividing once a critical cell density is reached

The critical density is considerably higher for most cells than the density at which a mono-layer is formed

As cells become more numerous, the cell surface proteins of one cell contact the adjoining cells and they signal each other to stop dividing

Normal cells proliferate until they reach finite density but cancer cells are not sensitive to density dependent inhibition

we would need to see the picture to answer it

geologic time scale (for gradpoint) =)
