Ans.
Regulation of cell division includes various controlling processes that inhibit uncontrolled cell division, to prevent development of tumors. Density-dependent inhibition involves reduction in cell division, when a population of cells acquires certain density. It leads to contact between cell surface proteins of adjoining cells that gives negative signals for cell division and thus, prevent cell division.
Thus, the correct answer is 'as cells become more numerous, the cell surface proteins of one cell contact the adjoining cells and they stop dividing.'
The answer would be true.
