3.Which of the following is a major factor responsible for density-dependent (contact) inhibition
a high concentration of growth-inhibiting factors
contact with other cells provides survival signals that keep the cell alive.
signals induced in the cell by contact with neighboring cells prevent re-entry into S-phase.
cells' innate ability to "sense" when the organ of which they are a part has no need for additional cells
accumulating mutations in the cell's DNA
