Normal cells have a contact inhibition feedback mechanism that prevents the cells
from replicating when other cells are touched. A diagram of cells with contact
inhibition and cells without contact inhibition is shown.

Which statement best describes what will happen to cells in an organism that lack
contact inhibition?

ANSWER CHOICES

The cells will stop replicating once one layer is produced as other body cells will crowd them out.

The cells replicate into the food supply for each cell is used, causing each cell to die

The cells will continue to grow causing a tumor in the body

The cells will replicate normally replacing body cells that die
