Question

what happens to a cell when it becomes cancerous?
the cell no longer responds to signals that regulate the cell cycle.
the cell dies.
the cell grows much larger and never stops growing.

Explanation:

Cancer cells have genetic mutations that disrupt normal cell - cycle regulation. They no longer respond to signals that would normally control cell division, growth, and death. Instead of dying or growing in a regulated manner, they divide uncontrollably.

Answer:

The cell no longer responds to signals that regulate the cell cycle.
