Question

A biology class studies cancer cells and learns they divide uncontrollably, unlike normal cells that have regulated division patterns. What does this suggest about cell division control in healthy organisms?
Question 7 options:

Cancer cells divide slower than normal healthy cells in all tissue types

Cell division normally happens randomly without any regulatory control mechanisms

Cell division control is only important in plants, not animals or other organisms

Normal cells have mechanisms that control when and how often they divide appropriately

Answer 1

Normal cells have mechanisms that control when and how often they divide appropriately.

Explanation: cancer results from loss of those regulatory controls (e.g., checkpoints, growth factors, oncogenes/tumor suppressors), so division is not random or universally slower — it becomes uncontrolled. Control is important across organisms, not just plants.
