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:

Cell division normally happens randomly without any regulatory control mechanisms

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

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: healthy cells use regulatory systems (growth factors, cell‑cycle checkpoints, contact inhibition, apoptosis signals) to limit division. Cancer cells have lost or bypassed those controls, so they divide uncontrollably. The other choices are incorrect.
