Question

1. what can happen if checkpoints fail?

dna repairs itself more quickly
cells may divide too quickly and form a tumor
cells use energy more quickly
cells will be invaded by bacteria and destroyed

Explanation:

Cell cycle checkpoints ensure proper cell division. If they fail, cells may divide uncontrollably (too quickly), leading to tumor formation. DNA repair speed, energy use, or bacterial invasion aren't direct results of checkpoint failure.

Answer:

B. Cells may divide too quickly and form a tumor
