Define apoptosis and explain when it happens.
it is when a cell self-destructs because the body detected a mutation within the cell during a checkpoint

500
A chromosome is made up of 2 what?
sister chromatids

Why does a large volume size hinder transportation of materials?
Materials have a smaller surface area to diffuse through making it harder to get needed supplies into the cell, and a large surface area makes it too hard for supplies to get from one part of the cell to another. (kiddie pool vs. Olympian size pool)

How does the body protect us from getting cancer?
cell cycle checkpoints or apoptosis
