What term refers to certain environmental or genetic factors that could increase the chances that someone will develop cancer?

• cancer factors

• genetic factors

• risk factors

• honorary factors

Was does it mean to say risk factors are correlational and not causal?

• someone who has all the risk factors will always get cancer

• risk factors do not cause cancer, but people who have the risk factors are more likely to get the cancer

• certain lifestyles and lifestyle choices can keep your from developing most types of cancers

• genetic risk factors cause cancer, but it not in all people

What is the purpose the the cell cycle checkpoints?

• To repair damaged cells before they enter cell division.

• To remove damaged cells from an organism.

• make sure the cell doesn't skip a step in mitosis

When is apoptosis initiated?

• When DNA damage is repaired.

• When cells are removed from the cell cycle.

• When DNA damage cannot be repaired.

• only with exposure to UV
