Cancer

Which of the following correctly lists the levels of organization from smallest to largest?

• Cell- Organ- Organ System- Tissue- Organism (You)

• Tissue- Cell- Organ- Organ System- Organism (You)

• Cell- Tissue- Organ- Organ System- Organism (You)

What is a mutation?

• A change or "typo" in the cell's DNA

• A correct copy of the cell's DNA

• When a cell doesn't grow

Usually, a mutated cell-

• is harmless

• changed back to normal

• is destroyed

What is the problem with a mutated cell that continues to divide?

• There is nothing wrong with the daughter cells.

• It makes the other cells around it mutate too.

• It passes on the mutated DNA to the daughter cells which results in two cells that are abnormal.

How do the methods of radiation and chemotherapy work to treat cancer?

• It fixes the mutated DNA inside the cancer cells.

• They attack the cancer cells and fight off the infection.

• They destroy the cell's mutated DNA.

What type of cell reproduces more often?

• Cancer cell

• Liver cell

• Hair cell

Chemotherapy targets-

• only the smaller cells

• cancer cells

• rapidly dividing cells

The side effects of chemotherapy often include hair loss, nausea, fatigue, and weight loss. This is because-

• all types of cancer causes hair loss, nausea, fatigue, and weight loss

• chemotherapy targets all frequently dividing cells, not just cancer cells.

• it only destroys cancer cells.

Cancer occurs when-

• cells remain small and do not grow.

• cells grow and divide uncontrollably.

• you catch from it another person with cancer.
