Bio Midterm (A/B Day)

How is cancer related to cell division?

• Mutations can cause uncontrolled cell division which causes cancerous cells to spread rapidly and take nutrients from healthy cells.

• Cancer stops cell division from happening.

• Cell division causes viruses that spread around the body and cause cancer.

• Cancer is not related to cell division.

Cells spend most of their lives in which phase?

• Interphase

• Prophase

• Telophase

• Metaphase

Cells of organisms must replicate for?

• Growth

• Replacement of dying cells

• Repair of damaged cells

• All of the above

What is the correct order of the phases of mitosis?

• Metaphase, Anaphase, Prophase, Telophase,

• Pelophase, Motophase, Anaphase, Trophase

• Prophase, Metaphase, Anaphase, Telophase

• Telophase, Anaphase, Prophase, Metaphase

What is cytokinesis?

• When 2 cells merge together to make 1 giant cell

• The end of the cell cycle when the cell divides and mitosis is complete

• The stage when DNA condenses into chromosomes

• The stage where chromosomes are pulled to opposite ends of the cell.

The G1, S, and G2 are parts of which phase of the cell cycle?

• Prophase

• Interphase

• Telophase

• Anaphase

Why do cells go through mitosis?

• to make food from sunlight

• to get air into the cells

• to create proteins

• to reproduce, grow, and repair/replace cells

Daughter cells created by meiosis II have

• half the parents DNA

• exact copy of the parent's DNA

• twice the parent's DNA
