1. the following are pictures of cell mitosis. put the pictures in the correct order.

1. if a daughter cell has 50 chromosomes after mitosis, how many chromosomes were in the parent cell?

a. 25 b. 50 c. 100 d. 150

Explanation:

• Question 14: Mitosis has four phases: prophase, metaphase, anaphase, and telophase. Interphase is not a phase of mitosis.
• Question 15: The M phase is another name for cell division.
• Question 16: G1, S, and G2 phases are collectively called interphase.
• Question 17: A normal cell divides to form two daughter cells.
• Question 18: Mitosis has 4 phases.
• Question 19: Cancer is the uncontrolled growth of cells.
• Question 20: Cancer can be caused by the environment, viruses, and genetics.
• Question 21: Cyclin is a protein that regulates the cell cycle.
• Question 22: Centrioles help organize spindle fibers.
• Question 23: As a cell gets bigger, it needs more oxygen, not less.
• Question 24: The correct order of mitosis phases is prophase, metaphase, anaphase, telophase.
• Question 25: In mitosis, the parent cell and daughter cells have the same number of chromosomes.
