1. examine the above picture, what phase is this cell in?

a. prophase b. anaphase
c. metaphase d. telophase

1. a cell with 12 chromosomes undergoes mitosis, how many daughter cells are formed?

a 2 b. 6
c. 12 d. 24

1. if a cell that has 8 chromosomes goes through mitosis, how many chromosomes does each daughter cell have?

a 4 b. 8
c. 12 d. 16

1. which is not a phase of mitosis?

a. interphase b. prophase
c. metaphase d. anaphase

1. cells spend most of their time in this growing phase:

a. interphase b. prophase
c. anaphase d. telophase

1. t or f: cells spend 10% of their time in mitosis.

Explanation:

1. Anaphase is characterized by sister chromatids being pulled apart to opposite poles of the cell, which matches the image.
2. Mitosis always produces 2 genetically identical daughter cells regardless of the parent cell's chromosome count.
3. Mitosis results in daughter cells with the same number of chromosomes as the parent cell, as it is a process of equational division.
4. Interphase is the growth and preparation phase before mitosis; mitosis itself includes prophase, metaphase, anaphase, and telophase.
5. Cells spend the majority of their cell cycle in interphase, carrying out normal functions and preparing for division.
6. The cell cycle is ~90% interphase, so mitosis accounts for roughly 10% of the total cycle time.

Answer:

1. b. anaphase
2. a. 2
3. b. 8
4. a. Interphase
5. a. Interphase
6. True
