Question

1. what is the key event that occurs during metaphase? a. the cells cytoplasm divides into two. b. sister chromatids are pulled apart to opposite poles. c. chromosomes align in a single file line at the cells center. d. the nuclear envelope reforms around two new sets of chromosomes. 5. the separation of sister chromatids and their movement toward opposite poles of the cell happens during which phase? a. anaphase b. prophase c. metaphase d. telophase 6. what is cytokinesis, as described in the passage? a. the process of dna replication. b. the formation of the spindle fibers. c. the division of the cells nucleus. d. the division of the cells cytoplasm. 7. what is the final outcome of one complete cycle of mitosis and cytokinesis? a. one parent cell and one identical daughter cell. b. two daughter cells that are genetically identical to the parent cell. c. four daughter cells, each with half the number of chromosomes as the parent cell. d. two daughter cells that are genetically different from the parent cell.

Explanation:

• For question 4, during metaphase of mitosis, chromosomes align at the cell's equatorial plate (center) in a single - file line.
• For question 5, anaphase is the stage where sister chromatids separate and move to opposite poles of the cell.
• For question 6, cytokinesis is the division of the cell's cytoplasm to form two separate daughter cells.
• For question 7, one complete cycle of mitosis and cytokinesis results in two daughter cells that are genetically identical to the parent cell.

Answer:

1. C. Chromosomes align in a single file line at the cell's center.
2. A. Anaphase
3. D. The division of the cell's cytoplasm.
4. B. Two daughter cells that are genetically identical to the parent cell.
