Explanation:

1. In single - celled organisms, mitosis is used for reproduction as it results in the formation of new individuals.
2. The correct order of mitosis is Prophase, Metaphase, Anaphase, Telophase. Prophase is the start where chromatin condenses, Metaphase is when chromosomes line up in the middle, Anaphase is when sister chromatids separate, and Telophase is the final stage where the cell begins to divide into two.
3. Sister chromatids go to opposite ends of the cell during Anaphase as the spindle fibers pull them apart.
4. Chromosomes line up along the middle of the cell during Metaphase.
5. The cell begins to split into two daughter cells during Telophase when the nuclear envelopes reform and cytokinesis occurs.
6. DNA condenses into chromosomes during Prophase.
7. Mitosis results in daughter cells with the same number of chromosomes as the parent cell. So a cell with 16 chromosomes will produce daughter cells with 16 chromosomes.
8. The nuclear membrane breaks down during Prophase.
9. DNA duplicates during Interphase, which is the stage before mitosis where the cell prepares for division.
