The following diagram shows a simulated microscopic view of a tissue sample taken from a patient where the cells have been squashed onto a slide and stained to visualize the cell's DNA. In the diagram, click or tap on the center of all cells that appear to be involved in any of the four stages of mitosis. Make sure to mark as close to the center of the cell as possible. In the diagram from Question 5, count the total number of cells visible and write the total number of cells in the space below: In the diagram from Question 5, count the number of cells that you had marked as currently undergoing any of the four phases of mitosis. How many cells in total are currently undergoing mitosis? Write this number in the space below: The mitotic index is a calculated value that represents the percentage of cells in a sample that are actively dividing. It involves counting the total number of cells present including those actively dividing or those in interphase, the total number of cells that…

The figure below shows the number of chromosomes observed in an actively dividing cell at each stage of cell division. A B number of chromsomes per cell C 100 90 D 80 A bar graph comparing the number of chromosomes at different stages of cell division. 20 Which of the following best explains the change in the number of chromosomes between metaphase and anaphase? prophase metaphase anaphase telophase cytokinesis stage of cell division New chromosomes formed during prophase are doubled during anaphase. DNA replication occurs between metaphase and anaphase, doubling the number of chromosomes. During metaphase, a cell contains identical copies of each chromosome, and then trans- forms into sister chromatids. During anaphase, the chromatids are separated, each becoming independent chromo- somes in its respective new cell
