Explanation
## Step 1The first question asks when chromosomes first become visible. This occurs during the prophase stage of cell division. During prophase, the chromatin condenses into a highly ordered structure called a chromosome, which is visible under a microscope.## Step 2The second question asks when chromosomes line up in the middle of the cell. This happens during the metaphase stage of cell division. During metaphase, the chromosomes align in the equatorial plane of the cell, also known as the metaphase plate.## Step 3The third question asks which structures pull the chromosomes apart. This is done by the spindle fibers. During anaphase, the spindle fibers shorten and pull the sister chromatids apart, moving each to opposite poles of the cell.
