(a) The stages of mitosis represented by the images are:
- A: Prometaphase/Metaphase (chromosomes condensed and visible)
- B: Metaphase (chromosomes aligned at the metaphase plate)
- C: Anaphase (sister chromatids separating)
- D: Telophase (chromosomes decondensing within new nuclei)
- E: Cytokinesis (cell elongating)
- F: Telophase/Cytokinesis (cell dividing into two daughter cells)
(b) During prophase, the following key events occur:
- Chromatin condenses into visible chromosomes.
- The nuclear envelope breaks down.
- The mitotic spindle begins to form from the centrosomes, which move towards opposite poles of the cell.
