Question

order the following events of the mitotic (m) phase from first to last.
first

Explanation:

To solve this, we identify the stages of mitosis (prophase, metaphase, anaphase, telophase/cytokinesis) from the diagrams:

1. Prophase: The third diagram (chromosomes condense, spindle forms, nuclear envelope starts breaking).
2. Metaphase: The fourth diagram (chromosomes align at the cell equator).
3. Anaphase: The first diagram (sister chromatids separate and move to poles).
4. Telophase/Cytokinesis: The second diagram (cell pinches into two, nuclei reform).

Answer:

First: Third diagram (chromosomes condensing, spindle forming)
Second: Fourth diagram (chromosomes aligned at equator)
Third: First diagram (chromatids moving to poles)
Last: Second diagram (cell dividing into two)

(If we label the diagrams as 1,2,3,4 from top to bottom: Order is 3 (prophase) → 4 (metaphase) → 1 (anaphase) → 2 (telophase/cytokinesis))

So the sequence (first to last) of the diagram numbers (top to bottom: 1,2,3,4) is: 3, 4, 1, 2.
