KEY:cell cycle | cell division | mitosis | reproduction | unicellular organismMSC:moduleA_Module Review29.ANS: DA is incorrect because the image shows cytokinesis. During mitosis, the nucleus divides, but the cell itself does not divide until cytokinesisB is incorrect because during anaphase, chromatids separate. This stage occurs before the division of the cell.C is incorrect because if the image showed interphase, the cell would be undergoing normal life activities and not dividing.D is correct because the phases of mitosis are complete, and the new cells are undergoing the final division into two daughter cells. This stage of the cell cycle is cytokinesis.

The two stages that happen before are interphase and mitosis. B is correct because the image shows cytokinesis. The two stages that happen before cytokinesis are interphase and mitosis.C is incorrect because the image shows cytokinesis. Interphase and mitosis happen before cytokinesis.D is incorrect because the image shows cytokinesis.

The new, healthy cells replace injured or damaged cells.C is correct because damaged cells are replaced with new cells when healthy cells divide; this process helps keep organisms healthy.
