Question

which diagram shows the phase right before interphase?

Explanation:

To determine the phase right before interphase, we recall the cell cycle: interphase is followed by mitosis (M - phase), and after mitosis (specifically cytokinesis, the final stage of mitosis where the cell divides into two daughter cells), the next phase is interphase. So we need to identify the diagram showing the end of mitosis (cytokinesis) or the last stage of mitosis. The bottom - left or bottom - right diagrams show two cells (after cytokinesis). Wait, actually, the cell cycle order is: Interphase (G1, S, G2) → Mitosis (Prophase, Metaphase, Anaphase, Telophase) → Cytokinesis → Interphase. So the phase right before interphase is the end of mitosis (cytokinesis, where the cell has divided into two). Looking at the diagrams, the bottom - left diagram (two cells with nuclei, maybe after cytokinesis) or the bottom - right? Wait, let's analyze each:

• Top - left: Metaphase (chromosomes aligned at equator, spindle fibers).
• Top - right: Prophase (chromosomes condensing, nuclear envelope maybe starting to break, spindle forming).
• Bottom - left: Two cells, each with a nucleus, likely after cytokinesis (end of mitosis), so this is the phase right before interphase starts again for each daughter cell.
• Bottom - right: Maybe late telophase but not fully divided? Wait, no, the key is that after mitosis (cytokinesis), the cells enter interphase. So the diagram with two separate cells (after cytokinesis) is the phase right before interphase. So the bottom - left diagram (assuming it's the one with two cells, each with a nucleus and cell membrane separating them) is the one showing the phase right before interphase.

Answer:

The bottom - left diagram (the one with two cells, each containing a nucleus, representing the end of cytokinesis, the last stage of mitosis, which is right before interphase begins for the daughter cells).
