Question

which diagram shows the phase right before telophase? (with diagrams related to mitosis and the cell cycle)

Explanation:

To determine the phase right before telophase in mitosis, we recall the mitotic phase order: prophase, metaphase, anaphase, telophase. Anaphase is the phase before telophase, where sister chromatids are pulled apart to opposite poles.

• Top - left: Likely prophase (chromosomes condensing, nuclear envelope maybe present).
• Top - right: Chromatids are separated and moving to poles (anaphase, which is before telophase).
• Bottom - left: Chromosomes aligned at equator (metaphase).
• Bottom - right: Likely telophase or interphase (nuclear envelope reforming).

So the top - right diagram shows anaphase, the phase before telophase.

Answer:

The top - right diagram (with chromosomes moving to opposite poles) shows the phase (anaphase) right before telophase.
