Question

1. under a microscope, some cells can appear to be between metaphase and anaphase. explain this observation.

Explanation:

Cell division (mitosis) is a continuous process, not discrete stages. The transition from metaphase (chromosomes aligned) to anaphase (chromosomes separating) is gradual. Cells in this "between" state are undergoing the molecular and structural changes (e.g., spindle fiber shortening, chromosome movement) to move from metaphase to anaphase, so they appear as intermediate forms under the microscope.

Answer:

Cell division (mitosis) is a continuous process (not discrete stages). The transition from metaphase (chromosomes aligned at the equator) to anaphase (chromosomes separating) is gradual. Cells in this “between” state are undergoing the molecular/structural changes (e.g., spindle fiber - mediated chromosome movement) to progress from metaphase to anaphase, so they appear as intermediate forms under the microscope.
