Question

what happens during metaphase?the cytoplasm divides, and the two daughter cells separate.the sister chromatids separate and move to opposite sides of the cell.the chromosomes line up in the middle of the cell.a nuclear membrane forms around each set of dna.

Explanation:

Metaphase is a stage of mitosis/meiosis where the spindle fibers align the condensed chromosomes along the equatorial plane (middle) of the cell. The other options describe other cell division stages: cytoplasm division is cytokinesis, chromatid separation is anaphase, and nuclear membrane formation is telophase.

Answer:

The chromosomes line up in the middle of the cell.
