Answer:
The nuclear membrane dissolves, and spindle fibers form.
Explanation:
This occurs during prophase. the chromosomes become shorter and thicker. The centrioles migrate to the opposite poles. The nuclear envelope is broken down, the nucleolus disappears, and microtubules attach to the chromosomes at the kinetochores present in the centromere. Microtubules that are associated with the alignment and separation of chromosomes are referred to as spindle fibers. Chromosomes visible under a microscope are connected at the centromere. In meiosis, the homologous chromosomes break in their DNA strands at the same point, following a recombination of the fragmented parental DNA strands into non-parental combinations, known as crossing over.
The movement of substances across the cell membrane either into or out of the cell
