Part a which of these phases encompasses all of the stages of mitosis but no other events?

The appropriate response is Mitosis. Amid mitosis, the chromosomes, which have just copied, consolidate and append to shaft filaments that draw one duplicate of every chromosome to inverse sides of the cell. The outcome is two hereditarily indistinguishable little girl cores. Whatever is left of the cell may then keep on dividing by cytokinesis to deliver two little girl cells.
