A) Immediately after an embryo forms, it begins to replicate new cells. What is the most likely

type of cells that form during the first few divisions? (1 point)
multipotent cells
oligopotent cells
pluripotent cells
totipotent cells

The most likely type of cells that form during the first few divisions of an embryo are totipotent cells.

A) Why is mitosis a longer and more complicated process of cell division than binary fission?

(1 point)
Binary fission does not replicate DNA
Mitosis occurs in the cytoplasm and does not require a nucleus
Mitosis has check points that must be met to continue the cycle
Binary fission produces two identical daughter cells

The reason mitosis is a longer and more complicated process of cell division than binary fission is because mitosis involves several steps and has checkpoints that must be met to ensure proper cell division. Mitosis requires the replication and separation of DNA, the formation of a mitotic spindle apparatus, and the division of the cytoplasm. In contrast, binary fission is a simpler process that occurs in prokaryotes, where the DNA replicates and the cell divides into two identical daughter cells without the involvement of a mitotic spindle apparatus or checkpoints.
