Answer 1

Cytoplasm, Ribosomes

Answer 2

In the process of cell division, two major cell components usually get copied before the cell starts to divide. They are:* Cytoplasm: The fluid inside a cell that surrounds the organelles. It needs to be divided evenly among the new cells.* Ribosomes: These structures play a vital role in protein synthesis, thus necessary for the new cell to function properly.Q1 (b)【Answer】: To repair the muscles【Explanation】: Mitosis is a specific process of cell division that results in two identical, diploid daughter cells. In regard to muscle cells, they need to divide by mitosis more often than many other cells in the human body primarily for repair. Whenever a muscle tissues is damaged, the division of muscle cells by mitosis allows for the repair and healing of that tissue. Moreover, muscles are subjected to constant wear-and-tear, hence the need for frequent repair. Other options are incorrect in this context as muscle cells division doesn't directly relate to muscle contraction, oxygen supply or nerve impulses transmission which can involve other cell types and mechanisms.
