A person cuts the skin on their arm. New skin cells are made by mitosis to repair the cut.
Each skin cell contains 46 chromosomes.
State the number of chromosomes in each daughter cell produced when a skin cell divides by mitosis.
Explain why the new skin cells are genetically identical to the old skin cells.
Mitosis is also important in other processes.
Name two processes, other than repair, that depend on mitosis.
