Answer 1

D.) The bruise slowly disappears as the arm heals.

Step-by-step explanation:

Mitosis is a phase in the cell cycle where the different sets of cromosomes are divided into two new nuclei, this means that new cells are formed, in the healing of a bruise the creation of new cells is a key process for healing, and that´s why it´s a good example of mitosis.

Answer 2

The correct answer is D.) The bruise slowly disappears as the arm heals.

As the arm heals, new healthy cells are created through mitosis while the old ones are removed.
