Explanation:
The changes that matter undergoes can be attributed to their properties.
Physical change is one of such.

- The physical properties of matter tells us everything about what a substance is when no change is occurring to its constituents.
- In most cases physical changes are usually reversible.

Answer is prophase.
Prophase is the first phase of mitosis (a method of cell division).
