Explanation:

1. The cell cycle is a series of events cells go through as they grow and divide.
2. G2 phase is for preparation for mitosis.
3. Mitosis results in 2 identical cells.
4. Cell division is when a cell divides into 2 daughter cells.
5. DNA is replicated in S phase.
6. When a cell divides, each daughter cell gets its own DNA copy.
7. The cell grows during interphase.
8. The first phase of mitosis is prophase.
9. The correct sequence of mitosis phases is prophase - metaphase - anaphase - telophase.
10. The two main cell - division stages are mitosis and cytokinesis.
