A divide is the highest ridge of terrain separating river basins. Divides can be relatively small and cover just a few dozen miles, or they can stretch thousands of miles. On either side of a divide, water drains into separate basins. Continue Reading.
Concept 2: Mitosis and the Cell Division Cycle. Cells that are growing and dividing go through a repeating series of events called the cell division cycle (or cell cycle). During the first phase (G1), the cell grows and prepares for DNA replication, which occurs in the subsequent S phase. Further growth takes place in the G2 phase, and finally mitosis occurs in the M phase. G1, S, and G2 are collectively called interphase.
3. During what stage does the G1, S, and G2 phases happen? 4. During what phase of the cell cycle does mitosis and cytokinesis occur? 5. During what phase of the cell cycle does cell division occur? 6. During what phase of the cell cycle is DNA replicated? 7. During what phase of the cell cycle does the cell grow? 8. During what phase of the cell cycle does the cell prepare for mitosis? 9. How many stages are there in mitosis? 10. Put the following stages of mitosis in order: anaphase, prophase, metaphase, and telophase. 11. Put the following stages of the cell cycle in order: G2, S, G1, M. 12. Put the following in order: G2, G1, S, mitosis, cytokinesis. 13. Put the following actions in order: DNA replication, cell grows, cell division, cell ...
