Answer:
Groups 4 to 7 are most likely to be undergoing the mitotic phase of the cell cycle.
Explanation:
Since the four proteins used p16, p18, p21, and p27 are inhibitors of cyclin-dependent kinases (CDK), their absence indicates that the cell is undergoing mitosis - the cell cycle is regulated by CDKs. In the absence of these inhibitors, the cell cycle moves on forward. Because the bar for DNA replication is longer in the case for groups 4 to 7, it is indicative of the fact that these cells have gone through the mitotic phase.

Answer:
Soil erosion.
Explanation:
Soil erosion is the impact of floods on ecosystems because the floods moves very fast which takes soil with itself. Due to soil erosion, the productive layer of the soil or the layer in which nutrients are present are eroded which has a negative impact on the plants due to unavailability of nutrients. The floods moves very fast and the soil has no the ability to hold its particle tightly which leads to erosion of the soil that negatively affected the ecosystem.
