Answer:
G2 phase
Explanation:
The G2 phase is the phase that comes before the actual cell division. At this point, the cell is checked for damage or deficiencies. If there are any problems in the cell that cannot be fixed, the cell cycle is stopped here. This process prevents defective cells from replicating which often results in cancer.

C

Mutations often changes ones inner and outer features which creates genetic diversity.
I hope this helps :) Have a good rest of your day!
we know where earthquakes occur the most so we know where to not settle. This also helps explain the creation of the earth.
It is likely to be a negative feedback. D is formed from B or C. D reduces the activity of the enzyme that converts A.
Estuaries can experience fairly extreme changes in abiotic conditions. For example, estuaries can at different times be dominated by the ocean when freshwater input from upstream is minimal, or it can be freshwater dominated when there is a lot of flow coming into the estuary from upstream. This means that organisms that exist within estuaries must be able to tolerate a wide range of salinities. These are called euryhaline organisms. Estuary ecosystems also receive biotic inputs from both the ocean and from the upstream river. There are therefore a lot of scavengers that thrive within estuaries, such as crabs, mud prawns and clams. One primary producer group that is important for estuaries are mangroves, but they are not found in all estuaries. Estuaries act as important nursery areas for ocean fish, who come into the estuary to spawn.
