Answer:
climate, geology, abstraction, poverty
Explanation:
Climate: lack of precipitation can lead to a lack of water. That is why is rain is important.
Geology can also be a factor in the availability of water. When water goes under the ground, rocks let the water enter through and make a water depot that is saved underground.
Regular cleaning of the water. Even though in some places there is enough water because of the pollution, it can’t be used.
Abstraction: it is important to have a limit when using water. If the amount of water for use is smaller than the water we get through precipitation, the quantity will be balanced.
When the country is rich, it can provide regular water inspection, while in poor countries this can be a big problem.

Nitrogen fixation is the process by which atmospheric nitrogen is converted by either a natural or an industrial means to a form of nitrogen such as ammonia. In nature, most nitrogen is harvested from the atmosphere by microorganisms to form ammonia, nitrites, and nitrates that can be used by plants.
IN between the G1 and the G2 phase of the cell cycle the cell's DNA replicates its DNA. The number of chromosomes stays the same, but the amount of DNA molecules duplicates.
Therefore, our cell with 6 chromosomes in the G2 phase has 6 chromosomes and 12 DNA molecules.
