Explanation:
The DNA could be dried -through the process of lyophilization- or stored, as a precipitate of ethanol, in liquid nitrogen (temperatures below -80 degrees Celsius). The aim is to reduce water in the stored samples as much as possible because the water can be involved in natural hydrolytic reactions (depurination, depyrimidination, deamination, and hydrolytic cleavage) that could degrade the nucleic acids of the DNA.
If the DNA is stored while being used regularly it is not advisable to store it as a precipitate of ethanol. It should be stored in aqueous form but in a slightly alkaline pH of about 8.5 to prevent acid-catalysed degradation processes.

Answer:
To keep the did chain going
Explanation:
If there's not enough species then there won't be enough diversity meaning the food chain well collapse and the animals will die out.
Explanation:
As human population increases the rate of consumption of resources also increases. Economists postulates that available resources with which to satisfy our unlimited wants as a population is highly limited.
- Increase in population leads to an increasing pressure on available resources such as freshwater, land, air, energy e.t.c.
- Increasing population easily leads to deforestation. Deforestation is the loss of forest. Forest trees are used in construction of houses and industries. Forests also takes up space and they might have to be plundered to make way for new buildings. Eventually, the forest will be lost.
- Decrease in standard of living: increasing population will lead to a low standard of living. Resources meant to accommodate a certain number of people will no longer be sufficient for them.
- High poverty rate; if population continues to rise, the rate of poverty will increase too. There will be limited resources to cater for the well being of the populace as a whole.

The answer is mitochondria
All of the listed have the same amount of nutrients unless dried or affected in some other way not said.
