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:
The correct answer will be option-B
Explanation:
A species is a group of similar organisms which interbreed with the individual of the same group of closely related individuals.
Species are reproductively isolated by various mechanisms, one of which is due to the behavior.
When the species are not able to reproduce to different species due to the differences in their behaviour in terms of mating rituals which could be due to different mating rituals or a different way of mating like observed in the grasshoppers is known as behavioral reproductive isolating mechanism.
In grasshoppers, the grasshopper's species cannot interbreed due to the differences in the mating songs as a part of the behavior.
Thus, Option-B is the correct answer.
Most of the fungi plants are saprophytic,so they use dead organic matter and converts it into inorganic compounds, which primary producers use in their metabolisms.
Answer: These animals eat algae in the water.
Explanation: They clean the water in other words.
