Answer:
Base
Explanation:
Deoxyribonucleic acid, DNA, is one of the four major biomolecules in living organisms. It is a polymer made up of monomers called NUCLEOTIDES. The nucleotides that make up a DNA molecule is composed of three substances namely: Sugar (deoxyribose), nitrogenous base, and a phosphate group.
However, among these three components of the nucleotide monomer, NITROGENOUS BASE is the only portion that is not the same in every DNA molecule. There are four nitrogenous bases in nature viz: Adenine, Guanine, Cytosine and Thymine. These four bases can be alternated in a DNA molecule.
Note that, phosphate group and deoxyribose sugar are constant in every DNA.

Explanation:
Wind erosion is a type of erosion caused by excessive wind. Wind erosion causes the blowing away of the top soil, which contains nutrients from one location to another. There are, however, various ways to prevent wind erosion from occuring which includes: planting of vegetation to serve as windbreak.
The growing of MORE VEGETATION COVER in form of trees can be used to control wind erosion because the trees will serve as windbreak and prevent the flooding effect of wind on the soil.
