The correct answer is:
fixation
Explanation:
Nitrogen fixation is a method by which nitrogen in the Earth's atmosphere is converted into ammonia or other molecules prepared to living organisms. Nitrogen fixation is carried by a diversity of bacteria, both as free-living organisms and in symbiotic association with plants. Because it is the primary source of the nitrogen in the soil, nitrogen that plants need to grow, nitrogen fixation is one of the most critical biochemical processes on Earth
1. Proteins are made from subunits called amino acids. There are 20 different amino acids which are responsible for the variation of proteins. Those amino acids are linked together by peptide bonds and form polypeptide chains. According to the polypeptide structure, there are 4 levels in protein structure as primary structure, secondary structure, tertiary structure and quaternary structure.
2. Starch is a type of carbohydrate. Hence, the subunits of starch are sugar molecules which are called as glucose. The elements of glucose are C,H,O. By linking glucose units with 1-4 alpha glycosidic bonds, the polysaccharide chain is formed. Hence, starch is also a polysaccharide<span>.

3. DNA is made from subunits called nucleotides. Nucleotides consist of deoxyribose, phosphate group and nitrogenous base.
There are two types of nitrogenous base as purines and pyrimidines. Adenine (A) and guanine (G) are purines and
thymine (T) and cytosine (C) can be seen as pyrimidines. Those nucleotides are linked together by sugar phosphate bonds which are formed between 5' phosphate group and 3' -OH group<span>.</span><span>

Discharge is the act of removing or losing charge. If the velocity increases, the discharge would increase (i'm guessing that the width and depth of the area is increasing).
Answer:
C.) breakdown of carbohydrates
Explanation:
Carbohydrates store energy. By breaking down carbohydrates, we can access this energy to do tasks, repair our bodies, etc. All of the other answers involve processes that require energy.
Answer:
Griffith concluded that in the presence of the dead S-type pneumococcus cells, some of the living R-type cells had been transformed into virulent S cells. These cells were able to grow in the bodies of the mice, causing pneumonia and multiplying in the blood. ... The DNA alone caused bacterial transformation.
Griffith introduced heat-killed 'S'- strain bacteria Streptococcus in to a mouse along with live 'R' strain bacteria. ... Some 'transforming principle' transferred from the heat-killed 'S' strain had enabled the 'R' strain to synthesise a smooth polysaccharide coat and become virulent.
In this experiments, Griffith injected mice in the lab with live R-type of bacteria. They did not suffer from the disease. ... He thus concluded that heat-killed smooth type bacterial caused a transformation of the living rough type bacteria. This experiment suggested that DNA and not proteins are the genetic material.
