Answer:
Explanation:As previously stated, DNA is a macromolecule that's made up of individual subunits called nucleotides. Each nucleotide has three parts:

A deoxyribose sugar.
A phosphate group.
A nitrogenous base.
DNA nucleotides can contain one of four nitrogenous bases. These bases are adenine (A), thymine (T), guanine (G) and cytosine (C).
These nucleotides come together to form long chains known as DNA strands. Two complementary DNA strands bond to each other in what looks like a ladder before winding into the double helix form.
The two strands are held together through hydrogen bonds that form between the nitrogenous bases. Adenine (A) forms bonds with thymine (T) while cytosine (C) forms bonds with guanine (G); A only ever pairs with T, and C only ever pairs with G.
Complementary Definition (Biology)
In biology, specifically in terms of genetics and DNA, complementary means that the polynucleotide strand paired with the second polynucleotide strand has a nitrogenous base sequence that is the reverse complement, or the pair, of the other strand.
Photosynthesis is the process by which green plants make their food by tue help of sunlight and chlorophyll using carbondioxide and water to form oxygen and glucose
cellular respiration-cellular respiration definition. The chemical process that generates most of the energy in the cell, supplying molecules needed to make the metabolic reactions of an organism run. Note: The main carrier of energy in metabolism is the molecule ATP.
Answer:
A.? i'm not 100% sure tho
Explanation:
As albedo in the Arctic region is getting higher, incoming radiant energy of the sun will be more reflected. If albedo in the Arctic region is falling, incomig radiant of the sun will be more absorbed.
Albedo is a name of overall reflectivity in terms of the Sun's spectrum.
