Unadulterated, refined, or pure development.
Answer:
The correct answer is -
1. Adenine - 10%
2. A-T and C-G always in DNA.
Explanation:
1. The total amount of all nitrogenous bases are equally 100% and which includes an equal amount of C and G and an equal amount of A and T in the DNA molecule.
So, Cytosine = 40%, Guanine= 40%
total = 80%
therefore, the A and thymine would be - 100 - 80 = 20
A+T = 20
A= 10, and, T = 10%
2. The complementary base pairing rule explains that DNA base pairs are Adenine always binds with thymine and cytosine bind with guanine only. Purine binds with pyrimidine always except - A-C or G- T.
<span>The non-directional hypothesis<span>
The non-directional hypothesis states that a difference exists between two variables but it does not state or predict the direction of the difference. From the question, it was stated that there are some differences between men and women but the direction of the differences between them were not identified. Therefore, Jennifer is explaining the non-directional hypothesis.

When a salt crystal dissolves in a large glass of water formed the solvent molecules surround the solute ions at the molecular level.
Explanation:
Solvation is defined as the interaction of solute particles to the solvent which stabilises the solute species in solution.
If a crystal of salt is dissolved in water, each of the ions forms of the salt will surround the water molecule. The strong covalent bonds of the water molecule will pull the ions of the crystal salt into the solution. The ions formed will now be surrounded by water molecules which is dipolar. The separated ions get thoroughly mixed in the water.
Some clouds form as air warms up near the Earth's surface and rises. ... That warmed air starts to rise because, when warm, it is lighter and less dense than the air around it. As it rises, its pressure and temperature drop causing water vapor to condense.
