Answer: The correct answer is D. Adenine
Explanation:
There are two types of nucleic acid ribonucleic aid and deoxyribonucleic acid. There are four types of nucleotides which make the DNA and these are adenine, guanine, thymine, and cytosine.
Adenine and thymine make complementary base pairing with each other and guanine and cytosine make complementary base pairing with each other in DNA.
In RNA against adenine, uracil comes and against thymine adenine comes. Therefore as at location 2 thymine is present in DNA so in RNA against it adenine will come.

Answer:
1. Bacteria where grow in a medium composed of heavy nitrogen. After several generations the bacteria DNA was composed of heavy nitrogen (heavy nitrogen is an isotope of nitrogen).
2. After several generations had passed, the bacteria were transferred to a nitrogen light medium.
3. As soon as the bacteria were transferred the bacteria DNA was isolated after the first and second generation through centrifugation.
4. Results: after 2 generations half of the DNA was intermediate and half was light; there was not heavy-only DNA. The conclusion was that the new DNA is formed by an "old" strand and a "new" strand producing an intermediate weight.
D.
The temperature won't make a difference since neither mass nor energy can be created or destroyed.
A substance that releases hydroxyl ions in water is a base. Acids on the other hand release hydrogen ions when dissolved in water, while salts release sodium. To define acids and bases the Arrhenius definition is used by scientists---this describes what substances are produce by each type of solutions. Under the Arrhenius definition salt and water can be used to predict the result of the neutralization of an acid with a base.
In Chemistry, Bronsted-Lowry definition has superseded the Arrehenius definition.
False, aerobic respiration creates lactic acid as a by product but produces far more ATP than respiration. When lactic acid is ferment by certain bacteria which includes the bacteria in yogurt and also by human muscles cells when they are worked hard and fast.
In aerobic cell respiration which includes glycolysis + the kerbers cycle = respiratory electron transport that produce 36 ATP /glucose consumed. Aerobic respiration cell are 18 times more efficient than anaerobic cell respiration because in aerobic respiration more ATP than anaerobic respiration due to the complete oxidation of glucose to CO2 and water .
Now O2 acts as terminal electron accept in this electron transport chain and gets reduced to water.ATP are produced by oxidation phosphorylation in the electron transport chain.
