Answer:
The correct answer will be option-A and B.
Explanation:
Transcription is a process which synthesizes a complementary molecule of DNA which acts a messenger called RNA.
The gene contains a sequence of the nucleotide at the beginning of gene called promoter sequence. The promoter sequence has the ability to attach an RNA synthesizing enzyme called RNA polymerase.
The RNA polymerase is the enzyme which synthesizes the RNA molecules using a single strand of DNA called template strand. RNA polymerase binds nucleotide at 3' end of the strand thus proceeding the strand in 5' to 3' direction.
The promoter and RNA polymerase begins the process of transcription and thus option-A and B is the correct answer.

Answer:
0, 2, 4
Explanation:
The process of cellular respiration takes place in for phases which oxidizes the glucose molecule to the provide energy molecule called ATP.
Along with ATP, the process releases the metabolic water and carbon dioxide gas. In the oxidation of one glucose molecules, about 6 molecules of CO₂ are released. These CO₂ molecules are produced in the following manner:
1. Glycolysis: CO₂ gas is not produced during this reaction but only ATP and NADH are produced.
2. Pyruvate decarboxylation: the process converts the pyruvate produced by glycolysis to Acetyl-CoA. Formation of 1 Acetyl-CoA produces 1 CO₂ and since 2 Acetyl-CoA is produced therefore produces 2 CO₂ molecules.
3. Citric acid cycle: The cycle converts 2 Acetyl-CoA and produces 4 CO₂ in two cycles converting each Acetyl-CoA.
Thus, 0, 2, 4 is correct.
Answer:
D
Explanation:
Control group in an experiment does not receive any treatments. It is used as a benchmark to ensure that there is statistical difference in data between the variables of the control and those with treatments. It also ensures that there are no other overlooked factors that have an influence on the experiment that needed to be considered. Having a control group reduces the chances of erroneous conclusions.
Explanation:
Each liquid falls somewhere along a scale with acid at one end and alkaline at the other. Normally, ocean water is less acidic than fresh water. Unfortunately, as the ocean absorbs more and more carbon dioxide from the atmosphere, it becomes more acidic. Lemon juice is an example of an acidic liquid.
