<span>B is the correct answer. The beginning of DNA replication occurs with the unwinding of the DNA helix by a special enzyme. The two strands that form the helix then create a replication fork. The two strands are then oriented differently, one becoming the 'leading strand' and one the 'lagging strand'. </span>
Answer:
Anaerobic respiration or fermentation
Explanation:
The metabolic pathway shown in the question is the summary of anaerobic respiration (fermentation) during which pyruvate is converted to acetaldehyde, followed by the formation of alcohol (ethanol), along with the release of NADH and NAD molecules. This mechanism occurs in the absence of oxygen and is thus used by organisms to generate energy (ATP) molecules.
Answer:
Colors are assigned to different reflected bands electromegnetic waves.
Explanation:
Glucose is converted into Pyruvate
