Answer:
The correct answer is option e. "that the protein being studied does not contain disulfide bonds in its quaternary structure".
Explanation:
Reducing agents, such as ß-mercaptoethanol (BME) or dithiothritol (DTT), are elements or compounds that break down disulfide bonds. These agents reduce the disulfide bonds and prevent the oxidation of the thiol groups of the cysteine residues that form the disulfide bonds. If one protein that was not treated with a reducing agent have the same electrophoretic behavior than a protein that was treated with a reducing agent in a SDS-PAGE experiment, then the results most likely indicate that the protein being studied does not contain disulfide bonds in its quaternary structure.

Genetic drift is a process in which allele frequencies within a population change by chance alone as a result of sampling error from generation to generation. Genetic drift is a random process that can lead to large changes in populations over a short period of time.
Smoking have life-threatening effects on a smoker's lungs. A smoker is at a high risk of lung cancer and chronic obstructive pulmonary disease. In order for a coach to explain the destructive effects of smoking on the performance of the athletes, it is best to show a diagram of the flow of the oxygen-rich blood in a non-smoker's body and then the flow of blood with less-oxygen in smoker's body. This will show the difference between the two situations clearly, and show how the airway resistance effects the performance of a person.
Hence, the answer is 'option C - Diagram the flow of oxygen-rich blood in non-smoker's body and the, diagram of flow of blood with less oxygen in smoker's body'.
