Answer: invivo
A person has a genetic condition that affects his ability to produce melatonin, which is a hormone that is produced in the brain and tells the body it’s time to sleep. To correctly diagnose this disease, the doctor must collect cell samples invivo to analyze his DNA.
Explanation:
Invivo refers to the within the living organism. Since DNA is located inside the nucleus of brain cells, and it regulate gene expression; then the doctor must analyze the genetic information contained in the DNA of brain cells of the person having trouble with secreting melatonin ( the sleep/wake hormone), if any alteration has occurred.
Thus, based on the location of DNA, the doctor must collect cell samples invivo for analysis

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'.
