Question

Assume that a recent study found that a chemical in a popular sports drink could cause a cell to undergo mitosis at an unregulated rate. The researchers concluded that people should not drink this sports drink because it could lead to cancer. Which of the following is a valid response to this conclusion? I. What do chemicals in fruit juices do to cells? II. Which type of cell was used in the study? III. How much of the sport drink chemical were the cells exposed to? A. II only B. I only C. I and III only D. II and III only

Answer 1

The answer is D, II and III. It can depend on how much of the drink the cell was exposed to and what kind of cell it was.

Answer 2

The correct answer would be option D.

I statement would not be a valid response as it is the fact on which the conclusion was made.

On the conclusion provided, one should ask about the cell type used in the study and the amount of chemicals those cells were exposed to.

Different types of cells may response in different manner against a particular chemical. For example, stem cell would response in different manner whereas differentiated cell would response in different manner.

Similarly, the amount or concentration of chemical plays important role in any reaction or cellular response. For example, the affinity of haemoglobin is high towards oxygen in alveoli whereas it is high towards carbon dioxide in body cell.

So, the correct answer would be option D.
