Yeast can ferment a variety of sugars in anaerobic conditions. Carbon dioxide is produced as a byproduct. A respirometer can be used to determine how much carbon dioxide is produced and thus measure rates of fermentation. Respirometers were set up that contained yeast and either a solution containing a carbohydrate or distilled water. The height of the bubble contained in the respirometer was measured every 5 minutes for 20 minutes. The results can be seen in the graph below. Which tube from this experiment is most likely to contain distilled water & yeast?
