Solution Steps

Step 1: Identify the tube with the least bubble height
  • The tube with the least bubble height over time is Tube E.
Step 2: Determine the contents of the tube with the least bubble height
  • Since Tube E has the least bubble height, it is most likely to contain distilled water + yeast, as there is minimal fermentation and gas production.
Step 3: Identify the tube with the highest bubble height
  • The tube with the highest bubble height over time is Tube A.
Step 4: Determine the contents of the tube with the highest bubble height
  • Since Tube A has the highest bubble height, it contains the carbohydrate that is fermented most efficiently by the yeast, resulting in the most gas production.

Final Answer

  1. The respirometer most likely to contain distilled water + yeast is Tube E.
  2. The respirometer that contains the carbohydrate fermented most efficiently by the yeast is Tube A.
