Your lab team mixes dry baker’s yeast with warm water and divides the mixture between two test tubes. You add 5 grams of sugar to one test tube but nothing to the other tube. A small balloon is placed over the mouth of each test tube. After 30 minutes your team records the following observations. Yeast and warm water: The water is cloudy after a minute. After 30 minutes the yeast is settled to bottom of tube, water is less cloudy.

Yeast, warm water and sugar: Thewater is cloudy, a few bubbles have formed on top of the water. After 30 minutes the water is cloudy, lots of bubbles in the test tube, balloon has inflated some.
