You are curious to know whether the amount of sugar (food) provided to yeast impacts how much waste gas is produced. To help answer this question, you set up an experiment similar to the one you performed in lab. However, this time, you use four flasks instead of two. In Flask 1 you add 1/4 teaspoon of sugar, in Flask 2 you add 1/2 teaspoon of sugar, in Flask 3 you add 1 teaspoon of sugar, and in Flask 4 you add no sugar. You add 1/2 teaspoon of yeast ("unlabeled sample") and 20 mL of lukewarm water to each flask. You place a balloon on top of each flask. After 30 minutes, you measure the circumference of each balloon to determine how much gas was produced efer back to this experiment to answer questions 1-7. ________________ A) What were the treatment groups in this experiment? B) Which group was the control group?
