Why it is better to have two test tubes with yeast sugar and water and two test tubes with just yeast and water instead of only one test tube with each type of mixture?

Having two test tubes with yeast, sugar, and water, and two with just yeast and water allows for better control of experimental variables and the ability to replicate results. This setup enables comparison between the two conditions, helping to clearly assess the impact of sugar on yeast activity.
