Hypothesize why some of the sugar or sweetener solutions were not metabolized, while others were. research the chemical formula of equal® and splenda® and explain how it would affect yeast respiration.

Interestingly, while yeast cannot metabolize artificial sweeteners like Equal, many of these sweetener packets contain small amounts of real sugars (dextrose) as a stabilizer, and so the balloons will inflate a little bit when the artificial sweeteners are used-- this is a very surprising result

the darker peppered moth species were favored due to the fact that the industrial revolution had made all the nearby trees a darker color instead of white.
