Astudent set up an experiment to show that carbon dioxide is produced by elodea plants during photosynthesis. she filled two test tubes with distilled water and placed a piece of elodea in each of the tubes. she added a drop of phenol red, which turns red in a basic solution and yellow in an acidic solution. she blew in each tube to add carbon dioxide, which caused the distilled water to become more acidic so the phenol red turned yellow. she wrapped tube a in aluminum foil and left tube b exposed to the light. after 15 minutes, what should she expect to observe?
