Mr. Miller's biology class is studying cellular respiration. To model cellular respiration, they set up an experiment containing four flasks. Each flask is the same size and are stoppered and placed under a floodlight. Each flask also contains 200 mL of H20 and 2 mL of bromthymol blue. Bromthymol blue is a chemical indicator solution that changes color from blue to yellow in the presence of CO2. The students then place a vary placing a plant and fish into each flask according to the table above. Which flask(s) will turn yellow and why?
