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 bromothymol blue. bromothymol 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?

Flask 2 only;

Reason; Because the fish produce CO2 as products of cellular respiration and do not undergo photosynthesis therefore not consuming CO2.
