A student sets up а phоtоsynthesis experiment using twо identicаl test tubes, eаch containing an aquatic plant and a carbon dioxide indicator solution (bromothymol blue). The tubes are left for 6 hours under the following conditions: Tube 1: Placed in bright light Tube 2: Placed in complete darkness Initial pH of both solutions: 6.0 After 6 hours, the student records the following pH readings: Tube 1: pH 7.5 Tube 2: pH 5.5 What is the best explanation for these results? A) Tube 1 absorbed more water, which caused the indicator to become more basic.B) Tube 2 produced more oxygen, increasing the pH of the solution.C) Tube 1 carried out photosynthesis, removing CO₂ and raising the pH.D) Tube 2 continued cellular respiration, increasing CO₂ and lowering the pH.
