Question 7 is D.
Since the NaHCO3 will keep the amount of CO2 constant, and the syringe did not move, the only factor that will affect the pipette reading is the oxygen produced. The volume of gas increased for (0.45-0.20)mL = 0.25 mL in 30 minutes, so the rate = 0.25 mL/0.5 hr = 0.5 mL per hour. 作者: bryanfu926 時間: 2016-4-1 11:55 AM
Question 8 is A.
What the setup measures is the net production of O2, and net production = Oxygen produced in photosynthesis - Oxygen consumed in respiration.
