Q 1. Which of the respirometers serves as control? Give reasoning why the respirator you selected serves as a control.2. Assuming your experimental control measures worked, identify what variable(s) changed to bring about the observed change in volume (corrected change in volume in Table 1 and Table 2) and explain why in detail? You must include in your explanation: oxygen, carbon dioxide, and KOH. 3. Explain your results in detail from your data table using numerical data (if your experiment did not work, feel free to use the sample data.) Compare the numerical results from the respirometers containing germinating and dormant peas.
