Include your hypothesis for this experiment. Be specificâ¦in other words we sure to include at least one end point you will measure to support your predictions. Natural sugar causes fermentation by producing CO2
Did you notice a difference in the rate of respiration between the sugars? Did any of the artificial sugars provide a good starting material for fermentation? Yes no artificial sugar did not provide a good starting material for fermentation as there was no change in height of gas.
Which tubes displayed evidence of anaerobic fermentation? How did you know? Due to change in gas height we can determine fermentation was occurring during to production of CO2
