Three Anacharis plants were placed inside inverted test tubes filled with water. One test tube was exposed to low light, another to medium light while another was exposed to high light. The table provided shows the results of this experiment. Notice that more oxygen was produced by the Anacharis in high light. Based on the information provided, what is the difference in volume of oxygen produced between the low light and high light plants after 45 minutes? Record your answer in the grid provided.

• 1.1 mL

• 3.9 mL

• .6 mL

• .5 mL
