Three Anacharis plants were placed inside inverted test tubes filled with water. One test tube
was exposed to low light, another to medium light, and 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 (in mL) of oxygen
produced between the low-light and high-light plants after 45 minutes?
