Refer to the description and table below to answer the three question that follow: Dissolved oxygen levels from 3 bottles of algae were recorded. The DO level of bottle #1 was recorded immediately after the algae was collected, the DO level of bottle #2 was recorded after sitting for 20 hours wrapped in tin-foil, and the DO level of bottle #3 was recorded after sitting for 20 hours under a lamp. A heat sink was placed over all of the bottles to ensure that temperature did not have an effect on the results. The following data was collected: Bottle Number D.O. Level 8 #1 #2 1 #3 6 4. How many units of oxygen were used for cell respiration by the algae? d. -2 a. 7 b. 2 c. 5 e. -5
