Biology

An experimental design was set up by biology students to observe cellular respiration by aerobic bacteria in a closed culture. a measured amount of glucose was added to the culture at the beginning of the experiment with no subsequent glucose added later. the students measured carbon dioxide and oxygen levels using electronic probes. the initial oxygen level was 600 parts per million (ppm) and the initial carbon dioxide level was 120 ppm. which data is consistent with the process of cellular respiration occurring by the bacteria in the culture if tested one hour after the initial reading in the experiment? a) oxygen- 720 ppm carbon dioxide- 80 ppm b) oxygen- 600 ppm carbon dioxide- 120 ppm c) oxygen- 200 ppm carbon dioxide- 520 ppm d) oxygen- 800 ppm carbon dioxide- 720 ppm
