Aflask containing photosynthetic green algae and a control flask containing water with no algae are both placed under a bank of lights, which are set to cycle between 12 hours of light and 12 hours of dark. the dissolved oxygen concentrations in both flasks are monitored. predict what the relative dissolved oxygen concentrations will be in the flask with algae compared to the control flask. the dissolved oxygen in the flask with algae will
