'''9.''' At the first time point, the cell density is very low. Consequently, there is no appreciable depletion of the source of glucose. Since there is no stress present, as there would be if the availability of glucose was significantly decreasing, most of the genes are not being induced or repressed. Thus, most of the spots are yellow. | '''9.''' At the first time point, the cell density is very low. Consequently, there is no appreciable depletion of the source of glucose.
