To see patterns in the data from an experiment like this, it is helpful to graph the data. A bar graph is used instead of a line
graph because each type of liver cell was independent of the others. But first, you must determine which variable should go on each axis of the graph. What variable did the researchers intentionally vary in the experiment, and what are the units for this variable?
From the information you provided, the information intentionally varied is the type of liver cells and there should not be any units for this variable unless the liver cells were categorised by a quantitative feature. The y axis would be the axis of the dependent variable measured and the x axis would be the axis of the independent variable measured.
