To see patterns in the data from an experiment like this, it is 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.

Explanation:

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.
