Data Representation: Gel Dye Diffusion Plates. Gelatin plates were poured with two gel concentrations. For each concentration, wells were filled with red dye, blue dye, or green dye. Plates were covered and kept level for 40 minutes before the dye fronts were traced. Researchers recorded diffusion distance from each well. A planned ACT Science-style visual summarizes the group layout or sequence. Which summary would accurately appear in the methods section?
