For this activity, you can upload an Excel file with your Tetrahymena data, and visualize the data with different types of graphs. When you create your Excel file, name the first column Ratio, the second column Nuc_Diam, and the last column Cell. You can then click on the next tab Activity and upload your data. On the last tab, you can provide feedback. However, I have not hooked it up yet (so you will have to complain to me via email).
You need to think hard to answer this question.
