Imagine that you are able to collect several 1 mm3 samples from the kidney and the brain of a lab rat. If you were to look at the microscopic organization of these two organs, what kind of cells would you expect to find in each sample? Would you expect to find similar cell types between the two organs? What would those cells be, and what structures would they form?

Make a drawing illustrating your analysis in part a. Draw cells with their relations and include labels to identify them.
