The sER (smooth endoplasmic reticulum) looks like a folded ribbon and help remove impurities from the cells. Certain cells in the body are responsible for removing more impurities than others. Would you
expect the sER in those cells to be longer and have more folds or shorter and have less folds?

If you were given a map of the sensory cortex in the postcentral gyrus of the cerebrum, do you think the map would have more “space” devoted to the regions of the body that have the highest density of sensory receptors, or the regions of the body that have the lowest density of sensory receptors? explain.
