Im confused in BIO Destroyer #248, are there two types of cell-surface components in the diagram or one? In the question it asks what structure is in the diagram, but in the answer it says desomosomes are in the picture....and then later says gap junctions are in the diagram. The answer was gap junction, yet it says desmosomes are in the picture too, so are they both in the picture or is destroyer referencing something that isnt there?
