There are two sets of lenses in both the compound microscope and the dissecting microscope (also called the stereo microscope).]]> 2021-07-12 05:52:57 UTC https://padlet.com/brandan_lee_yide/Cells163/wish/1645512986 brandan_lee_yide https://padlet.com/brandan_lee_yide/Cells163/wish/1660802232 2021-07-26 05:47:33 UTC https://padlet.com/brandan_lee_yide/Cells163/wish/1660802232
