Select the appropriate type of microscopy to perform for a given specimen and experimental question. CORRECT ANSWER viruses-->nanometers e. coli-->micrometers yeast-->micrometers period (on a page)-->millimeters types of microscopy -light: x1000-x2000 mag can't see in much detail, need to stain to see more -TEM: x500,000 mag (exterior; living) -SEM: x500,000 mag (really small; internal struct; dead) labeling techniques -staining: can clearly see struct, kills the cell -...
