Which is a disadvantage of using an electron microscope rather than a light microscope?
The specimen must be dead, so living processes cannot be observed
The specimen must be stained, so some structures cannot be seen at all
The magnification is fixed, so the size of the image cannot be changed
The resolving power is low, so the smallest structures look blurred
