Which Microscope Would Be the BEST Selection for Examination of a Virus

Question

Which microscope would be the BEST selection for examination of a virus?
A) Confocal scanning laser microscope
B) Scanning electron microscope
C) Dark-field light microscope
D) Atomic force microscope
E) Compound light microscope

Accepted Answer

The scanning electron microscope (SEM) is the best selection for examining viruses because it provides high magnification and resolution, allowing for detailed imaging of virus structures. Additionally, SEM can be used to investigate the surface morphology of viral particles, which is important in distinguishing between different virus types. The other microscopes listed may be useful for other types of microscopy, but they are not as well-suited for virus examination as the SEM.
