Question

To study the details of protein molecules on the surface of a cell, a biologist would likely use a

scanning electron microscope

transmission electron microscope


compound light microscope

dissecting microscope

Answer 1

To see things on a molecular scale, the biologist will need to use a microscope with the finest possible resolution which rules out the compound light microscope and the dissecting scope. That leaves two options. Of those two it's more likely to be the one which scans along surfaces.

Hope that's helpful.
