A researcher needs to distinguish two points that are 100 nm apart in a living yeast cell.
The table shows information about two microscopes.
| Microscope | Shortest distance between two points seen as separate | Can be used to view living cells |
|---|---|---|
| Light microscope | 200 nm | Yes |
| Electron microscope | 0.5 nm | No |
Which statement best evaluates the suitability of the two microscopes?
Use neither: the light microscope cannot view living cells, and the electron microscope cannot separate points 100 nm apart.
Use the electron microscope: it can separate points 100 nm apart, and it can view living cells.
Use the light microscope: it can view living cells, and it can separate points 100 nm apart.
Use neither: the light microscope cannot separate points 100 nm apart, and the electron microscope cannot view living cells.
