A scientist wants to distinguish two ribosomes that are 25 nm apart in a cell. The scientist also wants to observe living cells of the same type changing over time.
| Microscope | Type | Shortest distance that can be resolved |
|---|---|---|
| L | Light microscope | 200 nm |
| E | Electron microscope | 0.8 nm |
Explain which microscope the scientist should use to distinguish the two ribosomes and why the scientist cannot complete both parts of the investigation using this microscope.
