The most appropriate microscope for studying the internal parts of the cell is ELECTRON MICROSCOPE. The correct option is B.
Electron microscope, which is a compound microscope is usually used to study the internal environment of the cell because of the easiness with which one can easily distinguish the cell organelles from one another. Electron microscope gives great clarification of the cellular components and allow scientists to observe minute details about cellular structures. Electron microscope usually magnify specimens to one million times of their real sizes.
Nonpoint source pollution is a greater hazard, because scientists are not able to identify a single location the pollution came from. It is harder to find a solution if they are unable to find the source.
Hope this helps!
have a great day.
