<span>The correct answer is A. atoms. Atoms are studied by physics and chemistry, not by ecology. Ecology studies organisms, populations, and the earth in terms of climate, pollution prevention, natural habitats and biomes, and all kinds of similar things that are related to living on earth. Atoms are irrelevant for the study of ecology.</span>

<em>Electron microscope </em><em>is most likely to be used to produce a clear image of very tiny structures inside a cell</em>
Answer: <em>B. Electron microscope</em>
Explanation:
The electron microscope is a kind of magnifying instrument that utilises electrons to make a picture of the objective. It has a lot higher amplification or settling power than a typical light microscope. The tiny structures inside the cell are easily visible under the electron microscope. 
The electron microscope can be scanning electron microscope or tunnelling electron microscope. Both the type of electron microscopes differ in function but uses electron as its source of illumination.
