Light microscope<span> uses </span>light<span> to illuminate specimens and glass lenses to magnify images whereas an </span>electron microscope<span> uses a beam of </span>electrons<span> to illuminate specimens and magnetic lenses to magnify images.
The resolution of electron microscope is very high is compared to that of light microscope. It means, for very small objects like nucleus of cell, virus, we can use electron microscope instead of light microscope.
Hope this helps!

The answer to this is NATURAL SELECTION. From the given scenario above, this is classified to be a natural selection because of the changes made by the individuals in order to adapt the presence of this fungal disease. When we say natural selection, this is the ability of an organism to adapt to a certain environment in order to survive. This is according to Charles Darwin which has been the source for the study of evolution.
Answer:
Space constraints.
Explanation:
Space constraints are the energetic constraints that prevent prokaryotes from getting larger than their limit. Space constraints control the sizes of both the largest and smallest bacteria. Bacteria can't shrink more than they have already because there is not enough space left for DNA and necessary proteins. In the same way, the prokaryotes can't increase in size beyond their limit due to space constraints.
The answer should be a covalent bond.
