Hello!
There are two possible answers to this. The one I'm assuming you're looking for is hydrogen bonds.
Hydrogen bonds are the bonds which hold together the double helix shape of DNA. These bonds result from a positive and negative charge drawing two molecules closer to each other. These bonds are generally seen as weak, however, since there are so many of these bonds (as there are so many nitrogenous bases in one strand of DNA), the double helix strand is fairly strong.
Hope this helps!
Answer:
A
Explanation:
You have to repeat it to see which result you see more of, because that would most likely be the correct solution.
To clearly view the morphology of the prokaryotes, one needs a microscope with higher resolution i.e magnification of ×100. Use of oil for this purpose is important because it reduces the refraction of light as it travels from air to glass. this process increases the resolution of the microscope making it possible to view morphology of bacteria.
