forensic science is like realistic fiction so they link together because of their genera.
1.) their wavelengths must be short i think and 2.) High frequency waves travel 3.) True
The answer (although it appears to be missing a word or two) is:
C) The cell would have to take in and use (energy, resources) in order to break the covalent bonds.
Covalent bonds are more difficult to break/create than hydrogen bonds, and thus require more energy. The advantage of hydrogen bonds to connect base pairs in a DNA strand is the ease with which they can be broken and then connect again, sort of like a zipper. The same process with covalent bonds would be more like unbuttoning and re-buttoning a shirt, it is slower and requires more energy to accomplish.
