Answer:
Hydrogen bonds make water molecules spread out when they freeze. This makes ice less dense than water and allows ice to float. If ice did not float then oceans and lakes would freeze from the bottom up, killing marine life by trapping organisms in the ice. When ice floats, it insulates the water below, keeping it at around 4 degrees C or 40F, which does not freeze and allows fish to survive the winter.

<span>one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.</span>
The process of DNA replication begins with one double-stranded molecule of DNA. The two strands of this molecule separate during replication, and DNA polymerases add complementary nucleotides to each strand. The end results of DNA replication are two identical DNA molecules
The correct answer is option B, that is, functional group.
A functional group refers to a part of a molecule, which is a classified/recognizable group of bound atoms. The functional group provides the molecule with its characteristics, in spite of what molecule comprises it, they are the centers of chemical reactivity. The functional groups in a molecule require to be determined when naming.
