The correct answer here is C. Water molecules are more free to move, so they will be able to engage in rapid and fluid contact with magma. This is in contrast to fixed continental rock, which may have quick initial heat transfer but which tapers off quickly because the rock is not flexible enough to send cooler rock towards the magma.
<span>They are composed of similar materials: DNA is a deoxyribonucleotide polymer while RNA is a ribonucleotide polymer. A nucleotide is composed of a nitrogenous base, a sugar, and a phosphate group. In ribonucleotides, the sugar is ribose, while in deoxynucleotides, the sugar is deoxyribose. Adenine, guanine, and cytosine are nitrogenous bases in both DNA and RNA, while thymine is found only in DNA and uracil is found only in RNA.</span>

Answer:
C
Explanation:
A ribonucleotide is very similar to a deoxyribonucleotide with the major difference being that they have a H instead of an OH in the 1’ carbon. Each ribonucleotide also has a phosphate molecule in their 5’ carbon like DNA. It is this phosphate that bonds with the 1’ carbon of the next monomer to form a phosphodiester bond through a condensation process – that releases a water molecule.
