The options are :

A) phosphate

B) nitrogen

C) guanine

D) uracil

E) thymine

Answer:

The correct answer is E) thymine

Explanation:

DNA and RNA are both made up of nucleotide. There are two major difference between DNA and RNA. In DNA deoxyribose sugar is present and in RNA ribose sugar is present.

The other difference is in DNA thymine nucleotide is present which makes complementary base pairing with adenine but in RNA thymine is replaced by uracil.

Therefore testing for the presence of thymine is most appropriate in this situation to find out whether a nucleic acid sample is composed of RNA or DNA.

3. jack is using plastic beads to model water molecules in each state of water. how shoule she the beads to represent water mole
just olya [345]

Jack should arrange the beads close together and slide past each other to represent water molecules in a liquid.

<h3>How are the molecules of water arranged when water is in its liquid phase?</h3>
  • Each water molecule contains two atoms of hydrogen and one atom of oxygen, arranged such that one side of the molecule (nearest the hydrogens) is positively charged while the other side (nearest the oxygen) is negatively charged.
  • They’re arranged randomly, and in random motion.
  • In fact, they’re not even keeping the same hydrogen atoms, as they are constantly popping off and reforming on the nanosecond time scale.
