<span>In order to determine the sugar molecule associated with the nucleic acid, we must first determine if the nucleic acid is a deoxyribose nucleic acid (DNA) molecule or a ribonucleic acid (RNA) molecule. We can determine this by looking at the bases in the molecule, as DNA has thymine and RNA has uracil. After the type of molecule is determined, the nature of the sugar is given by the name. DNA has deoxyribose and RNA has ribose</span>

Answer: <u>Option 4; Oxygen gains electrons and hydrogen to form water.
</u>
Respiration is a process where glucose is used and energy is released stored in this molecule. Oxygen is used during respiration as well and it gains the electrons and hydrogen to form water. And, gain of electrons is an oxidation reaction. So answer is option 4.
Since, oxygen is consumed during respiration, option 1 is incorrect.
Loss of electrons is reduction, so option 2 is also incorrect.
Glucose is used in respiration, thus option 3 is incorrect.

Explanation:
According to the research, a molecular clock can be used to determine the number of differences in a specific DNA sequence of two species (c).
<h3>What is a molecular clock?</h3>
It is a tool that allows us to relate the divergence time or the time elapsed since the divergence of two current lineages from their common ancestor.
It is based on analyzing and comparing the genetic material of organisms to establish the number of mutations.
Therefore, we can conclude that a molecular clock can be used to determine the number of differences in a specific DNA sequence of two species (c).
