Answer: Option A) Double-stranded DNA
Explanation:
First, the presence of thymine infers that the genome is DNA.
Then, to determine whether it is single or double stranded, we check if the sum of all nitrogenous bases is equal to 100%
A + C + G + T = 100%
28% + 35% + 20% + 17% = 100%
Since all bases makes 100%, we can conclude that the genome is a double stranded DNA
<u>Answer:</u>
<em>Hydrogen and ozone are both examples of trace gases.
</em>
<u>Explanation:</u>
Trace gases are present in minor quantities in the <em>earth’s atmosphere and all the gases except nitrogen, oxygen and argon </em>which make up the major portion of earth’s atmosphere are considered trace gases.
The respective percentages of nitrogen, oxygen and argon in the atmosphere are<em> 78.1%, 20.9% and 0.934%.</em> The process that produce trace gases is called source and the process that removes trace gas from the <em>atmosphere is called sink.
</em>
<em>Some other examples of trace gases are carbon dioxide, neon, helium etc.
