C) RNA<span> carries the code from DNA in the nucleus to the ribosome for protein synthesis.
The ribosomes are in the cytosol/cytoplasm, but DNA is in the nucleus. DNA is too large to travel out of the nucleus, so it needs the help of mRNA to transfer the genetic code to the ribosome, which translates the code into a protein. That means A, B, and D cannot be true. </span>

Answer:
Scientist 1
Explanation:
<em>The conclusion of scientists 1 is valid.</em>
Human activities such as burning of fossil fuels, agriculture, deforestation, etc. leads to the emission of carbon in the form of carbon dioxide into the atmosphere. <em>An increase in the population of a city will only lead to an increase in these activities and hence, an increase in the amount of carbon emitted into the atmosphere.</em>
Also, volcanic activities leads to the production of volcanic gases which is a mixture of carbon dioxide, oxides of sulfur, nitrogen, etc.
<u>However, an active volcano that is several miles away from the city might not be a major source of carbon in the air above a large city. The carbon dioxide produced from such volcanic activity thins out before reaching the city.</u>
