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>
Carbon and nitrogen and an important element of living things. Nitrogen is a major component of DNA and amino acids while carbon can be found in almost all biomolecules. These elements, therefore, need to be renewed and recycled as they are utilized by ecosystems that is ever dynamic.
RNA: AUGGUACCUUAAUGA
A=U (in RNA only. T in DNA)
C=G (in both DNA and RNA)
