Through random genetic mutations of a species over time, beings with unique characteristics emerged. Based on the suitability of the adaptation to the environment, the beings would either be able to successfully reproduce, or not, and perish. Successful adaptations would be passed down to children, resulting in the adaptations persisting at least in the short term. Charles Darwin is an excellent author to study to learn more about the theory of evolution.</span>
Answer:
The correct answer is nitrogen base
Explanation:
The nucleotide sequence of one codon differ from that of another codon by the presence or absence of specific nitrogen base.The nucleotide sequence of different codons contain different nitrogen bases.
As a result change in genetic code result from the change in the nitrogen bases of the codons present in the genetic code.
In simple words change in single nitrogen base of a codon will change the entire codon.
<span>The carbon dioxide level in the city will be higher because the exhaust gases from vehicles release carbon dioxide and there are not many trees to utilize it.
Plants go through photosynthesis using carbon dioxide, releasing oxygen in the process, so more of the carbon dioxide is used in the garden. Plus, there is more carbon dioxide in the city to begin with, simply because there are more vehicles with more exhaust.</span>
