Microevolution is small genetic changes within a specific population or a group within a population, occurring within a short time span, like one generation. Macroevolution is big changes across species and over long spans of time.
Mostly yes so I have to be as good as possible
Most likely it's B. The fossil record provides samples of every organism that ever lived.
Answer:
2 base long codon
Explanation:
In the given question, the total number of amino acids is about 10 and the number of nucleotide bases is only two.
So these two nucleotides will be arranged in a maximum of 
as there are only two nucleotides and either each nucleotide will code for a single amino acid or in pairs of two it will code for specific amino acids. Therefore the maximum amino acid chain will be formed by the four bases of amino acids.
Thus, 2 base long codon will be correct.
A chemical reaction was the cause of that particular event
