Species A and B have fewer differences between DNA sequences means that fewer mutations occurred. It is likely due to sequence homo-logy.
<h3>Whta are mutations?</h3>
A mutation is any alteration in the nucleotide (DNA) sequence of the genome of a particular organism.
The linear order of nucleotides and their differences (mutations) can be used to infer homo-logy between two species.
In this case, there are only two different nucleotides in these sequences, thereby sequence homo-logy indicates a likely common origin.

Answer:
By comparing the observed and modeled patterns, scientists can positively identify "human fingerprints” and attribute a proportion of observed warming to human activities. These fingerprints are found in a diverse range of records from the atmosphere, the ocean, and Earth's surface
Only so many can fit in the area meaning the vain ,artery or somthing else
Step 1
Copy of one side of DNA strand is made (called mRNA, messenger RNA)
Step 2
mRNA moves to cytoplasm, then ribosome
Step 3
mRNA goes through ribosome 3 bases at a time
Step 4
transfer RNA (tRNA) matches up with the open DNA bases
Step 5
tRNA releases the amino acid at the top, which joins the chain of amino acids being produced
