Kidney preserve or excrete H⁺ ion and HCO₃⁻ ion to regulate the blood pH.
I think zoe because you can’t just test which one is the best it’s too broad to investigate
What? I don’t understand?
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.

I think it’s most likely option B
