Proteins some amino acids (monomer of protein) will get broken down for energy via cellular respiration
Hope this helps!
The frequency of allele T would decrease and the frequency of allele t would increase.
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.

<span>The lac operon has three genes that encode for proteins that break down lactose into galactose and glucose. When there is no lactose around, it wouldn't make sense for the prokaryote to make these proteins as it would be a waste of energy. So, when there is no lasctose around, the lac repressor binds the operator region of the operon, which inhibits RNA polymerase's ability to bind and start gene expression. However, when lactose is available, it binds to the lac repressor and deactivates it via allosteric inhibition. Once the lac repressor is gone, the genes can be transcribed into mRNA which can be translated into proteins which can go and break down the lactose. </span>
I believe that the answer is autotrophs
