Let's say a geographical barrier separates a species into two different population. Which also cause a reproductive isolation ( the two pupolations cannot interbred)
Throughout the time (lets say a million years), the two populations will undergo a lot of changes in their respective genomes and eventually will form 2 different species.
If there is no reproductive isolation, the 2 population could interbred with one another and there will be no speciation
<em>tRNA brings the complementary base pair to the mRNA already in place. The complementary base pair codes for a certain amino acid. So tRNA does bring the amino acids to the ribosome by bringing the correct code in the sequence to make a protein.</em>

You just got vectored B) uhh I hope someone can help
The correct answer is "plasma cells".
Plasma cells are differentiated or mature B cells capable of producing antibodies against a particular foreign substance. B cells are stimulated to differentiate into plasma cells when it binds to two receptors of helper T cell; having the T cells "help" the B cells to differentiate to plasma cells. These T cells have the antigenic information passed to them by antigen presenting cells such as dendritic cells and these will be passed to the B cells and plasma cells will produce antibodies against this specific antigen.
They could look for similarities in the DNA or protein structuresof the organisms<span> and similarities in early development</span>
