Emigrated means they exited so due to the high amounts of pollution all the animals left which cause a population decrease
Well silly we would all be dead if it wasnt bonded right
Answer:
Peptide bonds and Amino Acids
Explanation:
Primary structure. The primary structure of a protein refers to the sequence of amino acids in the polypeptide chain. The primary structure is held together by peptide bonds that are made during the process of protein biosynthesis.
Cellular structures and lifestyles
are much diversified.
In spite of these differences, the same basic molecular mechanisms govern the
lives of both prokaryotes and eukaryotes,<span> the general classes of
proteins involved in signal transduction are conserved all over living cell. This is manifested through the
re-used of protein receptors, protein kinases,<span> phosphoprotein phosphates, and ion channel receptors.</span></span>
A) Natural selection
Hope this helps I took bio ;)
