The difference between an artery and a vein is that arteries are larger, more muscular and more elastic than veins; they carry blood that is under pressure from having been pumped out of the heart; veins are under much less pressure, so they are not as strong
Answer:
See the explanation below, please.
Explanation:
The amino acid sequence of a protein will determine the interactions inside and with the environment (that is, it will influence the conformations that are adopted at physiological temperature: the degrees of freedom). Example: the proline amino acid (Pro) has a cyclic structure, which implies a limitation in the random movement of the polypeptide chain.
In proteins, the primary structure determines the sequence of the amino acid sequence of the polypeptide chain (amount of amino acids present and their order by means of peptide bonds).
Cells because all living organisms have cells
Answer:
Plant cells have a cell wall, but animals cells do not. Cell walls provide support and give shape to plants. Plant cells have chloroplasts, but animal cells do not. ... Plant cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles, if any are present.
