3) number of seeds and 4.) stem length
Answer:
Two amino acids are joined together by losing a water molecule, or hydrolysis.
Explanation:
A peptide bond is formed by binding two or more amino acids. This is a kind of covalent bond, wherein the <u>carboxylic group</u> of one amino acid and an <u>amino group</u> of another amino acid is linked together with a <u>loss of water molecule or hydrolysis during the process</u>. A polypeptide chain is now then composed of multiple peptide bonds, from binding amino acids (also known as <u>residues</u> at this point), with a linear configuration.
A closer look into this process involves the <u>α-amino group as the beginning</u> of the polypeptide series and <u>ending with the α-carboxyl group</u>. This also serves as the primary structure of the protein.
The cell requires a barrier between itself and its environment.
