Identify the process used to form the covalent peptide bonds that join amino acids into a polypeptide.

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 carboxylic group of one amino acid and an amino group of another amino acid is linked together with a loss of water molecule or hydrolysis during the process. A polypeptide chain is now then composed of multiple peptide bonds, from binding amino acids (also known as residues at this point), with a linear configuration.

A closer look into this process involves the α-amino group as the beginning of the polypeptide series and ending with the α-carboxyl group. This also serves as the primary structure of the protein.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
