Correct Answers
amino acids - ANSWER-form the building blocks of protein; link
together end to end like pop beads by strong, chemical peptide bonds
(end bonds) to form the polypeptide chains that comprise proteins
.anagen phase - ANSWER-also known as the growth phase; hair phase
during which new hair is produced
.arrector pili muscle - ANSWER-Causes hair to stand on end and goose
bumps to appear
.catagen phase - ANSWER-brief transition period between the growth

the bulb (plural: dermal papillae)
.disulfide bond - ANSWER-strong chemical side bond that joins the
sulfur atoms of two neighboring cysteine amino acids to create one
cysteine, which joins together two polypeptide strands like rungs on a
ladder
