With chemistry pls you why are the amino acid sequences his—gly—ala and ala—gly—his chemically different from each other? a. the free amino group and carboxylic acid group are located on different amino acids. b. the two sequences are composed of different atoms and have different molar masses. c. one sequence is a tripeptide; the other sequence is a triglyceride.

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
