It is the difference in the r group that makes each amino acid chemically unique. it is the difference in the r group that makes each amino acid chemically unique. a. true b. false

True

Explanation:

The amino acids can be defined as organic compounds that is composed of oxygen, nitrogen, carbon and hydrogen.

The body has 20 different types of amino acids in the body of the organism. The amino acids are characterized based on the difference in their alkyl groups that is found in it.

The amino acids consists of a carboxyl group, amino, hydrogen and alkyl group. Rest of the structures remains same but the change in the alkyl group makes one amino acid different from other.

mechanics (greek   is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.
