Amino acids can be distinguished from one another by a) the number of r groups found on the amino acid molecules. b) the chemical properties of their r groups. c) the type of bond between the r group and the rest of the amino acid molecule. d) the chemical properties of their amino and carboxyl groups. e) the number of alpha carbons present in the amino acid molecules

The answer to your question is: letter B

Explanation:

A) the number of R groups found on the amino acid molecules.  The number of groups R is not consider to distinguished amino acids, they only have 1 R group so this answer is incorrect.

B) the chemical properties of their R groups. This is the right answer because of the chemical properties of R groups them will be the kind of reactions an amino acid have.

C) the type of bond between the R group and the rest of the amino acid molecule. The type of bond is not important most of them have the same bonding. This answer is not correct

D) the chemical properties of their amino and carboxyl groups. All amino and carboxyl groups have the same properties. This answer is not right.

E) the number of alpha carbons present in the amino acid molecules. This is not important so this answer is not correct.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
