What functional groups will be joined together if alanine and serine molecules combine to form a single molecule?

(a. an amino group and a carbonyl group.)
(b. an amino group and a methyl group.)
(d. a hydrogen atom and a methyl group.)

The correct answer is a an amino group and a carboxyl group.

Explanation:

Alanine and serine are both amino acids.Alanine is a simple amino acids where serine is a hydroxyl amino acids.

      When alanine and serine molecules combine to form a single molecule at that time an amino group and the carboxyl group will be joined together to form a ala-ser peptide linkage.

the peripheral nervous system or pns contains the nerves, which leave the brain and the spinal cord and travel to certain areas of the body. the peripheral nervous system's main job is to send information gathered by the body's sensory receptors to the cns as quickly as possible.

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.
