The rocky material left behind by a retreating glacier forms what is called a moraine. When primary succession occurs on a moraine, which life forms will help create the soil by breaking down bare rock?

Protein and polypeptide sequences can be determined by first partially hydrolyzing the protein or polypeptide followed by amino acid sequencing of the fragment pieces using the chemical degradation process known as edman degradation. determine the sequence of the initial (18-amino acid) polypeptide that produces the following five partial sequences after hydrolysis and edman degradation.
