Coral bleaching results when the symbiotic zooxanthellae, a single-celled algae, are released from the original host coral organism due to stress. when the zooxantheallae are released, the coral loses its pigment, resulting in a bleached or completely white appearance. the most common cause of coral bleaching is

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.
