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. Answer the question just as the peptide fragments are represented. Be sure to put a hyphen between each three-letter amino acid designation, and be sure to capitalize the first letter of each residue.
A. Gln-Phe-Val
B. Gly-Asn-His-Leu-Lcu
C. Phe-Val-Met-Pro-Pro
D. Leu-Leu-Asp-Glu-Cys-Gln
E. Pro-Pro-His-Ser-Gly-Ala

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

explanation:

2b2t

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
