Blood pressure is determined by:. A. estimating the degree of turbulence in a partly closed vessel. B. listening carefully to the pulse. C. measuring the size of the pulse. D. estimating the pressure needed to close off an artery with an external pressure cuff. E. measuring the force of contraction of the left ventricle.

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.
