S. pyogenes is a gram-positive bacterium. gram-positive bacteria have structural differences that distinguish them from gram-negative organisms. of particular interest to this case is the fact that these differences in structure can be exploited during treatment.

The method may be easily applied in order to obtain additional information for clinical prescriptions from. By new method, we could easily distinguish gram-positive and gram-negative bacteria in liquid culture media within 10 min. This modest and fast technique may be beneficial for determining the treatment course of patients with UTIs, particularly for those without a prior history of UTIs.

answer; i believe that the correct answer is (lung);

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
