Anew bactericidal antibiotic, brooklamycin, has a miminum inhibitory concentration of 1 nm (nanomolar). if you use that concentration of streptomycin to kill 10^9 bacterium in 1 ml, how many molecules of the antibiotic are necessary to kill each cell?

the function of the protein macromolecule is to move things in and out of the cell and transport other molecules in the body. there are many functions of proteins. they are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues.

explanation:

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.

all matter is made up of atoms

in any element all atoms are the same

elements in a compound are always in a constant ratio: apex
