Ascientist examines a bacterium and learns that it carries a gene that makes it resistant to antibacterial medication. because bacteria reproduce through , it’s likely that of the offspring created by bacteria with this gene will be resistant to the medication.

The offspring created by bacteria with this gene will be resistant to the medication. The reason is that the bacteria reproduce by binary fission. If anyone carries a gene which makes it resistant to antibacterial medication.

Then its offspring will be resistant because in binary fission, DNA replicates and seperate. DNA replicates which possess the gene which makes it resistant to antibacterial medication then offspring will have that DNA which possesses such gene. Binary fission is a type of asexual reproduction.

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.
