Which of the following do you find in prokaryotes, eukaryotes, and viruses?

a
all are living
b
DNA/RNA
c
all are non-living
d
ribosomes

b. DNA/RNA

Explanation:

Prokaryotes, eukaryotes, and viruses are composed of DNA or RNA molecule. DNA is a molecule which contains genetic information about growth, development, functioning and reproduction of all living organisms. Prokaryotes are organisms which have no true nucleus while eukaryotes have true nucleus. True nucleus means membrane present around the nucleus. Virus is the only organism which is considered as both living and non living.

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.

that is wrong, its not thymus.
