Which of these statements is not true with regard to the process of evolution? O A. It explains the differences in living organisms. B. It has been observed in populations of living organisms. O O C. It results in gradual change over time. D. It happens only when organisms need to change.

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.

the answer is a) cell division.

hope this !

the answer is c a tornado
