Capillaries are very thin, narrow blood vessels that allow for the transfer of oxygen, carbon dioxide, and nutrients. The image shows how normal red blood cells and sickle-shaped red blood cells flow through a capillary,
Use information in the image to describe two ways that the sickle cell gene mutation affects the ability of red blood cells to perform
their normal function

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.
