Read this paragraph from the section "Studying Space Microbes." A new study of the life forms, or organisms, living on the space station found that there are more types of life living there than there are in the carefully controlled rooms at the Jet Propulsion Laboratory on Earth. JPL is a government-funded space research center. The researchers also detected some tiny types of life on the station, or microbes, that could be harmful to human health.

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 electromagnetic energy from the sun arrives in the form of visible and invisible light.
