Look at the graphs. Select one pattern/result that interests you. Propose a hypothesis to explain the pattern and propose that below: For example, you might observe a decline in the number of species over time. Maybe there are fewer species at 9 months than you found at 3 months. What could have led to this decline

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.
