Someone helpp me pls :(((

Explanation:

This shows that in 2018 the number of nests increased while the number of eggs per nest increased at the minimum and decreased at the maximum when compared to 1780. We can see that by looking at the graph. The blue curve represents 2018 and the dotted 1780. The Y-axis represents the number of nests while the X-axis represents the number of eggs. The dotted one is shorter but wider and the blue one is taller.

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.
