Use the graph to choose the three true statements.

The term "flu season" is misleading as there are equal numbers of deaths from the flu throughout the year.
This graph is consistent with an unusually highly contagious strain of influenza circulating in 2009.
Summer and early fall typically have lower flu mortality than other times of the year.
The timing of next year’s flu season will be relatively predictable.
2009 was the only year in which more than 20 children died from the flu.

they float because they are less dense than the water itself

something denser than water, like a rock, will sink to the bottom

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.
