How did the color of the trees in the squirrels’ environment change? Explain what happened to the squirrels over many generations.

The squirrels over many generations will change shades and colors to match more similarity to the new color of the trees. The colors of the trees could have changed from the weather or maybe there is a hybrid of the trees.

Explanation:

I am guessing but I hope this helps.

there really is life in the deepest part

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.
