Answer:
A) A population of squirrels is separated by the Grand Canyon. The two subpopulations evolve into two distinct species.
Explanation:
The answer is <span>0.132606 amu.</span>
The mass defect (Δm) is the total mass of protons and neutrons minus the mass of the atom.
<span>mass of an oxygen-16 atom: 15.994914 amu
mass of a proton: 1.00728 amu
mass of a neutron: 1.00866 amu
</span>
An oxygen atom has 8 protons and 8 neutrons. Therefore:
Δm = 8 · 1.00728 + 8 · 1.00866 - <span>15.994914 = 8.05824 + 8.06928 - 15.994914 = 0.132606 amu
</span>
