what are the 4 postulates of natural selection? - 1. individuals vary in their traits 2. some of the variation is heritable 3. more offspring are produced than survive to reproduce 4. survival & reproduction are predictable; those with favorable traits reproduce most and pass their genes to the next generation what happens when a proton is absorbed by a molecule? - -it excites an electron into a higher energy state -the electron quickly drops to its ground state -releases the energy as l...
