Which of the following is the best explanation for why finches on one of the islands in the galapagos have large beaks while finches on another island have small beaks?
a.

b.
finches migrated until they found finches with similar beak sizes.
c.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

there are two significant figures.
