a population of snakes includes solid-colored snakes and banded (striped) snakes. on the mainland, the snakes are mostly solid. on a nearby island, the snakes are mostly banded. you hypothesize that the reason for this observation is that the environments on the mainland and island are different, and banded snakes are favored in the island environment. which of the answer choices are possible alternative hypotheses to explain why the snakes on the island are mostly banded? select all that apply. all of the answer options are correct. the environments on the mainland and island are different, and banded snakes are favored on the mainland. there is a predator on the island that preferentially preys on solid snakes. the island was colonized by just a few snakes from the mainland, and those snakes were banded.
