The habitat of a moth species included trees with both light and dark colored bark.Therefore the moth species included both light and dark colored variants.Then the light-colored trees were wiped out by a disease, and within a few years nearly all the moths in this forest were dark colored. Which of the following choices BEST explains what happened?

• The light moths that survived all had dark offspring in order to adapt to the change.
• The dark moths were less visible to predators, so mostly light moths were eaten.
• The few light moths that survived did not mate, and therefore they had no offspring.
• The light moths changed their wing pigments to darker colors to avoid being eaten.

Catfish have dorsal fin spines, which help defend against predators, and caudal fins, which help to propel the fish through the water. A swim bladder controls how high or low the fish sits in the water and gills allow the fish to breathe by taking oxygen out of the water. Catfish spend most of their lives at the bottom of freshwater lakes and streams. Which catfish trait may change (over many generations) if the pond habitat in which it lives becomes significantly deeper?

• Dorsal Fin

• Caudal Fin

• Swim bladder

• Gills
