In 2014, the city of Flint, Michigan, began using the Flint River for drinking water. The river water was highly corrosive because of the amount of salt and
chlorine that had been added to it. The water leached lead from pipes into the
drinking water. Based on the graph below, how would you expect the Flint
water supply to affect the local population?

Based on the observation that only male crickets produce a song, you hypothesize that a male's song is a form of communication to potential mates. you set up a simple experiment to test this hypothesis. in the laboratory, you place a male snowy tree cricket in enclosure a, which is adjacent to enclosureb. in enclosure b, you place other insects, one at a time, and observe their responses to the male's song. the enclosures are designed so that the two insects being tested cannot see or smell each other, but sound is transmitted from enclosure a to enclosureb.
