Astudent put together two different experimental set-ups as shown below. in figure 8-11, assume that the student placed plant a in direct sunlight for two days. how would the rate of photosynthesis of this plant compare with that of a plant grown under normal conditions?

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.
