. SCIENTIFIC INQUIRY Bats emit ultrasonic sounds and then use the returning echoes of those sounds to locate and capture flying insects, such as moths, in the dark. In response to bat attacks, some tiger moths make ultrasonic clicks of their own. Researchers hypothesize that tiger moth clicks likely either (1) jam the bats sonar or (2) warn the bat about the moths toxic chemical defenses. The graph below shows two patterns observed in studies of moth capture rates over time. 100 75 50 25 0 1234567 Time (nights) Moth capture rate (%) Tiger moth species A Tiger moth species B Bats in these experiments were naive, meaning that prior to the study the bats had not previously hunted tiger moths. Do the results support hypothesis (1), hypothesis (2), or both? Explain why the researchers used naive bats in this study
