PLEASE ANSWER ALL THE QUESTIONS PLEASEEEE

The presence of predators has been hypothesized to induce changes in prey behavior though chemical cues, even in the absence of direct interaction. Consider the graph below comparing activity levels of grey tree frog tadpoles, Hyla versicolor, reared either in the presence or absence of caged predators (dragonfly larvae, Anax longipes) in experimental ponds. Activity was quantified as the percentage of moving tadpoles observed over a 10-minute interval. Mean SE; n-30 tadpoles per experimental pond, F1, 10-6.12, P-0.033.
