40 to test acidity levels of water, scientists test the ph. as acid rain falls, the ph levels in lakes and streams decrease. while certain animals can tolerate low ph levels, others are extremely sensitive to the effects of acid rain and cannot live under the conditions. students in maria's class know, based on the chart, the ph range tolerated by specific organisms living in the ponds surrounding their school maria and several other students are anxious to design an experiment to investigate this topic.

List two new traits (structural or behavioral) that each new species of rat might demonstrate as it adapts to the conditions on two of the four islands. choose only two islands that are described in the lesson. record the island latter and the major habitat feature of the island. then list two new traits each rat subspecies might demonstrate in order to survive the habitat on that island. note: new traits should be unique to that island and be in response to that island’s habitat feature. i cannot remember islands that were names in the lesson so only answer if you have done the lesson (5.13 life science 7b) choose 2 of the islands and describe a structural and a behavioral trait for a rat on each island so 4 total answers, 2 different structurals and 2 different behaviorals, one for each rat for each island
