Orawing Conclusions About Brown Tree Ŝnakes The brown tree snake is native in areas such as Australia and eastern Indonesia. In those ecosystems, the brown tree snake is not causing the decline of bird or tree populations. So what makes this same species damaging in Guam? Identify some characteristics a species may possess that would fuel its ability to cause ecological damage, as the brown tree snake has in Guam. Provide some reasoning for why

A young researcher wants to test how well extremophiles, organisms that thrive in extreme conditions, live in different environments. She will do this by putting extremophiles of different species into different solvents. Because of limited lab space, she can run only one sample at a time, and each sample must remain undisturbed for 7 days. To reduce the total time needed to process all samples, the researcher decides to use two acidic solutions along with a control. The information below includes the extremophiles and the solvents the researcher will use in her tests. Species of Extremophiles T. prosperus A. aceti A. brierleyi H. acidophilum T. prosperus A. aceti A. brierleyi H. acidophilum Solvents Name pH hydrochloric acid 1.3 ascorbic acid 4.2 water 7.0 Name pH hydrochloric acid 1.3 ascorbic acid 4.2 water 7.0 Based on the tables, how many days will all of the researcher's experiments take? You may use the calculator. A. 7 B. 21 C. 49 D. 84
