20. $400 Question Topic 1 Alaska has rivers that are the homes to many salmon. These salmon travel upstream each spring to spawn. Government officials are planning to construct several large dams on these rivers. Although the dams will create some noise, they will produce much needed electricity for homes and businesses. Think of how the dams will affect the salmon’s ability to live in the river. Describe two effects that the proposed dams would have on the salmon’s ability to live in the river. Explain your answer. (2 Points)

21. $400 Answer Topic 1 Answer: Answers may vary. Since the salmon depend on traveling upstream to reproduce, the dam will interfere with the species’ ability to survive. Other possible answers could include that the dam will affect the level of food or water needed for the salmon to live. Rubric: Two Points – Response describes at least two effects that the proposed dams would have on the salmon’s ability to live in the river. One Point – Response describes at least one effect that the proposed dams would have on the salmon’s ability to live in the river. Zero Points – Response indicates no understanding of the concept(s).
