Hetch Hetchy Case StudyInstructions1. What were some of your first thoughts about the Hetch Hetchy Valley prior to the beginning of the dam construction? Would it be a place you would have liked to visit and spend time exploring or would you not be interested in something like that? Why or why not?2. The earthquake and following fires of San Francisco of 1906 were the events that justified the beginning of the Hetch Hetchy Project. The actual project didn't start until 1914 and water wasn't delivered to the Bay Area for the first time until 1934. Based on this timeline information from the case study, how justifiable was the project for the purpose of helping out San Francisco after the earthquake? Do you think other factors were involved in this process? Why and what could those have been? Describe at least 2 factors.3. The Hetch Hetchy environmental drama has been an issue now for a century. The same reasons it was originally debated are essentially the same reasons it is still debated today. Where do you stand on this environmental argument? Are you for the restoration of the Hetch Hetchy Valley by demolition to some extent of the O'Shaughnessy Dam or are you opposed to the restoration of the Hetch Hetchy Valley? Provide at least three reasons to demonstrate your support or opposition to the restoration of the valley.4. Regardless of if you are in favor of the restoration of the valley or not, if it were restored then it could become part of Yosemite National Park. A common complaint guests have after visiting Yosemite is that it is too crowded with other tourists. Some suggestions for controlling the number of visitors to Yosemite each year is to raise the price of entering the park so not everyone can afford admittance, have a lottery each year to determine who can enter the national park, or have park officials limit the number of guests entering the gate each day. Do these options seem reasonable to you? Why or why not? If Hetch Hetchy was restored and became part of Yosemite, many have wondered if more people would visit there and help reduce the flow of visitors to the more crowded parts of Yosemite. Currently, Hetch Hetchy is not an area that is visited by tourists on a regular basis like Yosemite. Do you think that might help with the congestion of visitors at Yosemite? Why or why not?

Bio Discussion (Please respond in time so that I can post and provide post for reply)Instructions:In this activity, you will use what you've learned about evolution to either find an example of it happening in recent history OR you can research a mutation, either beneficial or detrimental, and how it has contributed to the species evolution. You will need to use some online search skills to address either of these discussion topics.For your post, choose between one of the topics below: ($8.00)Topic 1Research examples of evolution that has been documented in current time.Choose one example for close analysis.Go to the Evolution in Recent History Discussion topic, and create a new thread of at least 250 words (excluding citations) containing the following information, using APA for citations and support:Describe the evolution that occurred in current time.Explain why the evolution occurred in current time.Topic 2Through research, find a single example of a beneficial or detrimental mutation.Go to the Mutations in Evolution discussion topic, and create a new thread of at least 250 words (excluding citations) containing the following information, using APA for citations and support:Identify and describe to your classmates the example of mutation that has been detrimental or beneficial. The species can be any species- humans or otherwise.For your replay, return to the discussion topic and reply to one of your classmates' posts who has not had a reply ($2.00).The reply should be evident you read the post and have a thoughtful response.The reply should be at least five sentences total. Replies should not say "cool post", "good idea", etc., but answer the post based on the following criteria.Is the post detailed enough to describe the discussion topic?Does the post grab your interest? Why/not?If applicable, is the post supported with proper scientific sources and citations?Comments will be taken into consideration for grading purposes.

Write a short paragraph describing each of the two rocks (thus two paragraphs). Photograph each rock with a sense of scale (a pen, a coin, a ruler). The photographs must be in focus. Use the "macro" setting on your camera; usually it's indicated by a little "tulip" icon like this: Post your pictures in the Rock Identification Working Area discussion board (one thread per assigned group of three students).With your assigned group (again; see Announcements), collectively identify your rocks and verify each other's identifications. You can seek validation of your identifications from the instructor.Once the identifications are solid, collaborate to answer the following five questions for each rock sample in the group:What type of rock is this? (igneous, metamorphic, or sedimentary)What are the dominant minerals in the rock? (e.g., quartz, biotite, calcite, etcWhat is the name of the rock? (e.g., basalt, granite, sandstone, etc.)Where is this rock from? (Where did you obtain the rock?)What processes were responsible for creating this rock? (Interpret the history behind this rock sample.)If igneous, describe the character of the melt that generated the rock (mafic or felsic) and its cooling history (aphanitic vs. phaneritic: extrusive or intrusive?).
