Select a scenario from the list below: There is a species of fish (with low numbers) that is having trouble traveling up and down the river because of a dam. Chose an area that is economically depressed but has a lot of species diversity, you need to protect the species while providing jobs for locals. An animal is being poached for its horn which is believed in some cultures to cure many diseases, it is not critically endangered. The demand for farming is increasing, which is destroying native forests and affecting their biodiversity. An animal is starting to become isolated because it is afraid to cross roads created by deforestation. Local birds typically migrate over the winter, but people are feeding them and thermal pollution at a local stream is keeping the water warmer the birds are not migrating, resulting in water pollution. A drought has been going on for a period of time; the water needed for homes, businesses, and farms has decreased lake and river levels impacting the amount available for local flora and fauna. Species are being found dead on local beaches due to plastic. Use the textbook and of info-graphic under course materials to find the best resource management practice to implement. Create a pamphlet addressing the following: What is the issue and why it would work Describe the restoration method you selected and why it would be best (with at least 2 examples of how it has worked in similar situations from peer reviewed sources) Time frame to complete the plan (include short and long term objectives) What is the end goal of the restoration project This assignment uses a rubric. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion.

Write a discussion about whether or not a science such as astronomy can be pursued in a "holistic" manner. My online dictionary defines "holistic" as follows: characterized by the belief that the parts of something are intimately interconnected and explicable only by reference to the whole. (More specifically, in medicine, it is defined as follows: characterized by the treatment of the whole person, taking into account mental and social factors, rather than just the symptoms of the disease.)You have almost certainly already encountered the word "holistic" in a familiar context such as medicine. The implications of the word will depend to some extent on one's perspective, but in general it would seem very likely to most listeners that a holistic viewpoint would indeed have value. Most of us would accept that the well-being of a patient might directly benefit from a doctor's attention to the individual's personality, psychology and state of mind, even if the specific treatment is focused on some ailment with a standard well-defined clinical course of treatment that has been proven through past application. In this discussion, considered thoughts about whether holistic approaches may be more insightful, valuable, and productive than those with a more focused technical and mathematical underpinning. We will ask you to frame these remarks in the specific context of astronomy (the subject of this course), but also invite you to speculate on how that may depend on the discipline in question. Consider and reflect upon the relevance of "holistic" approaches to astronomy, but also (if you wish) to other sciences of various kinds: from the life sciences such as biology and ecology, through the more technical engineering and physical disciplines, to very abstract pursuits such as the aforementioned pure mathematics. Do you believe, and can you provide a justification, to the contention that all science disciplines are open to broadly holistic approaches? Or are some of them, innately and uniquely, simply not amenable to such perspectives? Where does astronomy fit in this spectrum?

A phosphate-buffered saline solution is used in biological research because it maintains a particular pH, while also matching the number of ions in human blood. This solution is prepared by dissolving the following masses of these component into 1.00 L of deionized water:ComponentMass (g)NaCl8.00KCl0.200Na2HPO41.44KH2PO40.240The Ka for H2PO4¯ is 6.25 x 10-8. Answer the following questions about the phosphate-buffered saline solution. 1.(2 pt) Determine the total concentration, in moles per liter, for Na+ in the phosphate-buffered saline solution.2.(2 pt) Determine the total concentration, in moles per liter, for K+ in the phosphate-buffered saline solution.3.(2 pt) Determine the total concentration, in moles per liter, for Cl¯ in the phosphate-buffered saline solution.4.(2 pt) Determine the concentration, in moles per liter, for HPO42¯ in the phosphate-buffered saline solution.5.(2 pt) Determine the concentration, in moles per liter, for H2PO4¯ in the phosphate-buffered saline solution.6.(4 pt) Do the NaCl or KCl contribute to the pH of the solution? Explain your reasoning.7.(3 pt) What is the pH of the phosphate-buffered saline solution?8.(4 pt) What color would the solution be if red cabbage juice was added? Explain your reasoning.9.(4 pt) Write a reaction that shows how added strong acid (H+) will be absorbed by the phosphatebuffered saline solution, maintaining the pH.10.(4 pt) Write a reaction that shows how added strong base (OH¯) will be absorbed by the phosphate-buffered saline solution, maintaining the pH.11.(3 pt) You accidentally drop 0.0500 g of NaOH into your 1.00 L of prepared phosphate-buffered saline solution. What is the pH of the solution after this accident?12.(3 pt) You accidentally drop 5.00 g of NaOH into your 1.00 L of prepared phosphate-buffered saline solution. What is the pH of the solution after this accident?13.(3 pt) You are making your phosphate-buffered saline solution in a container that had a little solution in it. You assumed that the solution was pure water, but it turns out it was 5.00 mL of 1.00 M HNO3. What is the pH of the phosphate-buffered saline solution that you prepared? Hint: your final total volume is the sum of the 1.00 L phosphate-buffered saline solution and the 5.00 mL of the HNO3.14.(4 pt) You realize that you added 0.500 g of KCl to your solution instead of 0.200 g of KCl. Do you expect the pH to be impacted by the additional KCl in the solution?15.(4 pt) Will the pH of the solution change if the temperature of the solution is increased? Explain your reasoning.16.(4 pt) Why are both K+ and Na+ important for a biological buffer?
