How different pollutants contaminate our water resources?

Make a claim to answer the question:  How different pollutants contaminate our water resources?
Information presented in the video and the rest of the chapter will provide EVIDENCE to support your claim or you may find evidence that make you change your claim. Which you can!!  As long as the evidence supports the new claim.
When all of the evidence has been collected, you will explain the reasoning for your claim using the evidence as support

Fukushima radiation

(a) Read the posted NYT article on "Fukushima: When Radiation isn't the Real Risk". (b) Do a brief calculation to show how they arrive at the quoted number of expected cancers due to radiation. (c) Write a brief summary of the key argument the article is making which should influence decision makers in emergency situations. (1 page max for (b)+(c) combined.

Organisational Context

Describe in your own words what is meant by the term organizational context. Then, perform research in  Google Scholar, or a professional or peer-reviewed source and select an example of an organization with which you are familiar, or an organization that you would like to know more about. You can use a business organization, a government division or agency, a non-governmental organization, or a non-profit business as your example.

NOTE: I highly recommend you use a small to medium sized entity that has already been certified to the 14001 standard in your analysis, or you could use the organization that employs you. You will have the option of performing more detailed analyses of this organization as the class progresses. Many states have environmental leadership programs which recognize companies with certified environmental management systems. For some examples, Colorado's Environmental Leadership Program can be found at https://www.colorado.gov/pacific/cdphe/environmenta

Chose from one of these two articles. OConnell, Mark. Why Would Anyone Want to Visit Chernobyl? New York Times Magazine, March 29, 2020. https://www.nytimes.com/interactive/2020/03/24/magazine/chernobyl-tourism.html.
Popkin, Gabriel. Can Genetic Engineering Bring Back the American Chestnut? The New York Times, April 30, 2020, sec. Magazine. https://www.nytimes.com/2020/04/30/magazine/american-chestnut.html.
Read the article and write an essay analyzing it from the point of view of what we have learned in this class. At the minimum, you should address the following questions: Do events described support the concept of Anthropocene? How are they related to the idea of wilderness? How do they relate to the ideas of "traditional" or "new" conservation? What issues of environmental justice are raised? Which arguments we encountered in readings for this class, are best supported by this article? (That is, think about all the readings we have done in this course, which one(s) would be

Complete all required readings and viewings in this week's Study Plan before beginning this assignment.
Initial Post

We have examined a lot of the current and future applications of AI. There are several areas that are particularly prone to concerns about the ethical implications for AI, these include warfare, robotics, criminal justice, health care, and the workforce. These are areas where AI is going to be causing major disruptions to our lives. For this discussion, you will be choosing one of these topic areas to explore for both the positive and negative potentials. 

First: Select one of these topics:

    Warfare
    Robotics
    Criminal justice
    Health care
    Workforce 

Next: Go to the EC Library Resource Guide for NS110 and this module. https:/

Antibodies have been used in drug development in targeting specific tissues and part of the normal humoral immune response. Recently, new anti-cancer antibodies have been developed as a new type of chemotherapy agent.

-Identify a disease and describe how you could design a drug based on an antibody.
-Describe how this drug could enhance the immune response.
-Explain why this could be an effective treatment for that disease.
-Identify both, advantages and disadvantages, to this strategy.


Please be sure to validate your opinions and ideas with citations and references in APA format.

Your goal is to present how you are going to synthesize 15 mmol that ester using Fischer esterification method. Narration audio of PPT no more than 15 min in length.

Slide 1-Reaction mechanism   
  Write out the full mechanism (with arrows) for the formation of the ester that was assigned (must be handwritten).

      Comment on the quantities of alcohol/acid/catalyst used in the experiment in terms of reaction kinetics and/or thermodynamic reasoning. Discuss the yield of the reaction in the above terms.

(ask yourself: how would the equilibrium of the esterification reaction change with the addition or removal of H2O/catalyst?)


Slide 2-5-Yield calculations & Procedure- step by step detailed procedure
-Show your handwritten yield calculations (picture from lab notebook is fine)
-Detailed, step-by-step procedures must include

Setting up reaction:

      Follow table from page 105 format
