Environmental health essay

this assignment should include:
1. courses readings that I provided
2.A minimum of 5 other references, in addition to those used from your course
readings. Such sources should be drawn from reliable professional or academic sources engaged in the public debate. We caution you to be extra vigilant in determining the validity and authority of the authors and sources before inclusion in your own analysis. Examples of such sources include (but are not limited to): o Academic books and journal articles
o Government and industry websites;
o think tanks and environmental non government organizations, and o mainstream media

Further instruction is attached

*must cite course readings*

course readings :

Fauci, A.S. December 2005.  Emerging and reemerging infectious diseases.  The perpetual challenge.  Academic Medicine. 80(12): 1079-1085.

PART 2: ONE PAG

Global Climate Change

For the next discussion, research what are community groups doing to counteract this global climate change. Look for examples of Indigenous perspectives on the environment, sustainable lifestyle changes, earthen/green building, local community farming and markets, reforestation, planting trees, appropriate technology,  and permaculture to see what people are doing to reduce waste and emissions to sustain life on Earth.  Write 200 words about a practice that you find interesting or that you may even try to adapt at some point, summarize it, explain how it can potentially counteract global climate change. Relate specific examples of the book.

Post a link of where you got the information. A link to the website for non profit organization or the like acceptable.

Here are some links to get you started, but feel free to find others by googling any of the list of activities above.

writing a scientific article

Requirements
1. Examines, in detail, one or more sustainable solutions to an environmental issue.
2. Written as a scientific article, including an abstract, introduction, materials and methods,
results, discussion, conclusion, and literature cited. You are welcome to use tables and
figures, but be sure to reference them in the article, caption them, and place them after
the literature cited section. Use articles from the journal Ecology as a guide. *Note: you
do not need to format your writing into justified columns.
3. Cites at least 15 articles from peer-reviewed literature that have been published within
the last 10 years. The citations must support the point being made. If you make a claim,
you should cite it with at least one source! For some sections, nearly every sentence will
end up having a citation. I will check citations.
4. DO NOT EVER quote from a scientific article, even if you attribute it. You must write
everything in your own words.

The outline format:  Your outline must be formatted as described.  Please note that this format will be assessed in your grade:

Use an alphanumeric sequence
Sections should be indented and aligned
Follow the suggested order of the required elements
Use brief and bulleted but detailed and descriptive phrases.
The required elements: Your outline should contain the following elements in this order:

I.            The Introduction: This section previews your topic and the details you will cover in the body of your presentation. It should be very brief, but include:

    A.  The food, cuisine, invention or idea that you are going to discuss.

    B.  Why you chose this topic.

    C.  A preview of the regions where your topic has developed and then diffused to.

   

II.          The Body (Content Sections): I

Earth’s Atmosphere

Formulate an organized, clearly worded, and succinct initial post that substantively covers all discussion points stated for your chosen topic. Because your initial post will be scored on the degree to which you meet these standards, there is no set minimum word requirement. However, there is a set maximum word requirement confine your initial post to 500 words. Remember that we are all reading each others posts, and one that is succinctly written is more likely to be read and responded to, thus furthering our discussion on that topic.
Include at least one graphic, video, or image that visually adds to some aspect of your post - as they say, pictures are worth 1000 words!

Unit 7 & 8 Discussion

Unit 7 Discussion
Fungal Pathogens

Choose any one of the fungal pathogens and discuss its appearance, staining reaction, culture characteristics, disease caused, and epidemiological characteristics (where is it common, who is at risk).

Unit 8 Discussion
Disease Transmission

Explain how nosocomial infections are becoming serious health threats within healthcare system. Discuss the known methods used for breaking the chains of disease transmission.

Propose a way to educate the general public on their role in preventing disease transmission.

Each discussion must be at least 100 words

Outline-Comparing the four halogens – Chemical elements: properties and reactions

https://youtu.be/u2ogMUDBaf4


Watch the short video above concerning the halogen elements.  Submit 1) an outline of the video and 2) four reaction equations for reactions demonstrated in the video.  This assignment is worth 100 points.


How to write an outline


An outline presents a picture of the main ideas and the subsidiary ideas of a subject. Some typical uses of outlining might be an essay, a term paper, a book review, or a speech. For any of these, an outline will show a basic overview and important details. It's a good idea to make an outline for yourself even if it isn't required by your professor, as the process can help put your ideas in order.

Some professors will have specific requirements, like requiring the outline to be in sentence form or have a "Discussion" section. A students first responsibility, of course, is to follow the requirements of the particular assignment. What follows illustrates only the basics of outlining.<

Stellar Astronomy

Write a short five-page paper (12 pt Times New Roman font, double spaced, 1-inch
margins) on THE SOLAR SYSTEM that you have researched
using the internet. Include links, images, works cited of the information you consulted.
Minimum 3 pages text, maximum of 2 pages diagrams/references.

Please provide an overview and critical evaluation of the experimental evidence supporting a role for receptor-oligomers, both homoand heteromeric, in the regulation of signaling and intracellular trafficking of GPCRs.

THIS IS A UNDERGRAD LEVEL ESSAY!!! do not focus on what receptors are but on the specific GCPRS mediating the effects of neuropeoptides. and must provide experimental evidence from the papers listed below.

Large, highly complex networks of regulatory proteins control signaling, desensitization,
internalization and recycling of G protein-coupled receptors (GPCRs). These regulatory
interactions appear to be particularly important in mediating the effects of neuropeptides.
However, several lines of evidence indicate that interactions between the receptor proteins themselves may also play a major role in these processes.

Please provide an overview and critical evaluation of the experimental evidence supporting a role for receptor-oligomers, both homoand heteromeric, in the regulation of signaling and intracellular trafficking of GPCRs. Place a strong focus on GPCRs mediating the effects of neuropeoptides. Please use the review articles suggested below as starting p
