Respond to the following questions:

1. When you purchase a bottle of water, is the water totally pure? If not, what is in the bottle other than the water?

2, Arsenic is a naturally occurring element. It is found in soil and rock deposits around the world. It is also known for its toxic effects on the human body if sufficient quantities are consumed. If arsenic is found in bottled water, is this an automatic cause for concern? Do a web search to determine the EPA acceptable limit for arsenic in water.

Hello,
I want you to do a research on COVID-19 Infectious Disease Research Project,
the 2 categories I chose to work on for the research paper are topic number 4 and 6
4) pathology
6) social-political-economic effects

There is a file to the instructions in the additional materials
Thank you for your help

After the studying the photo of Nowitna River in Alaska (above), answer the following questions:

1) What has happened to the river to produce the topography here?

2) How might the course of the river change over time?  Be specific!

3) Does the river appear to be eroding more prominently on the outside bank of a turn or on the inside bank?  How do you know?

4) Is there evidence of depositional work here?  How do you know?

5) What other fluvial landforms are evident in this photo?  How can you tell?



Each question must be included with its corresponding answer. 

Write an Abstract to summarize the article "(R5_Langkawi_TourismDevelop.pdf)" using this format:-
i) TITLE (inc. Author, Date etc.)
ii) ABSTRACT (inc. Key concepts & Findings - be sure to paraphrase, not just copy & paste!);
iii) KEYWORDS (choose 3-5)
iii) QUERY (at least one question/critical comment)

***PLEASE CHECK AT WORK FORMAT I GAVE YOU, AND USE THAT FORMAT TO DO THIS ESSAY.
Remember the goal is to make a Summary.

Five articles reviewed included in the attachments and highlighted with its main points.  Format/structure of the paper included as the draft document.
Intructions and format is provided in the draft document. Just have to fill everything. Body needs to be about 5 pages. Discussion is about 1.5 pages.

Using data from the Australian Bureau of Meteorology website, find the current monthly values for the following: The Southern Oscillation Index (SOI) and Nio 3.4 index. What phases do these values indicate the El Nio-Southern Oscillation (ENSO) is in? La Nia or El Nio or neutral conditions? All required information for this exercise is found at http://www.bom.gov.au/climate/enso/. Present your findings as a brief 200-250 word brief essay describing the relationship between SOI, Nio 3.4 and ENSO. Brief essays should have an introductory and concluding statement. Please use where appropriate in text citations and references and use the Harvard Reference Guide

In this module, the importance of ice cores and an application of the oxygen isotopic ratio is discussed. Request: Present a brief essay answer (about 250-300 words) describing how the isotopic ratio is likely to change in the Polar Ice caps, precipitation, and the global ocean during the onset of the next glacial period and a subsequent return to an interglacial period. Brief essays should have an introductory and concluding statement. Please use where appropriate in text citations and references and use the Harvard Reference Guide.

How were the pyramids built? Although it is clear that the Egyptian pyramids
were manmade, not everyone agrees (anyone seen Ancient Aliens?). How would you
convince a skeptic otherwise, with an evidence-based approach? Don't focus only on how
the stone blocks were lifted into place build a broader argument based on how the
Egyptians utilised natural resources, manpower and engineering knowledge. Include one or
two sentences stating why you think it is important to counteract pseudoscience.

I also already wrote an annotated bibliography on this topic. I have 4 sources there and I will need 6 more.

Population growth and distribution have significant roles to play in the sustainability of the world's vast resources. Several studies have indicated that uncontrolled growth of deer populations lead to negative ecological consequences, including decreased biodiversity. The result of the deer overpopulation in many areas has led to radical alterations of shrub architecture, contributing to increased habitat loss for some important species.

Many people have varying opinions on the best way to approach the issue. Watch the following video about the deer overpopulation in Wayne County, PA (from 2015). http://wnep.com/2015/01/06/controversial-plan-to-manage-deer-population/

Also, read the following article: Pursell, A., Weldy, T. & White, M. (2013). Too Many Deer: A Bigger Threat to Eastern Forests than Climate Change? Cool Green Science. Accessed at http://blog.nature.org/science/2013/08/22/too-many-deer/ on August 16, 2016.

Why are so many deer populating the eas

Assignment Overview
In this module, you have learned about how carrying capacity imposes restrictions on population growth, and how human economic growth and land use can threaten biodiversity. In this Case Assignment you will look at these topics from three perspectives:

Case studies of government regulation of land and trade restrictions to address threatened species in the Economist article: Political Responses: Where eagles dare
Examples of large mammals and the size of the habitat necessary to support them
The cost of conservation in a Botanical Garden case study

Case Assignment

Part I

To prepare for this Case Assignment, answer the following in paragraph format (one paragraph should be plenty):

Define invasive species using the U.S. Department of Agriculture (USDA) website: National Invasive Species Information Center. USDA. invasivespeciesinfo.gov
Provide three examples of invasive species in your region.
