Unit 3 Discussion
Bacterial Genetics

Discuss how bacterial and archaeal DNA is organized, as compared to eukaryotes. Explain the application of plasmids and restriction endonucleases in genetic engineering, with examples.

Unit 4 Discussion
Toxins

Differentiate between Endo- and Exotoxins. Using specific examples of bacteria, explain how the toxins they produce contribute to the virulence of those organisms.

Keep the discussions separate. They should have a reference page. The discussions should be at least 100 words each.

Write an essay discussing the similarities and differences between prokaryotic and eukaryotic cellular organisms.
Include the cellular characteristics, morphological, and, functional properties.
Identify prokaryotic and eukaryotic cells using specific examples (you must include 3 examples of each cell type.)
Show how the cellular characteristics allow for microbial survival within a therapeutic environment.

For this assignment, you will write a research essay, or create a presentation, about a scientist who contributed knowledge to the field of chemistry. Your essay, or presentation, should include the following information about your scientist:

Describe your scientist’s contributions and innovations to his or her field.
How did your scientist’s research and data influence future use of his or her findings?
Describe the background, interests, or goals that affected your scientist’s observations and conclusions.
Once you have selected a scientist, you will need to locate at least three different reliable resources to use to conduct your research. You may use textbooks, the Internet, or library books. These resources should be cited within your presentation and should be listed in a bibliography that you submit with your essay, or slide presentation. Use the Citations, Essay Writing, and Finding Reliable Resources tutorials to guide your writing.

If you have another method by which you would like to present your research findings, please have it approved by your instructor before you begin writing. No matter what presentation style you choose, be sure to use complete sentences and paragraphs, and include all of the necessary research required. You should also review the grading rubric before you begin. Select one of the following scientists, or pick another scientist of interest with your instructor’s permission, to conduct your research on: Mario Molina

You are to imagine that you are an atomic force microscope (AFM) instrument manufacturer interested in convincing a potential materials science customer that (1) they should be investing in an AFM to get crucial insights necessary for their research; and (2) they should buy your AFM. As part of your pitch, you should provide them with a brief introduction to what AFM actually isincluding a brief history of its development, what it allows you to do, and what typical operating parameters or performance metrics are. You are to do this as a 5-7 page (double-spaced) prospectus.

write about how some of the information can be used to  find water on other planets. What type of telescopes and what forms of light are being used? What are the key pieces of information they are looking form (the signature clues that water is present)?

break down the paper into these following parts:
-An explanation of the electromagnetic spectrum and the relationship between frequency/energy/wavelength
-The types of telescopes that can be used to detect water and what makes them so special
-The characteristic readings that scientists are looking for.

must be 5-7 pages, not including the citations page. Double spaced.
A citations page is required and must contain at least two references from scientific journals.

NO QUOTATIONS OF ANY KIND ARE ALLOWED, EVEN IF THEY ARE CITED

YOU MUST HAVE CITATIONS WITHIN THE BODY OF THE TEXT (if you use a piece of information, you must say which of the references you obtained it from)

Calculating Ksp From Molar Solubility – Solubility Equilibrium Problems – Chemistry
Duration: 16:02
User: n/a – Added: 11/30/17
Watch the video concerning this week’s topics of solubility equilibria and determining Ksp. Make an outline of the video (50 points) and give two examples of worked problems similar to the ones worked in the video (50 points) and submit it here. 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.

Basic outline form
The main ideas take Roman numerals (I, II, …) and should be in all-caps. Sub-points under each main idea take capital letters (A, B, …) and are indented. Sub-points under the capital letters, if any, take Arabic numerals (1, 2, …) and are further indented. Sub-points under the numerals, if any, take lowercase letters (a, b, …) and are even further indented.

MAIN IDEA
Subsidiary idea or supporting idea to I
Subsidiary idea or supporting idea to I
Subsidiary idea to B
Subsidiary idea to B
Subsidiary idea to 2
Subsidiary idea to 2
MAIN IDEA
Subsidiary or supporting idea to II
Subsidiary idea to II
Subsidiary idea to II
MAIN IDEA

It is up to the writer to decide on how many main ideas and supporting ideas adequately describe the subject. However, traditional form dictates that if there is a I in the outline, there has to be a II; if there is an A, there has to be a B; and so forth.

Outline example
Suppose you are outlining a speech about gerrymandering, and these are some of the ideas you feel should be included: voter discrimination, “majority-minority” districts, the history of the term, and several Supreme Court cases.

To put these ideas into outline form, decide first on the main encompassing ideas. These might be: I. History of the term, II. Redistricting process, III. Racial aspects, IV. Current events.

Next, decide where the rest of the important ideas fit in. Are they part of the redistricting process, or do they belong under racial aspects? The complete outline might look like this:

Gerrymandering in the U.S.

HISTORY OF THE TERM
REDISTRICTING PROCESS
Responsibility of state legislatures
Census data
Preclearance
Partisan approaches
RACIAL ASPECTS
Gomillion v. Lightfoot (1960)
Civil rights
Voter discrimination
Voting Rights Act (1965)
Majority-minority districts
CURRENT EVENTS
Effects of gerrymandering in 2012 and 2016 elections
Gill v. Whitford Supreme Court Case

It is only possible to make an outline if you have familiarity with the subject. As you do research, you may find it necessary to add, subtract or change the position of various ideas. If you change your outline, ensure that logical relationship among ideas is preserved.
