Rewrite this introduction part of an experiment

Nitrate is a polyatomic ion and is considered to be the only thermodynamically stable oxidation state of nitrogen in the presence of oxygen in seawater.2 It is considered to be a micronutrient controlling primary production in the euphotic surface layer in many sea areas. Nitrite is the intermediate compound in the microbial reduction of nitrate, or in the oxidation of nitrogen compounds, such as ammonia.2 The concentration of nitrite in nature is very low (< 0.1 µmol/dm3); however in the transition zone, the thin layers of high nitrite concentrations may occur (> 2 µmol/dm3) along with low concentrations of dissolved oxygen (< 0.15 cm3/dm3). Since the nitrogen in nitrite has an oxidation state of +3, it makes it thermodynamically unstable relative to the other nitrogen containing molecules in seawater, such as nitrogen gas, ammonia, ammonium, and nitrate.1Due to this instability, nitrite is considered to be an intermediate in the nitrogen cycle in seawater. Therefore, nitrite is easily oxidized to a more stable compound, such as is nitrate in a process called nitrification which involves two reactions:2

2NH3+ → (reaction 1)

+ → (reaction 2)

In reaction 1, ammonia is oxidized into nitrite by reacting with dissolved oxygen in seawater.Once the nitrite is formed, it is further reacted with more dissolved oxygen to form a stable oxidation state of nitrogen, which is nitrate as shown in reaction 2.1In this experiment, the Griess Reaction method is used for the determination of nitrite in seawater. This procedure is modified from the method developed by Bendschneider and Robinson. This reaction involves converting nitrite into a highly colored azo-dye compound. First, the nitrite in solution is allowed to react with sulfanilamide ion in an acidic solution leading to the formation of a diazo compound.The product is then allowed to react with N-(1-naphthyl) ethylenediamine (NED) to form a highly colored azo dye.

In the Griess Reaction, it is very important to add the reagents sequentially because the sulfanilamide and NED compete for nitrite.2 The sulfanilamide should be added to the sample first, and allowed to stand for 2 to 8 minutes, followed by adding the NED solution to reach the azo dye solution.2 The highly colored azo dye increases the sensitivity and selectivity into which its concentration can be determined by using the Spectrophotometer 20+. Spectrophotometric measurements of the absorbance are performed at 543 nm. Determination of the concentration of nitrite in seawater can then be calculated by incorporating Beer’s Law, seen in equation 1, by generating an external calibration plot of absorbance vs. concentration, where A is the absorbance, ε is the molar absorptivity in L/mol-1cm-1, b is the path length in cm, and c is the concentration of the analyte in mol/L-1. An external calibration curve was then generated, as the solutions were not known to have a matrix effect.1

A = εbc(equation 1)

Can you help with part 1 and 2

Part 1

A ministry leader’s reputation in ministry is often as important as the reality of who he or she is and what that person does. How can you be genuine in your interpersonal relationships that lead to effective communication and a positive reputation? What do people look for in ministry leaders that cause them to trust those in the ministry? What steps are you taking already to ensure your reputation is solid as you enter full-time ministry following your studies?

Part 2

One of the side effects of ineffective interpersonal communication is the cycle of vicious rumors that begin to circulate. Have you ever been the victim of rumors or know someone who has? Share one experience and provide suggestions on how to overcome the rumors about you once they begin to be shared publicly.

Those Winter Sundays


Sundays too my father got up early

and put his clothes on in the blueblack cold,

then with cracked hands that ached

from labor in the weekday weather made

banked fires blaze. No one ever thanked him.

I’d wake and hear the cold splintering, breaking.

When the rooms were warm, he’d call,

and slowly I would rise and dress,

fearing the chronic angers of that house,

Speaking indifferently to him,

who had driven out the cold

and polished my good shoes as well.

What did I know, what did I know

of love’s austere and lonely offices?

The Wind

by James Stephens

The wind stood up, and gave a shout;
He whistled on his fingers, and

Kicked the withered leaves about,
And thumped the branches with his hand,

And said he’d kill, and kill, and kill;
And so he will! And so he will!

Anthropology Question 400 Words

Question :

Argument/Persuasive Assignment


Write an essay that effectively argues your position on the prompt and presents evidence

from the texts as support. Evaluate and utilize outside sources, effective quoting and clear

analysis. Use and apply rhetorical strategies learned in your own argument.

Required Research/Readings:

This essay will require a minimum of

four (4)

outside sources, which you will need to

find. These source need to be reliable, credible and correctly cited in MLA. You need to

introduce these sources as you use them in the essay and correctly cite them in a Works

Cited page.

Length pages (not including Works Cited)


If you have ever had to convince your parents to let you borrow the car or

stay out late, or convince a friend or a partner that you should get pizza tonight and not

sushi, you have (possibly subconsciously) used argumentative/persuasion tactics to

convince the other person to agree with you. One of the greatest tools that we have as

writers is the power to persuade others, a skill that will be useful to you far beyond

English class.

The main purpose of an argument/persuasive essay is to convince your audience to

take your side on an issue by presenting a logical idea and supporting it with specific

and appropriate researched evidence.


For this assignment, you will develop an argumentative essay that establishes a clear

claim, supports it with researched sources and refutes at least one counter argument.

You will have two options:

A. Choose a controversial local (San Diego County) issue and argue in favor of one


Previous topics have included issues such as:

What should be done with Children’s Pool in La Jolla?

Should a new Chargers stadium be built? (over now)

How should the pollution in San Diego be controlled?

Should there be a casino in Jamul? (over now)

When choosing a topic for this option, a good idea would be to turn on

your local nightly news or open the newspaper to the local news section.

B. Choose a California based educational issue. These issues can deal with budgets,

student populations, classroom practices or anything else that impacts education

in statewide California classrooms.

With either option, you must argue for a specific course of action, meaning you

shouldn’t only say it is a problem. You should argue what we should do about it/what

changes should be made.

Your essay must also include a minimum of four (4) reliable scholarly sources used with

proper MLA citation and a Works Cited page.

Your essay should consider and refute at least one counter argument. You can address the

counter argument anywhere in the essay. Remember to present a possible counter and

respond to it with a logical refutation.

    • What is the central issue on race or racism reported in the news story?
    • What conclusions can you draw after reading the article?
    • Has society’s understanding, beliefs, and perspectives remained the same or changed? Provide an example.

9.Follow the requirements to write 300words answer

Respond to the prompt below in a single, cohesive essay of a
minimum of 300 words
. Use complete sentences and correct
grammar and spelling. Use APA formatting to cite resources appropriately.

Identify a present or past stressor that you have experienced. Describe
your physiological and emotional responses to the stressor. How did your
responses affect other aspects of your life? Discuss strategies you used or
could have used to cope with the stressors. How would you apply the strategies
that you have learned in this lesson in the future?


All the work has to be 100 percent original.

Any guides/existing papers you find on internet will definitely not be accepted

Any kind of plagiarism will definitely not be accepted.

Please read all requirement very very carefully and make sure it follows the instruction very well.


As most of you are aware, The President’sUniversal Health Care efforts resulted in what is commonly referred to as “OBAMA-Care” which is now in place and currently a very hot issue ……sparking unyielding controversy among the U.S. citizenry. This insurmountable attention and debate is centered around:

1. Individual Rights

2. True Capitalism /Free Enterprise? A new Capitalism? Is it Working?

3. The “Haves” and the “Have-not’s”

4. Too Much Government Regulation

5. Unfair Distribution of Wealth

6. Unethical practices

7. Corporations rule!

8. Shrinking Middle Class

9. Moral and Social Responsibility

10. Don’t forget to include the Donald Trump factor/impact.


All students must explain and elaborate on each major provision of “OBAMA-Care”. In addition, discuss the pro’s and con’s of this piece of historic legislation. Give a detailed explanations to support you position and be prepared to adequately defend your choice in response to your classmates’ opposition. I will be closely monitoring this forum to determine a grade scale for this assignment based your interactions. I expect debates, concessions, agreements, etc.

Many environmental organizational theorist have a central claim or conclusion to their arguments that organizations

Question 1:

Many environmental organizational theorist have a central claim or conclusion to their arguments that organizations, their success, their design, and their processes are mostly dictated by the environment. Write an essay explaining why environmental theorist believe this (that is explain the logic of their argument) and then write a critique of it in terms of whether or not you think they were correct? Are managers mostly constrained by the environment? Is the idea of managerial or organizational agency a myth? Be sure you use examples (made up or real) when both describing their theory and in your critique. You can also draw on any of the books we read to help you with your response. Good responses have details, examples, and draw from the material from the class including lectures, readings, postings, and movies.

Question 2:

Tett’s book on Silo’s identifies a major problem of many large organizations — the rise of isolated silos and a variety of problems that come from their isolation. She also suggests some cases where individuals and organizations have been able to “bust” these silos or think about them in different ways. Write an essay that uses organizational cultural and/or organizational environment approaches and make an argument that one of those two approaches does a better job finding solutions to the problems of silos as Tett sees them. To be specific, write an essay that first details the concept of Silos as offered by Tett, then briefly explains the problems they create, and then talks about some of Tett’s suggested solutions to the problem. Then make an argument that either the culture approach or the environment approach offers a meaningful way to see and deal with the problem of Silos.
