With which method can one typically observe tissues?

Tissues are groups of cells that are similar in structure and function. Tissues make up organs.  There are four main groups of tissues. The four groups of tissues include connective tissue, epithelial tissue, nervous tissue, and muscular tissue. Below, three methods of observing tissues have been identified.

• 
  Transmission electron microscopes (TEM) is one way that tissues can be observed. A TEM shoots electrons in a beam that is focused on an object. An image-producing system then focuses the electrons that passed through a specimen to form a highly magnified image of the specimen. The TEM’s image-recording system converts the image produced by the electrons into an image that can be interpreted by the human eye.
  


• Fluorescent stains can be applied to tissues so they can be observed under fluorescent microscopes.


• 
  Confocal laser scanning fluorescence microscopy is beneficial in observing thicker samples of living tissues.
  

I need a summary of Unwind by Neal Shusterman.

Unwind by Neal Shusterman creates a dystopian future in which abortion has become illegal, but as a result of the controversies concerning abortion in the United States a bizarrely improbable set of laws have been passed in which parents can choose to have their children "unwound" or transformed into unwilling organ donors between the ages of 13 and 18. Much of the novel works out the premises of this sort of society, including people anonymously leaving unwanted babies on the doorsteps of others. The complexity of the moral issues concerning right to life and the nature of life is expressed in the following quotation from the novel:

In a perfect world everything would be either black or white, right or wrong, and everyone would know the difference. But this isn't a perfect world. The problem is people who think it is

Naturally, many of the teenagers who are selected to be "unwound" don't want to die or donate organs. Thus we have three teens who rebel who are the main characters of the novel, the protagonists Risa and Connor and the selfish and manipulative Roland, who are all scheduled to be unwound and flee to avoid that fate. They escape to the Graveyard, a sanctuary for teens run by Admiral Dunfee, where a power struggle ensues between those loyal to the Admiral and Roland and his followers. All three teens end up being captured and sent to Happy Jack Harvest Camp to be unwound. Roland dies, but Connor and Risa survive to take over the Graveyard. Their friend Lev, who who is a devout and morally conflicted teen, campaigns to change the laws about unwinding and succeeds in reducing the maximum age at which a teen can be unwound. 

Explain the conflict man vs. nature in Shakespeare's Romeo and Juliet.

While the main conflicts in Shakespeare's Romeo and Juliet involve man vs. man, man vs. society and man vs. fate, there are two instances of man vs. nature. A conflict involving man vs. nature occurs when the characters battle against something in nature that is not caused by human beings.

In Act III, Scene 5, Juliet struggles against nature when she thinks she hears the nightingale, a symbol for the night, singing outside her window. She very much wants the night to last because she is with Romeo on the eve of his banishment from Verona. After killing Tybalt, Romeo must leave or risk apprehension by the Prince and possible death. When Romeo gets up to leave, Juliet implores him to stay:

Wilt thou be gone? It is not yet near day.
It was the nightingale, and not the lark,
That pierced the fearful hollow of thine ear.
Nightly she sings on yond pomegranate tree.
Believe me, love, it was the nightingale.

Fate has conspired against Romeo and Juliet and now nature hinders the couple from being together. Finally realizing it is actually a lark, "the herald of the morn," Juliet urges Romeo to leave.

The second example of man vs. nature is in Act V, Scene 2 when Friar John, who is carrying Friar Lawrence's message to Romeo, is detained by a plague threat. Friar John never delivers the all important note which explains the Friar's plan for Juliet to fake her death. The plague ravaged Europe for many years and was a problem in Renaissance Italy. John explains the situation to Lawrence:

Going to find a barefoot brother out,
One of our order, to associate me,
Here in this city visiting the sick,
And finding him, the searchers of the town,
Suspecting that we both were in a house
Where the infectious pestilence did reign,
Sealed up the doors and would not let us forth,
So that my speed to Mantua there was stayed.

The letter would have explained to Romeo that Juliet was still alive and he should arrive at Capulet's tomb at the time of her awakening to take the girl away, presumably to live happily ever after. But, as with the deadly feud between the two families, and a malevolent fate, nature goes against the two young lovers.  

Can you compare and contrast madness and social hierarchies in Diary of a Madman and The Bell Jar?

In Gogol's "Diary of a Madman," the madman is obsessed with his boss and his boss's daughter. He is also obsessed with rank. This emphasis on rank is a common theme in Nineteenth Century Russian literature as the social hierarchy at the time involved a class system, referred to as the Table of Ranks. As a civil servant, the madman ranks relatively low on this scale. It could be argued that the infatuation with rank is what leads to his madness. By the end of the story the madman believes himself to be the King of Spain (which of course would make him very high ranking).

In Plath's The Bell Jar, the social hierarchy relates not to class, but to gender. Esther's madness seem to stem from anxiety over her lack of freedom and opportunity for self-fulfillment in a patriarchal society.

In the novel The Great Gatsby, what are the advantages and effects of using Nick as a first-person narrator?

There are many advantages of using Nick Carraway as the narrator in the novel The Great Gatsby. At the very beginning, we learn that Nick had been taught by his father to reserve his judgement of others, especially those who weren't as privileged as he was:

“Whenever you feel like criticizing any one,” he told me, “just remember that all the people in this world haven’t had the advantages that you’ve had.” (Chapter 1)

Nick is the quintessential observer, the outsider who sees all that goes on around him and yet manages to remain objective, at least until he meets Jay Gatsby, for whom he develops an affection and a friendship. Nick is also true to himself and is not swayed by the wealthy crowd nor tempted to do things that would go against his proper Midwestern upbringing.

“Reserving judgments is a matter of infinite hope.” (Chapter 1)

"I am one of the few honest people I have ever known." (Chapter 3)

Nick is also much more reliable than the other characters in the novel. He is more grounded and represents a hard-working individual. While Gatsby and the Buchanans are self-indulgent and lead ostentatious life styles, Nick is a man of more modest means with a practical nature. The effect of having Nick be the narrator is that we, the readers, can identify with someone like him, the more "normal" character in the novel. For these reasons, Nick is a natural choice for narrator. 

Who made the Chinese Exclusion Act?

Congress passed the Chinese Exclusion Act in 1882. This law prevented immigration to the United States from China for ten years. It also prevented people from China that were already living here from becoming citizens during this ten- year period. This law was extended in 1892 and made permanent in 1902. It was repealed in 1943.

There was a growing fear that immigrants from China were taking jobs from Americans, especially those who were working on the railroad. There also was a concern that the growing influx of Chinese workers was driving down wages that were paid to the workers. As a result, the Chinese Exclusion Act was introduced in the House of Representatives, passed by the Senate, and signed into law by President Arthur. This was the first law passed that limited immigration of a major group of people from a specific part of the world.

What does Martin Luther King, Jr., think the role of the church should be in addressing racial problems, and what theological arguments does he...

Though Martin Luther King, Jr. was a preacher, he was more of an activist for civil rights.  If you'll think about it, how many times have we heard him make reference to anything scriptural? There was moreso, peaceful marches and sit-ins at dining counters, etc.  Even within the pulpit, his speeches were more political than religious.  I believe he was a Christian but his focus was more on fighting for the rights of the underprivileged than the saving of the souls of men.  He made reference to the Constitution that "All men are created equal," but no reference to Word of God.  However, I do believe that his stance of the role of the church in addressing racial problems was that the church, being the people of God, should represent the love of God in all circumstances.  The bible says that God so "loved" the WORLD...not just whites or blacks. He loves us all.  Jesus came to seek and save the lost...not just whites or blacks.  I believe Dr. King would want that love represented in order for those who were contrary to be drawn in by that love.  The bible says that "by this love shall all men know that you are my disciples."  God says, "with lovingkindness have I drawn you." I believe that would be the message of Dr. King.
