Albinism
ALBINISM Albinism. The word albinism refers to a group of inherited conditions. People with albinism have little or no pigment in their eyes, skin, or hair. Recently a test has been developed to identify carriers of the gene for ty-neg albinism and for other types in which the tyrosianase enzyme does not function. The test uses a sample of blood to identify the gene for the tryrosinase enzymes by its code in DNA. The above test does not apply to to one type of albinism, called X-linked ocular albinism. For X-linked inheritance, the gene for albinism is located on an X chromosome. Females have two X chromosomes, while males only have one X and one Y chromosome. This X-linked albinism accurs exclusively in males. The gene is passed from mothers who carry it to their sons. The mothers have subtle eye changes which an ophthalmogist could identigy, but mothers usually have normal vision. For each son born to a mother who carries the gene, there is one in two chance of having X-linked ocular albinism. The description is a hereditary deficiency pigmentation. This could involve the entire body or part of the body. This is believed to be caused by an enzyme deficiency involving the metabolism of melanin during prenatal development. This can be inherited by an dominant or recessive trait. In complete albinism, there is lack of pigmentation in skin and hair, as well as in retinal and iris tissue; in incomplete albinism, skin and hair may vary from pale to normal; in ocular albinism, function may vary from norma to impaired. Impairments may involve the retina and iris. If a person has albinism then they usually have somewhere between 20/70 and 20/200 visual. Ty-Neg albinism or also called type 1A results from a genetic defect in an enzyme called tyrosinase. Tyrosinase helps the body to change the amino acid tyrosine into pigment. An amino acid is a building block of protien. Albinism is passed from parent to their kid through genes. For nearly all types of albinism both parent must carry an albinism gene to have a child with albinism. Parents may have normal pigmentation but still carry the gene. When both parents carry the gene, there is a one in four chance at each pregnancy that the baby will be born with albinism. This type of inheritance is called autosomal recessive inheritance.
Xeroderma Pigmentosum is a genetic disorder caused by a mutation in one of any seven genes. This genetic mutation is an autosomal recessive trait. This disease was discovered in 1874 by Hebra and Kaposi. People with this disease cannot have direct exposure to sunlight, or blisters on the skin may occur. There are only about 250 people in the world with this disease.
E. D. Hirsch and Lisa Delpit are both theorist on teaching diverse students. Both of these theorist believe that when teaching diverse students, teachers need to see their students for who they are. Seeing your students for who they are, means you look past the color of your students’ skin and recognize their culture. According to Stubbs, when teachers look at their students equally, no matter the color of their skin, then the teacher is considered colorblind (2002). Being colorblind is not a great thing because we should not treat all of our students the same, since each student is different. It is important to see our students for who they are because our classes are unique. Instead, our classes represent a rainbow underclass. According to Li, the rainbow underclass is the representation of families who are culturally diverse and economically disadvantaged (2008). In order to meet these student’s needs, teachers need to think about the struggles that each student face.
Benjamin Franklin is best known as one of the four founding fathers of the United States. He was one of the most extraordinary human beings our world has ever known. Benjamin Franklin was a writer, inventor, scientist, businessman, a diplomat. He was a mastermind. He helped shape America's society and character, to what is known as today. While reading and learning about Ben Franklin, you will witness the beginning of the United States. You will see how this man, changed America. Now, through my own words, meet Benjamin Franklin.
Benjamin Franklin is considered to be one of the most well-known Founding Fathers, as he helped in writing the Declaration of Independence and the very first Constitution of the United States. Who was he other than a man who fought for colonist’s rights however? Franklin was a brilliant inventor who created many innovating and life changing mechanisms, such as the world’s very first almanac, bifocals, and the lightning rod. He was also a major figure in the American Enlightenment, which restored art, science and music, spreading moral philosophy all across the colonies. Although he was never elected to the role of President of the United States, Franklin served in several other parts, such as the first postmaster general for the colonies in
During the 1920’s women were fervently depicted as inferior to men and incapable of the success. In the novel The Great Gatsby female characters are subject to gender based stereotypes and blindly follow culturally accepted norms which dictate their place and position within society. The expectations placed upon the female characters to comply with the norms of society limit their potential to become successful in comparison to the male characters, who are successful in the 1920’s. Within The Great Gatsby, Fitzgerald illustrates the female characters as socially and economically limited and dependant, due to the strong implementation of patriarchal roles of men in society. Women are confined
Benjamin Franklin, a man who is considered one of the first “Americans” (many consider him as the first) where he had a great role in the establishment of the independence of the United States of America. He had a great deal of major and minor professions, which were of vital significance during that period of time. These professions include being a politician where his theories were remarkable, a scientist where he himself was an inventor, a postman, a diplomat and last but not least a man responsible for a lot of discoveries in the field of physics.
Albinism is a genetic condition present at birth, characterized by a small amount of melanin pigment in the skin, hair and eye. Albinism is an occasional inborn sickness related with vision difficult, which affect one in seventeen thousand persons. It is not a contagious disease and cannot be spread over contact. Albinism affects individuals from all races. Most folks with albinism have parents with a normal color of skin. Some may not even recognize that they are Albino until later on in their life. This paper will be based on the study of albinism, causes, types, the genetic transmission and some possible medical problem.
All organ system work together; in order to keep and support the conditions that the cells, tissues, and organs need to function properly. Each organ system has an important function in the body. There is one system that is not as well known as other; it is the integumentary system. Most people know the organs of the integumentary system, but they do not know that these organs work together to form this system.
As Mark Twain once declared, “What would men be without women…” This quote is clearly illustrated in F. Scott Fitzgerald’s timeless masterpiece The Great Gatsby. The Great Gatsby is the tragic love story of a poor man who falls in love with a rich girl and spends the rest of his life getting rich to impress her; however, in the end he dies alone without his love fulfilled. Although Fitzgerald’s novel is mainly androcentric, he uses several females each unique in their personalities to highlight the male characters, and to show that although people may have different desires, motivations, and needs they are not that different from each other.
Throughout Fitzgerald’s “The Great Gatsby,” the role of women can be examined to demonstrate anti-feminism. Initially, Daisy is viewed as an innocent, loving character, but once her true motives are revealed, it is clear that she is very corrupt, desiring only money and power. This is used to show the stereotypical female who lives under the man for his possessions, and lacks the self-respect to stand against the opposite gender. She is not the only female to act like this, there are many, but her case is the most important because it directly influences all of the main characters. Gatsby is also portrayed as a stereotype: the boy who wants his true love and will do anything and everything to get her, even be accused of murder. Once each character
Who was Benjamin Franklin and what accomplishments did he make that affects us today? Benjamin Franklin was born in Boston, Massachusetts, January 17, 1790. Benjamin Franklin “was the tenth son of soap maker, Josiah Franklin. Benjamin’s mother was Abiah Folger, the second wife of Josiah” (Electric). He became a diplomat, scientist, author and also a philosopher. Benjamin Franklin developed into a great man and became known as one of the founders of the fathers of the Declaration of the Independence; thus known as one of the many accomplishments he made throughout his lifetime. Research, documentaries and an autobiography written by Benjamin Franklin himself detail all his accomplishments. An amazing man, Ben Franklin became to be so far ahead of his time to create the many inventions he developed within his life time. Many historians characterize him as a genius as well as a national icon. One of Benjamin Franklin’s successfully revolutionized the newspaper business and printing trade.
F Scott Fitgerald’s novel, The Great Gatsby, is centred upon 1920’s America. In the text, characters such as Myrtle Wilson, Jordan Baker and Daisy Buchanan are all carefully constructed to reveal various attitudes held by America in the early 20th century. Overall, the construction of female characters in The Great Gatsby showcases an accurate representation of women in the time period the text was composed in.
According to Darwin and his theory on evolution, organisms are presented with nature’s challenge of environmental change. Those that possess the characteristics of adapting to such challenges are successful in leaving their genes behind and ensuring that their lineage will continue. It is natural selection, where nature can perform tiny to mass sporadic experiments on its organisms, and the results can be interesting from extinction to significant changes within a species.
The gender issues in F. Scott Fitzgerald’s The Great Gatsby adhere to the traditional gender roles of a male-dominant society where women are sexually objectified and made inferior, while men are portrayed as the dominant gender. The narrator’s relationship with the female characters of the novel and their character traits reveal not only the established patriarchal society in the novel, but the chauvinistic attitude of the author as well. While feminine conformity to the ideal standards of women in a male-dominant society is reflected through characters such as Daisy Buchanan and Myrtle Wilson, male characters such as Tom Buchanan and George Wilson appear to represent the traditional man, thus satisfying the ideal gender roles of a male-dominant society. Though it appears that Nick Carraway’s admiration for masculinity allows him to suffer from his potential anxieties about his own masculinity, Carraway’s male chauvinistic mentality is certain because of his enforcement of traditional gender roles that exerts dominance over women in the novel. Carraway’s attraction to Jordan Baker’s masculine traits and his fascination of the socioeconomic status of men, such as of Jay Gatsby’s and of Tom Buchanan’s, display his conformity to the ideal, traditional standards of gender roles in a male-dominant society that explain his admiration for masculinity.
Albinism is a very serious disease that could end up in death. Albinism is a recessive inherited defect in melanin, which is metabolism in which pigment is absent from skin, hair, and eyes. Albinism in hair, skin, and eyes is called oculocutaneous albinism. Humans that have oculocotaneous albinism are not able to produce melanin. These people have white, yellow, or yellow brown hair, very light ( usually blue ) eyes, and very pale skin. Their eyes may appear pink because they have very little pigment.
