African Allele Essay Example for Free

African Allele Essay It is a fact that Central Africa is a rural area while the United States is highly urbanized. This means that diseases are more prominent in the African territory, one of which is the malaria. This widespread illness caused evolution to favor a type of change in the human body to protect it from the deadly virus. This protection is the heterozygous make up of the hemoglobin gene, where one allele is the abnormal one that causes sickle-cell anemia. When comparing three types of persons, one with homozygous normal alleles, another with a heterozygous pair, and finally one with a homozygous pair of abnormal alleles, those with the heterozygous pair would have the greatest chance of surviving the conditions of Africa. Having a pair of normal alleles would not save a human from malaria infection, and having a pair of abnormal alleles would cause sickle-cell anemia that can also kill the patient. Thus, in places such as Africa, the population has quite a number of people having the heterozygous hemoglobin gene. The lower number of sickle-cell allele carriers in the United States can be attributed to two main reasons. First, malaria is not as prominent in the United States as it is in Africa. People then did not adapt that much and this abnormal allele haven’t evolved that much. Another is the intermarriage between Africans and Americans. If an African, who carries the sickle-cell allele, would marry an American having a homozygous healthy gene, their children would only have a 50% chance of getting that trait, as compared to an African-African marriage (both heterozygous sickle-cell alleles), where the chance of getting the allele is 75%.

John Steinbecks In Dubious Battle Essay -- Dubious Battle John Steinb

John Steinbeck's "In Dubious Battle" Summary This story opens with the main character named Jim Nolan leaving behind his former life and going to meet Harry Nilson, a leader of the "Party." Jim had a father killed in a riot, a mother who died, and a sister that was missing. He wants to join the "Party" because he wants to do something that will give his life meaning. He is accepted, and is introduced to other members of the party. The next day, Jim accompanies Mac McLeod to Torgas Valley to help workers organize a strike against the orchard owners in the valley. They meet a restaurant car owner named Al, who gives them food for free. Jim and Mac get off the train and meet a group of people. They help a woman named Lisa who is in labor deliver a baby. This event is important in the story, because this leads to the trust that Jim and Mac receive from all the other workers. They also meet London, the father-in-law of Lisa, who they will trust to lead the strike that they start. The workers already have a lo w mood, and when an old apple-picker falls out of a tree, the workers no longer wish to work in concern of their health. The workers start to strike, and assemble on the land of Al’s father, in exchange for picking his crop for free. London is charismatic, and takes the ideas from Mac to lead the strike. What will be the fate of the strikers, and what will Jim accomplish with his newly acquired skills? Sketch 1 Jim Nolan is a character who has always been angry at some type of institution throughout his life, which causes him to join the "Party." He is young, and goes from being an apprentice to a leader. He is keen and brave, which emanate from his innate leadership ability. Sketch 2 Mac McLeod is a seasoned veteran of the "red" work, as he knows more about fieldwork than anyone else does. He is an older character, who has broad shoulders, long arms, and dried and cracked lips. He uses his experience to lead and organize the men that he works with. Sketch 3 Joy is an enforcer who contributes to the "Party" by sacrificing his body in taking chronic beatings. He is a short man with a disfigured face. He is typified by some as not too bright and insane by others; he is very pugnacious, as he is willing to fight anyone. Sketch 4 London is a working stiff who is able to command... ... book included the strikers’ raid on the replacement workers, for it illustrated the roles of the different groups involved, such as the police, the vigilantes, the strikers and the scabs. Another intense portion of the book was that of the strikers’ raid on the apple orchard in which they attacked their replacements, for it showed the type of brutality that the strikers could carry out to send their message. The scene where Mac tortures a young boy who was caught around Anderson’s barn when it was set on fire is also a very intense scene. The aspect of the book that I did not care for was that of their being no explanation of what happened after the strike was resolved. It would have been interesting to learn about the type of effect that the strike had on the people, as well as what type of change occurred among them. Because of the interesting perspectives that this book provides, I would recommend that others read it. I would especially recommend this boo k to those who do not fully understand the power of the group and how it can be manipulated by its leaders, because the book goes into great detail of how this is accomplished. I would give this book a four star rating ****.

Lord of the Flies Lit Analysis Essay

Do novels have a deeper meaning to them than what the author writes? Golding reflects the two sides of human nature in â€Å"Lord of the Flies† by using imagery. Imagery is conveyed to develop the hidden meanings of human nature through the use of specific references through the themes of light and dark imagery. Golding conveys dark imagery throughout the novel by making references to evil. From the beginning of the novel the author introduces to the reader that something sinister is impending. He uses specific language to show the reader that the boys are like approaching animals, â€Å"Within the diamond haze of the beach something dark was fumbling along† (LOF 20). The choir in a way symbolizes a militaristic group being described as a â€Å"party of boys, marching approximately in step in two parallel lines and dressed in strangely eccentric clothing†(LOF 20). It is evident that the choir is evil because the book is written in the World War II period and it is likely that the choir symbolizes the Nazi Party which many people would be able relate them too animals or savages. Imagery is often developed when characters in the novel are savage like. Dark imagery reveals the character Jack to be evil when, â€Å"He passed like a shadow under the darkness of the tree and crouched, looking down at the trodden at his feet† (LOF 53). Jack is being compared to an animal trying to hunt down his prey while crouching down. Again we can compare him to Hitler who was the leader of the Nazi party as Jack is the leader of the evil boys on the island. The darkness on the island spreads to every boy like it is within everyone. â€Å"Darkness poured out, submerging the ways between the trees till they were dim and strange as the bottom of the sea† (LOF 62). Before the boys got on the island it was a peaceful island, by acting like savages they spread darkness on the island, which is the evil in each and every one of them. The darkness was submerging or killing any goodness on the island. This is a relevant comparison to the war as well as it killed hope in good people specifically the Jews who were persecuted by another group of people who thought they were better. As darkness overtook the island it also over took Europe during the dark times of World War II. Thus, dark imagery is used to show men can be evil human beings. Golding uses light imagery over the course of the novel to symbolize civilization over savagery. Light imagery is often shown when something good or hopeful is going to occur. The boys make a signal fire in hopes that they will be rescued, â€Å"The flame nearly invisible at fist in that bright sunlight, enveloped a small twig, grew, was enriched with color and reached up to a branch which exploded with a sharp crack†(LOF 45). The fire is a symbol of civilization and hope that they will get rescued which is shown through the imagery used in the quote. The comparison can be made to the civilized people during WW11. They behaved in a way that was good and moral. The English boys on the island are trying to maintain civility by doing things like making a fire. Light imagery is illustrated by portraying Simon with goodness. When he is described Golding uses a lot of light imagery, â€Å"The water rose further and dressed Simon’s coarse hair with brightness† (LOF 169) . When Golding uses words like bright when describing characters it is often because the character is good and civilized, he is often compared to Jesus Christ. Reference to the saviour is associated with hope. Hope is also something that the victims of the Nazi party had to have in order to survive. At the beginning of the novel Golding uses colors and light to describe the character of Ralph as, â€Å"All the shadows on Ralph’s face revered; green above, bright below from the lagoon. A blur of sunlight was crawling across his hair† (LOF 16). Golding uses these colors to describe Ralph because he was one of the more civilized boys on the island. The comparison here can be made to describe Ralph as being good and bright and full of light and Jack as the opposite is dark and evil. To end, it is evident that light imagery symbolizes civilization. The two sides of human nature are evident with the use of dark and light imagery. Imagery is used as a compelling literary technique illustrating how light and dark translates into good and evil. The use of foreshadowing is an indicator of things to come, which was used as an effective tool when referring to light and dark imagery.

I can not help but wonder why they would do this to me. I have been at peace with these humans for many years

For 300 years I have guarded my treasure. My family and I had taken it from a human's town that we once fumed upon. I took my share and placed it on the upland heath concealed in a barrow. No man should have seen it or even caught a reflection of these jewels sparkling in the light of the sun. I was isolated from this world because of what I am, the fire-drake, they call me. When Hygelac was king I did not bother his people often, even when the new ruler came to power for 50 years I did not bother his kingdom. A dirty human then snatched one of my treasure pieces right out of the barrow. The day I came back to my lair I knew something was missing. The precious cup made of gold and jewels had disappeared. Angry and full of rage I set forth to seek out the wretched thief, while returning to my barrow numerous of time to see if my eyes had deceived me. The gold treasure-cup was still no where to be found. I will burn them all to ashes. The fury that I possessed was uncontrollable. I could feel the anger slowly making its why through my body, and until I found the thief I was going to contain it. There were so many of these creatures how was I to know which one had my treasure-cup. They are all alike it does not matter who stole my gold treasure-cup. † Do not think to start anything with these humans Draco,† I turned around to see that it was my father and the leader of my kind, Drace. † You do not understand. I will not let these so called humans take advantage of me.† † It was just one golden treasure-cup that is all!† Why is Drace not agreeing with me? † It is that it was my treasure-cup and they came and bothered me first!† I roared back. † You are on your own then. For if one gold treasure-cup is worth starting a war over then so be it! But let this be known that I will not help you in any way. This is your battle. But let me also warn you of a man called, Beowulf, for he is unlike the rest of their kind.† With that, Drace left, and I was alone once again. The fact that my family was not on my side did not help the fact that I wanted to conceal my anger until the right time. I went out and nearly burned everything to the ground. That was my big mistake for now my barrow was now visible to any eye. I knew that they would soon come after me. I knew that some of these humans were not cowards. I began to prepare myself for the upcoming battle. I did not have much to fear, for my breath could do more harm than all of their swords combined. It still would have felt good to know that I had my family behind me. Shhh.. What was that? I know that they could not be coming for me so soon. Sweat begins to pour from his pores. I must remember that they are only humans. As the barbarians moved up the mound towards me I could see their leader very clearly. For he walked with his head high and look the strongest of all. This must be the man, Beowulf, that my father was talking of. But something about him caught my eye, why he did not look his age, but in his eyes I could tell that he had gone through many winters. Gaining back my confidence I proceeded upon them. Ha! Look at that old fool. Does he really believe that he can defeat me. The leader prepared himself for battle by putting up his shield. Ha! That shield will not protect you old fool. The man Beowulf swung his sword and I roared as it made contact with my body. The strength of this blow was something that I had never felt before. I was sure I had been wounded, but as I look not even a scratch was on me. I'm invincible! The look of shock replaced the courageous expression Beowulf once had. I enveloped him with a huge flame of fire I produced at that exact moment. The other humans with him ran off like cowards towards safety. The leader was left there fighting off the flames. I stopped in rejoiced in my glory, but the second I was going to end his life, the only noble warrior of his pushed him out of my grasp. This man was trying to save his leaders life. He was whispering something to him in a language I could not make out. Roar! I rushed at them and through the flame I could see the man protecting his leader. The leader shaking stood up and swung his great sword-blade and hit my head. Staggering, I saw the sword break. Running towards them I sunk my fangs into the throat of the man, Beowulf. As I turn I felt the blade of another sword. This time there was pain. The other man had drawn his sword upon my body and I was wounded. My vision began to fail and in pain I try to gather my strength back. Beowulf removed an object from his corselet and sharp sensations overwhelmed me.

Determinism essays

Determinism essays The modern philosopher in the quotation argues that Modern science is experimental because it uses the experiment to understand nature. According to him, this is true because nature can be explained by the cause-effect relationship. Modern science uses the experiment to prove events that are assumed to be true in advance. Before conducting the experiment we have assumptions or a theory in mind and we conduct experiment to prove them to be true. The theory itself, determines which experiment should be used and which results will be obtained. We get some results after experimenting, those results feed our theory. Based up on these theories we create new assumptions and from these assumptions a new theory is formed . Again to prove that newly formed theory we conduct experiments according to its own assumptions. Experiment turns into job of looking for answers to questions which come from the theory. Moreover those questions are dependent on assumptions. So we find ourselves in a cir cular reasoning when we are doing experiments. Here, experiment is done to confirm theory. There is no new innovation, we do experiment for finding out whats already there. Therefore, when the writer says experiments are set up for the sole purpose of asking whether and how nature follows the scheme preconceived he shows that he is a determinist and proves that there is a circular reasoning. Because in determinism events are determined by the former events, the pattern is determined. However this logic represents a basic limitation in the scientific description of nature because it excludes the chance factor, flexibility. Nature is not just a cause and effect relationship. To understand why this logic is a limitation to modern science we should examine what are the rules of this philosophy. In determinism the nature is seen as a closed system. In that closed system every event is the effect of the preceding one and at the same time c...

More than 45 000 potential new clients accepted the invitation, and it was a success because the clients bought a motorcycle during the event.

Besides, during the event Supersede Harley Davidson was offering a one-year free membership to a local group of motorcycles.

The top five most important strengths Harley Davidson could have against its competitors are the following: Harley Davidson Strengths Aggressive Marketing Strategies Customers loyalty Strong financial position Social clubs around the world Reputation The first strength to be discussed is the aggressively of marketing strategies that Harley Davidson has had. The company has been taking advantage of its marketing tragedies to overcome its competitors. The fact that Harley Davidson offered a one- year free membership with different promotions like discounts in different places, different type of assistance, maintenance, etc. As a very good idea to attract the public attention. Second, the loyalty of the public to the brand is a strength that Harley Davidson should take into consideration in order to contrast the competence. Asker (1991) defines brand loyalty as symbolizes a constructive mind set toward brand that leading to constant purchasing of the brand over time. Asker (1991) also a rgues that rand loyalty is an essential element when it comes to evaluate a brand in terms of value because loyalty can generate profit (Severe, Refer, Seek Chon Ling, 2013, p. 125-137). Consequently, Harley Davidson should not be very confidence that the loyalty would help the company always. The company must take into consideration the customers opinion, the feedback, in order to create a better motorcycle and get a better performance on its product. The results provide evidence to indicate that a stronger financial position in a previous year is significantly associated with better safety performance in a bequest year (Britton, Roding A, Coors Thomas, 2010, p. 42-51).

8 Great Writing Tips for Kids

8 Great Writing Tips for Kids 8 Great Writing Tips for Kids 8 Great Writing Tips for Kids By Ali Hale I’m 33 now (which feels very old!) but I’ve loved writing since I was a kid myself. The very first story I remember writing was about a mouse, when I was five or six. I spent a lot of time writing stories throughout my childhood, and I had a go at my first novel when I was thirteen. Writing has always been one of my favourite things to do and for the last ten years, it’s been what I’ve done for a living. When I was at school, a lot of the writing I did was as part of my school work. At school, your teachers are probably keen for you to know lots of things about writing – like where to put commas, and what nouns and verbs are, and so on. There are lots of great tips out there about how to get things like that right, and I’ll link to some of those for you in this post. I wanted to focus on some tips, though, about enjoying writing and having fun with it and about becoming a better writer overall (not just a better speller)! Here are my best tips on how to keep growing and improving as a writer, however young you are: #1: Have a go at some writing exercises – you can find lots of these online, or you could have a go at them in workbooks or school books. Lots of adults find writing exercises helpful, too, so that they can get better at writing. You can find some great ones to try here. #2: Read a lot. Almost every writer I know is also a keen reader. Try to read a wide range of different things – like classic story books as well as modern ones, non-fiction (factual) books, magazine or newspaper articles, and so on. You’ll come across lots of different ways to write, and you might learn some new words. #3: Keep a little book of new words you learn. Don’t be embarrassed if you don’t understand a word the first time you read it. Sometimes you can guess from the rest of the sentence what it means, but if not, you can just look it up in a dictionary. You might want to ask an adult how to say the new word, too – you could write down how it sounds. For instance, â€Å"matron† is pronounced â€Å"may-tron† (with a long â€Å"a† sound) not â€Å"mah-tron† (with a short â€Å"a† sound), which is how I thought it was said when I first read it in an Enid Blyton story. #4: Try writing stories for children younger than you, or stories that involve children younger than you. This is a great thing to do when you’re still quite young yourself, because you can remember what it’s like to be six or seven. (Adult writers find it hard to remember, and often they create young children characters who are too babyish for their age.) If you have a little brother or sister, or a younger cousin, you could read your stories out to them. #5: Remember that even adults don’t get things right first time. Sometimes I get a spelling wrong, or I write a sentence that’s confusing for my reader. And I’m a professional writer! It’s fine to make mistakes, so don’t worry about getting everything perfect in your first draft. Just make sure you leave a bit of time to go back and edit afterwards (just like adult writers do) so that you can fix any mistakes. #6: Have a go at different types of writing. When I was young, I like to make pretend magazines or newspapers. That’s something that children have enjoyed doing for a very long time – in one of my favourite classic children’s books, The Story of the Treasure Seekers by E. Nesbit, the children in the story make their own newspaper filled with things they’ve written. Maybe you could have a go at making a newspaper to share with your family and friends – or maybe you’d like to write poetry or a play script, or something else entirely. #7: Keep a journal about your day to day life. There are lots of ways to do this – you could write a sentence or two each day, for instance, or you could write a longer piece once a week. You could write about what you’re learning at school, who your friends are, the games you’ve been playing even what you had for lunch! Details that might seem boring now could be really interesting when you read your journal when you’re 20 or 30 or even 80! #8: Ask for help if you get stuck. If there’s something you don’t understand in what you’re reading, or if you can’t work out if something you’ve written is quite right, don’t be afraid to ask for help. Most adults will be very glad to give you a hand. You could try a teacher, or a librarian (either at your school library or your local library). If you get to meet any adult writers, perhaps through school or at an event, think up some good questions for them too! I hope you have lots of fun with your writing. It can feel like theres a lot to get right, but (outside of school time) the most important thing is that you enjoy writing. I hope the ideas above help you to get even more out of writing.
