Need help with my writing homework on Questions concerning Biology. Write a 1500 word paper answering; Free radicals do have the ability to arise in the non-enzymatic reaction when oxygen reacts with organic compounds. Ionizing radiation may also give rise to free radicals. Some internally generated sources of free radicals are peroxisomes, exercise, mitochondria, inflammation, phagocytes, arachidonate pathways, reperfusion, and reactions which include iron and other transition metals (Sotgia, et al., 2014).

It is a well-accepted fact that the incidence of disease increases with age. A reasonable explanation regarding the association of disease and age is related to the implication of free radical reactions taking place in the pathogenesis of several disorders. Free radical reactions produce progressive negative changes in an individual that accumulate with age throughout the human body. Such “normal” changes are common in all individuals. However, the formation of free radicals is also controlled by patterns influenced by environmental and genetic differences modulating free radical damage (Rahman, 2007).

Ample evidence is present regarding the fact that diseases at a specific age are determined by environmental and genetic factors. Atherosclerosis and cancer, the two major conditions of death are considered to be the result of the free radical disease. The initiation of cancer is usually associated with oncogene activation and chromosomal defects. The white blood cells present in the human body release free radicals for the purpose of destroying the invasion of pathogenic microbes. Hence free radicals are not always harmful. They do serve for a useful purpose in the human body (Bahorun, et al., 2006).

As individuals age, their arteries begin to harden and get narrow naturally, which leads to atherosclerosis (Castillo-Richmond, et al., 2000). However, there is a number of factors such as alcohol, family history, ethnicity, and air pollution that accelerate this process.&nbsp.

Cholesterol is a kind of fat that is essential for the functioning of the human body. It helps in the production of hormones and protects the ending of nerves. Most of the essential cholesterol required by the body is manufactured by the liver. However, when an individual intakes food rich in saturated fat, the fat gets broken down into LDL, which is considered to be bad cholesterol. Foods that are rich in saturated fat are cream, butter, cakes, sausages, bacon, biscuits, and processed meat. The LDL sticks to the artery wall of an individual as fat deposition, which with time reduces and buildup blocking the supply of blood (Anon., 2013).

Need help with my writing homework on Oxidative Phosphorylation and the Electron Transport Chain. Write a 2500 word paper answering; As the ATP synthase molecule rotates further by 120 degrees the bound ATP occupies the open site or O site from where it is released from the Open site (Yoshida et al, 2001). As the newly formed ATP comes into the mitochondrial matrix there is another transporter located in the inner mitochondrial membrane called the ADP/ATP transporter (Leys and Scrutton, 2004). This transports the ATP formed from the mitochondrial matrix to the cytoplasm and at the same time antiports the transport of ADP into the mitochondrial matrix to become bound to the open site, then loose site and once again to the Tight site where it binds with Pi (carried into the matrix by Pi transporter) and forms ATP again. This is the way the cycle continues by ejecting out ATP into the cytoplasm and at the same time inflowing ADP for the next cycle of ATP synthesis. Since ADP is not present, hence it does not go through this antiporter (protein molecules that help to move two substrates in different directions) to form the new cycle of ATP. Hence when ADP was not there, no antiport occurred however when the ADP was replenished the oxidative phosphorylation returned to normal as ADP entered through the antiporter in exchange of ATP to start the new cycle of ATP synthesis by oxidative phosphorylation(Yoshida et al, 2001).

Mostly during the tricarboxylic acid cycle and beta-oxidation of fatty acids the pyruvate and malate can become oxidized by NAD+- dependant dehydrogenases because these enzymes are able to transfer electrons from these substrates to the NAD+ owing to their lower redox potentials or the electron transfer potentials than the NAD+ because of the prevalence of the concentration of the molar oxidant/molar reductant ratios of these substrates and of the NAD+ in the mitochondria. Oxidation-reduction comprises of the flow of the electrons between the two redox couples which differs in their affinity for electrons (Calhoun et al, 1994). Hence electrons&nbsp.flow from the reductant ( pyruvate or malate) to the oxidant of another redox couple which is NAD+ in this case. Thus NAD+ gets reduced to NADH2 which further transfers the electrons through ubiquinone, cytochrome C to donate it finally to the oxygen molecule which is the ultimate terminal electron acceptor in the mitochondria, this generates free energy which is utilized to synthesize ATP from ADP and Pi.&nbsp.

research paper on problems faced in establishing sustainable tourism projects on islands. Needs to be 6 pages.

Need an research paper on problems faced in establishing sustainable tourism projects on islands. Needs to be 6 pages. Please no plagiarism. Different countries, as shown in the diagram below experience different volumes of tourist, hence the tourist spending and the generated income is different.

A close look at the tourism arrivals and income generated in the U.K shows that there is a declining trend (Euromonitor, 2013). The diagram below shows the aforementioned declining trend in U.K tourism. The trend is similar for the earnings from tourism and for the number of tourists visiting the U.K.

It is important to understand that there are different ways in which islands can be classified, mostly based on their characteristics and hence the challenges are all different (Sheldon, 2005. Dodds and Graci, 2012). One characteristic that distinguishes islands is how close or far they located to or from the mainland. Those located into more remote and far areas from the mainland have a greater degree of challenges compared to those located close to the mainland (Sharpley, 2009). The advantageous difference between the two those in the interior has a higher number of tourists who stay for longer as compared to those in the mainland and which register one or two days visitors. Cousin Islands located in Seychelles are an example located near the mainland and which does not have many stay-over visitors (Sheldon, 2005).

Another differential characteristic is based on the climate of the islands. Some such as Hawaii and French Polynesia experience tropical and cold climates whereas others such as the Shetland Islands have temperate climates (Aguilo, Alegre and Sard, 2005). The other categorization is based on the homogeneity and composition of the population in the islands. Islands with an aboriginal populace are vulnerable to tourism effects as they are not accustomed to foreign values. Those with a more heterogeneous populace are usually pliant to socio-cultural impacts (Sheldon, 2005. Harris, Williams and Griffin, 2012).

Writing paper on american music genres history

I need some assistance with these assignment. american music genres history Thank you in advance for the help! Rhythm and blues is the name given to the genre of African American music in the 1940s used by record companies. This term was mainly used for blues music which is a form of music originated from the African American communities in the 19th century. This music form came from work songs, spirituals, field hollers, chants, and shouts. They also consisted of narrative ballads. Blues music is characterized in rhythm and blues, rock and roll, and jazz by some specific chord progressions. The twelve-bar blues is the most commonly used chord progression. Blues music has special lyrics, instruments, and bass lines, and they are sung for expressive purposes (Nicholls 352). Louis Jordon dominated the rhythm and blues charts in 1948 with his songs that were made on boogie-woogie rhythms. ‘Pinetop’s Boogie Woogie’ was one of his hit numbers.

Folk music genre evolved in the 20th century as the folk revival since it comprises of traditional music which was much older. By the mid-twentieth century, folk music was recognized as a new form of popular music and this era was called the revival of folk music. The revival of folk music consists of other forms too such as folk metal, folk-rock, and electric folk. However, the performers and the songs were a blend of traditional and contemporary folk music (Nicholls 288). This music genre was often related to culture, history, personal events, and was performed for years, at times for generations. Woody Guthrie was from the first musicians to revive folk music whose legacy includes hundreds of compositions. ‘This Land is Your Land’ is his best-known song.

Country music originated as a form of American popular music from the rural areas of Southern United States. The roots of this style are taken from Western music and American folk music. Country music consists of dance tunes and ballads with simple harmonies (Nicholls 356).

I need some assistance with these assignment. a reflective learning log book Thank you in advance for the help! My lecturer was brief and clear and demonstrated all the skills that were required to acquire a good study habit. In her lecture, there were demonstrations, reading and writing notes. I found the lesson to be quite interesting as the topic we were learning touched my area of weakness, and from there I knew what to do in order to improve and develop a good study habit.

In this lecture, I learned about critical thinking and reading skills. In the first part of the lesson, the lecturer defined the term critical reading, as in-depth reading and analysis of what the reading material states. Initially, I always read books and academic materials very partially and recklessly. However, from the lecture, I realized that it was not the best way of reading. therefore, I learned that I needed to sharpen and improve on my skills of reading and learning, in this case, I had to learn and implement the new reading skills that would lead to a good performance. After learning this, found my reading of the books very easy and very effective. For instance, in my course, of study that I am currently taking, I realized that I needed to read the whole chapter in order to grasp the theme of the book, this helps me to gain more knowledge and the concept of the topic am reading about. According to my lecturer, critical reading involves in-depth reading and analysis, therefore through this knowledge. I realized needed to critically and analyze the topic from the chapter that I was reading. However, it is not always easy for me, since I find the sentences to be long and complicated as well as somehow hard to comprehend. For instance, the topics of politics and business, some of the topics from these are somehow hard to analyze and comprehend.

According to the lecturer, when we read we need to write down short notes on what we are reading.&nbsp.

prepare and submit a paper on the destabilization of homosexuality and heterosexuality in film.

/in /by

Your assignment is to prepare and submit a paper on the destabilization of homosexuality and heterosexuality in film. It has the assertion that heterosexuality is the only sexual norm, and that marital and sexual relations only fit between people of opposite sexes. There are however critics who argue that heteronormative attitudes are stigmatizing, marginalizing and oppressive of deviant forms of gender and sexuality. These deviant forms of sexuality include bisexual, gay, lesbian, transgender and intersex people. Heteronormative culture fosters a climate in which these deviant forms of sexuality are discriminated against in the workplace, marriage and even tax codes. There has been strong opposition to such discriminations and a lot of movements and advocacy outfits have been formed to ensure that people with such traits are treated with dignity in our societies.

In the article introducing the new queer cinema, there were concerns about the rise in films that were themed on these deviant lifestyles (Gever, M. 2010). There were serious concerns that the reason such movies were trending in the 1980s was to bring out such deviant lifestyles as things that people needed to treat with contempt. The manner in which they were portrayed in certain movies was to ensure that people looked at the deviants as people who weren’t supposed to live in their midst. Such movies were seen to be radical in form, and aggressive in the manner that they presented sexual identities the conservative perception of heterosexuality.

Such movies resisted the promotion of gays and lesbians positively. This was in spite of the fact that there had been liberation movements and advocacies that had given a little space for those who had such deviant sexual orientations. These movies instead presented the gay, lesbian, intersex, bisexual and transgender forms as outsiders and renegades from the rules that prescribed what a conventional society was.

Create a 7 pages page paper that discusses visual cultural and theory: graphic design, technology and politics. Even though the animation is associated today with computers and advanced technology, it began much before than anyone has ever predicted. Instances of animation have been observed as early as during the prehistoric times when archeologists discovered figures drawn in a series of successive motions on cave paintings. A 5,200-year-old animation has also been discovered on an Iranian bowl. Similarly, early versions of animation have been discovered in Egyptian art also.

Leonardo Da Vinci, the great Italian mastermind had also experimented with animation. In his folio, the Windsor Collection, Da Vinci attempted to portray the human body in a series of sequences which implies the use of animation. However, like many other Da Vinci sketches, this one also was done much before the right technology was available.

The first technology to incorporate animation was a television with its standard picture film. J. Stuart Blackton, the father of American animation, released the first animation film in 1906 titled Humorous Phases of Funny Faces where the image sequence was drawn on a blackboard and presented in succession to create the illusion of movement. Later in 1908, Fantasmagorie, a stick figure animation film was released. In this film, the images were drawn on a paper and later shot on a negative film. These were rudimentary animation films where often the animator’s hand was visible but despite this, they required great talent and creativity since they were executed in a time when computers were not available to store or modify characters.

Later with the release of the cinematograph, the technique of stop motion made animation more interesting. With the release of Haunted Mansion by Blackton in 1906, animators were able to interest and inspire the viewers in the way they were able to master the technique of animation.

Create a 12 pages page paper that discusses fifa world cup brazil 2014. Till now, 19 World Cup championships have been awarded to eight different national teams including Brazil, Italy, West Germany, Argentina, Uruguay, England, France, and Spain. Each World Cup is hosted by a different country, and the FIFA has a set of stated prerequisites for hosting the World Cup with regard to infrastructure and other facilities. While analyzing the event typology, it seems that the FIFA World Cup is a sporting event that is broadcasted across the globe. The FIFA World Cup is the world’s most widely viewed sporting event. the final match of the 2006 FIFA World Cup has been watched by an estimated 715.1 million people (Dwivedi, 2011, p.6.75). Brazil is the most successful team in the history of the FIFA World Cup-winning a total of 5 titles. The last World Cup was held in South Africa in 2010 and the 2014 World Cup will be hosted by Brazil.

Before the beginning of the FIFA World Cup, the Olympic football tournament had been the only international tournament or world football tournament. With the founding of FIFA in 1904, there were serious discussions on arranging an international football tournament between FIFA member nations outside the Olympics. However, these efforts had not been successful for the next two decades. With the FIFA President Jules Rimet’s great efforts and dedication, discussions again started in the late 1920s to organize an international football tournament outside the Olympic framework and as a result in 1928, the FIFA Congress in Amsterdam decided to organize its own world championship. FIFA choose Uruguay as the host country for the inaugural World Cup tournament which was held in 1930.

Since tourism is a potential way to build a better future for an economy, it can be stated that the aims of the World Cup reflect the tourism role that the event has. The wider tourism concept represents people visiting domestic places.

Need help with my writing homework on Workplace Conditions Production History. Write a 1750 word paper answering; Brad Pitt, acting as Sergeant Collier, leads the group of five men in a tank throughout the movie engaging in a number of despairing battles with the Germans along the road and in cadaverous fields. When the crew are not in the battlefields, they take time and relax, clearing their thoughts away from combat by engaging in interesting conversations, praying and generally enjoying each other’s company. nonetheless, such scenes are very few and temporary as compared to the rest of the time. In the battlefield, there is a lot of activity with bursts of flames, a glowing flight of shells and bullets, and of course, the mixed clouds of white, brown and grey depending on the depth of battle. Generally, Fury is a primitive movie that incorporates war horror and exquisite combat. appreciably, its launching was on October 17 and so far it has had many good reviews and ratings so it might not come as a shock if it is among the movies of the century.

Decisively, unlike most of the past World War 2 films, most people label this movie to be the best one so far because the directors and producers go an extra step of making the film more realistic. The director of the movie is a war veteran operating one of the tanks in the 1980s, hence he uses the movie to express the critical aspects of experiences. moreover, the cast of the movie is based on characters that Mr Ayer served with, people that were more of a family than tank-mates. However, the movie does not revolve on the director’s experience alone but it also incorporates the last days of WW2 and a few details from other veterans and books. The attires and munitions used in the film are authentic and similar to those in the war. appreciably, the tank in the movie is the most captivating especially when one gets to know that it is an original used in the war by the Germans.

Concurrently, the setting of the movie is unique and the production makes it very interesting. moreover, there is a lot of originality and legitimacy in Fury with the director using history as the basis of his script.&nbsp.&nbsp.
