Need help with my writing homework on John Steinbeck: His Life and His Works. Write a 1250 word paper answering; Steinbeck’s books generally deal with the desperation and resilience of poor Americans in the early decades of the twentieth century.

His outstanding literary life culminated with the conferring of Nobel Prize for Literature in 1962, four years before his demise (Palmer, 2001, p.479).

It is fashionable with the new breed of novelists to separate literary art from political themes. But in the case of John Steinbeck, this distinction is not evident. The author, in the process of creating a work of art, had also taken upon himself to ask questions of social injustices in general and economic disparities in particular. Hence, Steinbeck’s body of work is in essence full of his own perspective on the state of rural American society. the medium of the novel is chosen in only as far as it gives the author requisite scope and opportunity to fulfill his role as a social commentator. To understand this social activist trait in Steinbeck’s character one has to look at the experiences and circumstances that shaped his vision of America. Firstly, his years as an adolescent in Salinas, where he got a firsthand experience of his parents’ struggle for survival is a formative influence. It is the next phase of his life however, that will prove more important – his long-time relationship with the radical social worker Carol Henning. The influence of Carol Henning cannot be underestimated, for her socialist views on life had clearly rubbed off on Steinbeck, which is evident from the earliest journalistic assignments that Steinbeck undertook. His years as a novice journalist also had a key role in the shaping of his character, for these early writing assignments were the foundations for his later literary pursuits (Palmer, 2001, p.479).&nbsp. &nbsp.

writing homework on Some Issues in Molecular Cell Biology. Write a 1250 word paper answering; Membrane lipids possess a critical common structural theme: membrane lipids are amphipathic molecules (amphiphilic molecules), most of which form bilayers. Membrane lipid contains both a hydrophilic (water-loving) and a hydrophobic moiety.

Need help with my writing homework on Some Issues in Molecular Cell Biology. Write a 1250 word paper answering; Membrane lipids possess a critical common structural theme: membrane lipids are amphipathic molecules (amphiphilic molecules), most of which form bilayers. Membrane lipid contains both a hydrophilic (water-loving) and a hydrophobic moiety. In essence, hydrophilic molecules dissolve readily in water because they contain charged groups or uncharged polar groups that can form either favorable electrostatic interactions or hydrogen bonds with water molecules. Hydrophobic molecules, by contrast, are insoluble in water because all, or almost all, of their atoms, are uncharged and nonpolar and therefore cannot form energetically favorable interactions with water molecules.

Compose a 1250 words assignment on perception investigation: common misconceptions of highway safety.

Compose a 1250 words assignment on perception investigation: common misconceptions of highway safety. Needs to be plagiarism free! Now let us talk about perception-reaction time. This is how long it takes a person to react in a situation, for example, in driving. Although some people have tried, there are no definite seconds or minutes to measure a person’s reaction. Even if there is, it would vary depending on the person and other variables. When talking about perception-reaction time, please remember three things: thinking, acting, and the device.

Let’s say you and I are both driving our cars on the same road but towards each other. Before you react and avoid me, your brain goes through several mental stages. This is the thinking stage. First – detection. Your brain recognizes there is a shape before you. Second – identification. Your brain cells tell you the shape is another car with its driver. Third – Mentally, you take in the scene. You and I are going to collide. Fourth – You decide what to do. All these four things must be done mentally in a matter of milliseconds. Remember you still have to react.

Now that the thinking stage is done, let’s discuss how you will react. Of course, your initial reaction would be to avoid me. However, that takes several movements on your part such as lifting your foot off the gas pedal, putting both hands on the steering wheel, etc. These would also need to be executed in just milliseconds.

The Other Wonders of the World. The work is to be 5 pages with three to five sources, with in-text citations and a reference page.

I will pay for the following article The Other Wonders of the World. The work is to be 5 pages with three to five sources, with in-text citations and a reference page. One of the remarkable architectures of this era is the Swiss Re tower. Its aerodynamic shape which looks like a pinecone has been given a nickname ‘the Gherkin’ by the residents of London. Because of its shape and structure, it is called the 1st environmental office building. Its architect Norman Foster wanted to create a skyscraper that was in harmony with nature. This is the main reason for this oddly shaped pinecone building. The aerodynamic design of the building allows the wind to flow around its surface generating pressure difference and thus natural air ventilation inside the building is produced through wind tunnels that have been designed specifically for this purpose.

The building structure is a double-curved geometry. The Gherkin is structured in such a way that the office space is 450,000 square feet. To build the complex architectural design of the building parametric modeling was used. It has a “circular plan that widens as it rises from the ground and then tapers towards its apex” (Great Buildings). To build this tall tower, a grid of diagonally intertwined steel fundamentals was used as a central core and perimeter. The main reason behind using this was to create triangular structures with diagonal support beams (diagrid) which would act as a load-bearing facet. By using the diagrid, an interior space was created that had no column support. Due to the diagrid, the exterior look of the building was given using thousands of glass panels.

To enter this enormous office building, triangular archways have been made in the structure.

Lloyds Building is another remarkable modern structure of the City of London designed by Richard Roberts. Richard’s design is the most brilliant anyone has seen. It is a combination of an old building and a new building with the use of modern technology. It is a 12 story building which has now become the most controversial architectural topics in the UK. The Lloyds building marks the beginning of a new industrial revolution that is backed by modern technology. The building has 3 main towers and 3 service towers.

write an article on Pygmy Rabbits. It needs to be at least 1250 words. Pygmy rabbits are among the unique creatures mainly found in North America. They are the smallest of all rabbits found in North America.

Hello, I am looking for someone to write an article on Pygmy Rabbits. It needs to be at least 1250 words. Pygmy rabbits are among the unique creatures mainly found in North America. They are the smallest of all rabbits found in North America. The mass of a pygmy rabbit is approximately half the mass of a normal mountain cottontail rabbit. The adult males and females differ in size where adult females are larger than the male pygmy rabbits. In appearance, pygmy rabbits are mostly confused with juvenile cottontail rabbits but pygmy rabbits have several distinctive features. Unlike all other rabbit species in Utah, pygmy rabbits have the uniform brown coloration of tails. In addition pygmy, rabbits have small and neutral-colored tails that may give an impression of these rabbits being tailless.

Pygmy rabbits are listed among the endangered species in the world (Washington Department of Fish and Wildlife, 2013). These rabbit species have a large number of predators that kill and consume them. In addition, pygmy rabbits are small and slow in avoiding predators thus ending up being captured and killed. Therefore, species of pygmy rabbits should be conserved to ensure that these species are not extinct over time. Research is one of the appropriate strategies that can be used to conserve the endangered species effectively.

Research on Pygmy rabbits is necessary in order to identify various features, habits, survival traits, and habitat requirements of pygmy rabbits. The study on pygmy rabbits will cover important information such as morphological description, taxonomy and distribution, habitat and habitat requirements, activity and movement patterns, survivorship and reproduction, food habits, population demographics, and conservation plans. A study of these areas will enable different conservation bodies and governments to adopt various strategies in order to conserve pygmy rabbits.

Body

The study on pygmy rabbits will involve acquiring morphological description. Morphological information required in the study will be based on the structure and forms of the pygmy rabbits. The morphological description will include size, average weight, color, total length, unique features, and habits of the pygmy rabbits. Morphological information should cover all the structural aspects of the pygmy rabbits.

Write 5 pages thesis on the topic evolution of the horse. Hyracotherium, the earliest relative of the modern horse lived 55mya, during the Lower Eocene epoch.

This paper shall focus upon major genera of the supposed line of ancestral descendants from Hyracotherium to the modern horse. No references are made to tangential genera.

Hyracotherium: The genus Hyracotherium lived during the lower to middle Eocene. It was a small dog-sized mammal with four toes on its forefeet and three on the rear. It had low-crowned teeth with horse-like ridged molars. The face was short with centred, forward facing eye sockets and a short distance between the front and cheek teeth [diastema]. Its physical characteristics suggest that it inhabited forested areas and browsed upon foliage (Garner, 2005. Tufts University, 1998).

Orohippus: Appears during the middle Eocene, circa 2mya after Hyracotherium and existed from 52-45mya. It is believed that Orohippus evolved from a species of Hyracotherium but different species from the two genera co-existed during this epoch. Orohippus characteristics were much the same as Hyracotherium bar the vestiges of the 1st and 2nd toes, which vanished (Tufts University, 1998. Hunt, 1995).

Epihippus: Appears 47mya in the middle Eocene. Epihippus characteristics were alike the previous genera bar a continuing evolution of the teeth. The rear premolars had evolved to become like molars, suggesting that the Epihippus was eating more hard foliage (Hunt, 1995).

Mesohippus: Mesohippus was a sheep-sized descendant of the Orohippus that became extinct sometime in the middle Oligocene and lived circa 37-32mya. It too was a browsing animal with low-crowned teeth but had evolved to have only three toes on its forefeet. Its cranial capacity had also noticeably increased (Hunt, 1995).

prepare and submit a paper on colorimetric determination of salicylate in urine. In plants, salicylate is used as a natural pesticide. In treatment, salicylate is used in the treatment of moderate to mild pain.

Your assignment is to prepare and submit a paper on colorimetric determination of salicylate in urine. In plants, salicylate is used as a natural pesticide. In treatment, salicylate is used in the treatment of moderate to mild pain.

The most commonly known salicylate is aspirin. Aspirin has been extracted from willow bark. Initially, during its introduction, aspirin was considered to be very safe in treatment but in recent times, there have been numerous side effects that have been documented. These include such things as gastrointestinal effects, respiratory effects, hearing loss, fecal and urinary incontinence, salicylate induced hypoglycemia, and toxicity of salicylate in breast milk (Cavanaugh & Bambenek, 1976). Despite the known effects of the salicylate, there are numerous cases where salicylate is being used to treat various diseases. Moreover, there are numerous cases of poisoning that are prevalent in children and adolescents.

Considering the fact that a large number of people are consuming the drug either knowingly or unknowingly, the determination of salicylate in the human body is paramount to facilitate proper prescription treatments. Colorimetric determination of salicylate in urine is one of the methods used in the determination of salicylate in the human body. In this method, the presence of the compound is determined together with its concentration (Shaw, 2011).

15.00 cm3 of synthetic urine sample was then pipetted into another 25.00 cm3 volumetric flask and 2.50 cm3 of iron III added to the solution. The solution was then made up to the mark of the volumetric flask using distilled water. All the solutions were then stoppered, mixed thoroughly and then left to stand for five minutes.

Using beer lamberts law, the concentration of salicylate can be easily determined (Shaw, 2011). The determination of the concentration of salicylate can be determined in ways. Ways using the beer lamberts law. If the molar absorptivity of a solution at a given wavelength is known, the concentration is calculated directly using the beer.

I need help creating a thesis and an outline on Properties and Applications of Ceramics, Fibres and Plastic. Prepare this assignment according to the guidelines found in the APA Style Guide. An abstract is required. The basic arrangement of these crystals and the presence of impurities determine the resulting material. The final product has slightly different characteristics.

Properties: They are stiff, strong and hard in properties. They are resistant to scratches. Ceramics attracts fluids on their surface as they have low frictional resistance. The main disadvantage of medical ceramic materials is that they are fragile. They are resistant to heat. They are able to stand the heat and retain their shape when subjected to intense heat. However, when the limit of stress exceeds, the ceramic material bursts and explodes into many splinters.

This is made up of small crystals of aluminum oxide. The impurities within alumina ceramic are less than 0.5% in the material’s volume. The modern ceramic crystals of the aluminum oxide are relatively tiny and densely packed together. This type of close packing of aluminum oxide crystals is achieved by applying Hot Is-static Pressure. The ceramic component is re-heated and then subjected to intense symmetric pressures.

Most ceramics today are tough and hard. The final product’s strength is dependent on the size of the crystals. The smaller the crystals the purer the materials tend to be. The impurities make the ceramics weak and prone to fracture cracks. The coarse structure and the impurities are the cause of the frequent fractures in the old ceramic components.

The modern Alumina ceramic balls are extremely tough in their structure. They are tougher than the metallic stem on which they based. Alumina ceramic ball has the ability to sustain 60 times the weight of the average patient. This is one big reason why it is often used in hospitals.

Composition: This is made through coarse aluminum oxide crystals and clay i.e. silica oxide mixed together and heated on fire. They make the bases of commercial ceramic materials, for instance, the china cups.
