Model of Essential Amino Acid Essential amino acids are those amino acids in which the body can not make on its own, instead they must be procured through the foods that we eat (Helmenstein). Lysine is one of the essential amino acids. Two of the chemical properties of lysine are that it is positively charged and it is hydrophilic, which means water loving so it easily dissolves in water (National Center for Biotechnology Information).

The Four Forces that Stabilize Proteins at Tertiary Level

The tertiary structure of proteins are dictated by several factors. Non polar molecules are also hydrophobic and they tend to gravitate towards the center of a protein structure, where there contact with water is minimized. In addition the polar (hydrophilic) R groups tend to want to congregate towards the outer aspects of the protein structure. A weak force occurs when there are tightly packed non polar R groups inside the protein, this is called Van der Waals interaction.

...Task 2 A Mahatma Gandhi was born in Porbandar, Kathiawar, India on October 2, 1869, in. After studying law in London, England, he left for South Africa in 1893, where he spent twenty years fighting biased legislation against Indians. As an innovator of passive opposition of mass non-violent civil defiance, he turn out to be a major political and spiritual leader ( 2013). In 1914, Gandhi went back to India and became the leader of the Indian National Congress and gave his support the Home Rule movement, furthermore advocating a strategy of non-violent non-cooperation to attain independence. Gandhi’s main objective was to assist poor laborers and farmers protest discriminating taxation and prejudices. His struggled was to liberate women, ease poverty, and stop class discrimination. Mahatma Gandhi main goal was for India to rule itself ( 2013). Mahatma Gandhi spent two years in jail, from 1922-24, for conspiracy. In 1930, he marched 200 miles to the ocean to gather salt to show defiance to governmental control. Gandhi sat at the London Round Table Conference in 1931, regarding Indian constitutional reform. In 1946, he negotiated for a new constitutional structure with the Cabinet Mission. In 1947 after the independence, Gandhi worked to stop the Hindu-Muslim conflict in Bengal, which eventually caused his assassination ( 2013). Mahatma Gandhi's pledge to non-violence and conviction to simple living has been an inspiration of hope for......

...for the largest Christian church in Egypt and the Middle East. The foundational roots of the Church are based in Egypt, but are now worldwide. The church was established by Saint Mark, an apostle and evangelist, in the middle of the 1st century. Coptic Orthodox Christianity started in Egypt but has become worldwide and has become a common faith around the world. Egypt is identified in the Bible as the place of refuge that the Holy Family sought in its flight from Judea: "When he [Joseph] arose, he took the young Child and His mother by night and departed for Egypt, and was there until the death of Herod the Great, that it might be fulfilled which was spoken by the Lord through the prophet, saying, Out of Egypt I called My Son" (Matthew 2:12–23). The word Copt is derived from the Greek word Aigyptos, which was, in turn, derived from "Hikaptah", one of the names for Memphis, the first capital of Ancient Egypt. The modern use of the term "Coptic" describes Egyptian Christians, as well as the last stage of the ancient Egyptian language script. The word ‘orthodox’ literally means ‘straight opinion.' The Coptic church is based on the teachings of Saint Mark , he brought Christianity into Egypt during the roman era when Nero was emperor. Christianity spread throughout Egypt within a half century of Saint Marks arrival in Alexandria. According to the tradition when Saint Mark arrived on his missionary journey to Egypt he found that the Coptic religion was a god centered......

Describe the “old” and “new” means of classifying bacteria. Old is by shape. - Monera Second is by size, color, and chemical composition. - archaea and bacteria are new eu bacteria is the new kingdom 5. What is the structural difference between eubacteria and archaebacteria? The general cell structure of archaea and bacteria are the same but composition and organization of some structures differ in archaea. Similar to bacteria archaea do not have interior membranes but both have cell wall and use flagella to swim. Archaea differ in the fact that their cell wall does not contain peptidoglycan and cell membrane uses ether linked lipids as opposed to ester linked lipids in bacteria. 6.

Task 2

...Task Stream 2 Microbiology can be broken down into categorizations based upon the environmental conditions necessary for organisms in which to grow. Two large categories of microorganisms are those requiring oxygen to live (obligate aerobes) and those which can grow with oxygen but have the ability to also grow without it (facultative aerobes). The obligate aerobes produce more energy from nutrients than anaerobes by using oxygen as the “final electron acceptor in the electron transport chain, which produces most of the ATP in these organisms”(Betsy & Keogh, 2005, p.104). The facultative microorganisms are able to use oxygen but can also go without by using fermentation or anaerobic respiration when it is not available (Betsy & Keogh,2005). The microorganisms being cultured in our first task (Lactobacillus acidophilus and Staphylococcus epidermidis) are obligate aerobes. Microorganisms can grow in a variety of conditions with temperature being one of those variables, but the types we frequently encounter in our environment thrive in fairly warm temperatures. Both Lactobacillus acidophilus and Staphylococcus epidermidis are examples of these, which are referred to as mesophiles. Extreme temperatures (as in deep freezing or auotoclaves for example) are effective in destroying microorganisms due to their inability to thrive outside of more moderate temperatures). Growth of these two organisms would be optimized by remaining between 25 and 40 degrees celsius (Betsy...

...Task 2, Community Health (C228) Edward Croston Western Governors University Task 2, Community Health (C228) MEASLES Measles was at one time in the not too distant past, a killer of those that became infected. Measles has been around for centuries. The first published, written account of the disease was in the ninth century by a Persian doctor. According to the Centers for Disease Control and Prevention (CDC) website on measles, it was not until 1757 that a Scottish physician, named Francis Home, proved that something infectious in the blood was causing the disease. By the early 1900’s, the United States began requiring every healthcare provider and laboratory to report all identified cases, with approximately 6,000 deaths being related to measles each year. Almost all children contracted the disease by the time they were the age of 15, with an estimated yearly infection rate of three to four million United States citizens. Each year, it is estimated, 400 to 500 people died from measles, 48,000 hospitalized, and 4,000 developing encephalitis as a side effect of the disease. The measles, mumps, and rubella (MMR) vaccine was made available to the public in 1963. The MMR has significantly reduced the reported cases of measles. In the year 2000 measles was declared eradicated in the United States. But since then, the disease has returned from time to time. ("Measles History," 2014, p. 2) Measles is a virus that has an incubation period of approximately 14 days. It is......

...Kirvon Butler 000-07-7713 BIO 109 Haemostasis and blood clotting: Preventing deep vein thrombosis The body’s ability to control the blood flow after sustaining an injury is essential to continued survival. Haemostasis is the process of blood clotting and then the dissolution of the clot after the injured tissue is repaired. Haemostasis comprises of four major events that occur in sequence following the loss of vascular integrity. 1. The first phase of the process is vascular constriction. The blood flow around the injured area is limited. 2. Next, platelets become activated by the enzyme thrombin and cluster around the injured area, forming a loose platelet plug. The protein fibrinogen is responsible for stimulating platelet clumping. Platelets clump together by binding collagen that becomes exposed after the rupture of the endothelial lining of vessels. Once activated, platelets release the nucleotide, ADP and the eicosanoid, TXA2 (both also activate additional platelets), serotonin, phospholipids, lipoproteins and other proteins important for the coagulation cascade. Along with the induced secretion, activated platelets also change their shape to assist in the formation of the plug. 3. To ensure that the initially loose platelet plug is stable, a fibrin mesh (clot) forms and encases the plug. If there are only white platelets in the plug it is called a white thrombus. If red blood cells are present it is called a red thrombus. 4. Lastly, the clot......
