HAV: This virus spreads by fecal oral. The vaccine is given to protect against inflammation of the liver caused by the virus and if not treated it can cause jaundice, abdominal pain and fatigue. If not taken care of, the patient can develop acute renal failure or may require a liver…
Triglycerides are broken down to free fatty acids and monoglyceride by lipase. Bile salts bind to lipids which help transport them in the small intestine. In the small intestine colipase help expose lipids to lipase for further breakdown to micelles. These small lipids can now enter the apical membrane of the small intestine and form chylomicron which then are released into the lymphatic system or small lipids can enter the circulatory system.…
The plasma membranes are made up of proteins that form pores and channels, cholesterol to provide membrane stability and carbohydrate molecules for cell recognition. The most abundant component found in the plasma membrane is the phospholipid, which is bilayer. The plasma membrane is amphipathic that include both hydrophilic heads and hydrophobic tails. The head is polar and the tail is non-polar. The plasma membrane is what they call a mosaic of lipids, proteins and carbohydrates. Active transport is within the cell membrane which requires the use of energy and moves molecules from low to high concentrations using protein carriers. The transport are made up of pinocytosis, phagocytes, receptor mediated endocytosis, exocytosis and transcytosis. Pinocytosis is when cells take in tiny droplets of liquid from their surroundings. Phagocytes are white blood cells that take in solid particles such as bacteria and cellular debris, this helps fight off injections or diseases causing microorganisms. The receptor-mediated endocytosis will only let certain particles into the cell, only allowing cells with the appropriate receptors to remove and process its surrounding even in very low concentrations. Exocytosis is a substance that’s placed into a vesicle and comes together with the cell membrane which releases the contents outside of the cell. The cells secrete proteins this way. Last is the transcytosis which combines both the endocytosis and exocytosis to transport substances from one end of the cell to the other, which is also…

In his essay "The Myth of Immortality," Clarence Darrow explains his belief that life after death is a hoax and backs up his logic with logical reasoning. Darrow finds it hard to believe that life exists after death simply because there are no facts to prove that it exists. He states that "if people really believed in a beautiful, happy, glorious land waiting after death why don't they hasten themselves to it." Darrow also shows his discern in his views for the soul questioning that if we do have a soul, when is it created in the natural process of reproduction? He also questions "If a man has a soul that persists after death, that goes to a heaven of the blessed or to a hell of the damned, where are those places?" Moreover, he goes into detail and explains his reasoning against the resurrection of the body. He states the mere thought of such ideas beggars reason, ignores facts, and enthrones blind faith, wild dreams, hopeless hopes, and cowardly fears as sovereign of the human mind, despite the fact the bible clearly states that Jesus has risen from the dead and ascended into heaven. Darrow moves on into the scientific reasoning stating that people take comfort in the law that matter and force cannot be destroyed, meaning their soul lives on forever. Darrow continues and says that there is no proof that memory and consciousness exists after death. Even more, Darrow continues with his statement "We are assured that without faith, life is only desolation and despair." Or in other words, Darrow says that people "create" a place that exists after death in order to ease the natural fears. In conclusion Darrow states "we should be more kind to each other and make our lives easier for we live a common life and die a common…
"Segu is a garden where cunning grows. Segu is built on treachery. Speak of Segu outside Segu, but do not speak of Segu in Segu" (Conde 3). These are the symbolic opening words to the novel Segu by Maryse Conde. The kingdom of Segu in the eighteenth and nineteenth century represents the rise and fall of many kingdoms in the pre-colonial Africa. Therefore, Segu indirectly represents the enduring struggles, triumphs, and defeats of people who are of African decent in numerous countries around the world. There are three major historical concepts that are the focus of this book. One is the spread of the Islamic religion. Another is the slave trade, and the last is the new trade in the nineteenth century and the coming of new ideas from Europe (legitimate commerce). However, Segu does not simply explain these circumstances externally, but rather with a re-enactment that tells a story of the state of affairs on a personal level, along with the political one. By doing this, the book actually unfolds many deceitful explanations for the decline of West African countries in the eighteenth and nineteenth century.…
