CELL ANATOMY The cell theory proposes that all organisms are composed of cells and hence cells are the fundamental unit of all life. Human cells are typically 5 to 100 Â µm in size and therefore cannot be viewed without the use of a microscope [1]. They are, however, extremely organized, being responsible for the biochemical processes that are essential to sustain the life of an organism. Cells are compartmentalised in order to increase the efficiency of the biochemical processes as well as protect the genetic information. Such compartments are called organelles which are each bound by their own membrane and each serve a specialised function. Humans are made up of trillions of

An Analysis Of Edgar Allan Poe s `` The Raven, And The...

The use of characters in Edgar Allan Poe’s short stories like â€Å"The Raven,† and the Pit and the Pendulum,† show psychological elements, and make the stories more mind boggling and delusional. Authors choose a certain technique on how they write their stories based on how they want the audience to feel and think when they read it, and also based off of their personal backgrounds. Edgar Allan Poe’s stories are described as â€Å"disturbing† with disturbed characters. His stories are meant to bring chills down the spine. Most of them are based on death, and the darkness it brings to the mind and how it affects your mental state. There is not life without death, and Poe really exaggerates this in his stories. Edgar Allan Poe was born on January 19, 1809. He was born in Boston, and his parents were both actors, and died before he made it to the young age of three. He was then raised by John and Frances Allan as foster child living in Richmond, Virginia. Poe was sent to the most prestigious boarding schools by his Uncle John and excelled in academics while attending. He was later sent to the University of Virginia. Poe was not at the university for long before he was forced to leave because his uncle refused to pay debt he had collected by the gambling problem he possessed. After being kicked out of the University, Poe went back to Richmond, where his relationship with his uncle would soon fade. He moved to Boston in the year of 1827, and enlisted in the United StatesShow MoreRelated Juxtaposing the Most Similar Contradiction in Edgar Allan Poes Work2077 Words   |  9 PagesThroughout all of Edgar Allan Poes works are common ideas that oppose each such as madness versus sanity, r eality versus the imagined reality and life versus death.

Celiac Disease Unit 4: Assign 2- Disorders Affecting the Immune System April 9, 2013 Celiac disease is an autoimmune disorder. It affects the small intestine in the person’s body. It can affect people who have been linked genetically or pre-disposed from infancy to adulthood (www. We will write a custom essay sample on Celiac Disease Paper or any similar topic only for you Order Now mayoclinic. com). This disease can be asymptomatic. Which means that the person can be a carrier of this disease and pass it on to their children. The carrier would not have any symptoms of this disease or even know they are a carrier. Celiac disease can affect 1 in 105 people in the United States (www. webmd. com). Celiac disease is caused by a reaction to gliadin, or a gluten protein. The gluten protein is found in wheat, barley, rye, and oats. When the person affected with this disease is exposed or ingests the gluten protein, their immune system has an inflammatory reaction in the small bowel. The inflammatory reaction can be an acute or chronic response within the bowel tissue. The inflammation in the small bowel blocks the person’s ability to absorb vital nutrients from their food (www. ebmd. com). Signs and symptoms of Celiac disease can range from mild to severe. Diarrhea is the most common symptom of this disease. Abdominal pain, bloating, cramping, and distention of the abdominal wall from gas are also other signs/symptoms of Celiac disease. The blocking or malabsorptio of nutrients such as Calcium and Vitamin D can lead to weight loss, fatigue, and anemia. The person can then get mouth ulcerations as well, and become lactose intolerant. As the disease continues to progress it can cause more damage and it puts the person at risk for small intestine cancer (adenocarcinoma) or Lymphoma. If left untreated Celiac disease can also lead to more complications within the affected person. Some of the complications they would experience are, ulcerations and strictures in the bowel (www. webmd. com). The only affective treatment for Celiac disease is a lifelong goal of diet change. Once diagnosis has been confirmed gluten must be completely removed from the person’s diet. Certain diets that are gluten free will need to be followed to prevent inflammation. Depending on the extent of the damage done, or the stage of progression there may need to be more strict changes to follow. There are websites and support groups to help people become educated with the steps necessary to prevent further flare ups from this condition. The first step to becoming aware of this disease is to be seen by your physician if you are having any of the above signs and symptoms (www. csaceliacs. com). www. mayoclinic. com,2013. www. webmd. com,2013.

Greece free essay sample

She looked up at me with her large, sad eyes; her pain unbearably obvious. I watched her as she glided silently around her small, blue pool, surrounded by people she neither knew nor understood. The chatter turned to a dull roar as I examined her features more closely. The top left corner of her green and yellow shell was missing, and her flippers were mangled with cuts and scars. I slowly walked over to a second pool. The poor creature contained in this pool had suffered a severe head wound. A third creature displayed a large crack down the middle of his pentagon patterned shell; a fourth an amputated flipper, and yet another was missing an eye. I couldn’t help but think that these unfortunate creatures looked as though they were war heroes that had been wounded in battle; but they weren’t. They were just a group of innocent sea turtles that had been injured by careless humans. We will write a custom essay sample on Greece or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page I glanced at the beach, watching the aquamarine waves overlap each other, crashing onto the rock-cluttered beach, lapping up the sand as they went back in. The sun was setting as an array of oranges, pinks, and golds spilled across the sky. Our second day in Greece was coming to a close, and we still had a lot of work ahead of us. My friend Liz turned towards me. â€Å"This is horrible. How can people do this?† â€Å"Because people don’t realize the damage they cause to the environment until after something has been destroyed,† I replied. Earlier that day, our group of 40 high school students had learned that these endangered sea turtles were being wounded and killed all the time because of pollution, litter, and careless boaters and fishermen. We were taught how to teach people back home ways to lessen the deaths and injuries of this species and how to encourage others to conserve our ocean life and the environment in general. I had always been conscious of the damage our environment was suffering, and I had always been concerned with environmental conservation, but I had never truly been given the opportunity to see the devastating effects of environmental destruction up close until I observed those turtles. Seeing a picture or a movie of these animals cannot truly capture their pain and the melancholic expression on their faces. Now that I have personally seen the harm caused by pollution and carelessness, I try to encourage my peers to change their daily habits to benefit the environment by recycling, conserving water and energy, or donating time and money to help save endangered animals, such as the sea turtles. I stress to them that we need to start saving our environment now before it’s too late; we must fight for those creatures that cannot fight for themselves. We only have one world to live in and one chance to save it. Now I will always be that person who’s running after that ice c ream wrapper flailing crazily in the wind just because I hate the thought of even one piece of litter on the ground.
