Microbes And The Environment - 697 Words

Microbes And The Environment When you pick up a handful of soil from outside you are not only picking up soil you are picking up a handful of microbes. In that one handful there are many different varieties of living microbes, they range from algae, fungi, bacteria and many more. â€Å"A single teaspoon of that soil contains over 1,000,000,000 bacteria, about 120,000 fungi and 25,000 algae.†(Microbe World) They are found everywhere that you can think of on Earth, this includes the ground, air, plants and animals. Microbes are one of the oldest living things on Earth they have been around for billion of years and continue to live here under any conditions because they are constantly adapting to the environment that they live in. â€Å"These environments range from the boiling waters of hot springs in Yellowstone National Park to the freezing temperatures of Antarctica.† (Microbe World) The microbes that exist in our world are not all bad they have many very helpful traits that can be observed every day .Microbes just like bacteria and fungi break down complex pollutants into simpler substances to gain energy and nutrients by the process called biodegradation. â€Å"What biodegradation means is the chemical dissolution of materials by bacteria or other biological means. Although often conflated, biodegradable is distinct in meaning from compostable.† (Biodegradation.) Microbes are found naturally in the world and they are also used by humans for important reasons.

Essay about The Adventures of Huckleberry Finn Should NOT...

Many books around the world have been banned because they are offensive. One example is Mark Twain’s The Adventures of Huckleberry Finn, a novel about the journey of a thirteen-year-old boy named Huck, who fabricates his own death to run away with an escaped slave named Jim. The two voyage in a raft along the Mississippi River to gain their individual freedom. In addition, Huck gains a new understanding about humanity. Huck Finn has been creating great controversy on both sides of the argument: to ban or to keep in the school curriculum. Currently â€Å"much debate has surrounded Mark Twain’s Huck Finn since its publication in 1885, but none has been more pervasive, explosive, and divisive than that surrounding the issue on race†Ã¢â‚¬ ¦show more content†¦Negroes do not like it in any book or play whatsoever, be the book or play ever so sympathetic in its treatment of the basic problems of the race. Even [if] the book or play is written by a Negro, they stil l [would] not like it† (Henry). In addition, John Wallace believes that the word â€Å"nigger† is so offensive that he rewrote the novel without the word â€Å"nigger.† Not only did Twain overuse the word â€Å"nigger† throughout the book, he additionally portrays blacks badly through negative and insulting stereotypes. Student Doron Flake discusses stereotypes that African Americans have â€Å"chained† to them at all times when he says, â€Å"Blacks are murderers, the rapists the gang-bangers, where everything that is negative is [sic] society, why do I have to go to school and be Jim too? Because whenever I read about the slave who is gullible and stupid, that [stereotype] becomes a reflection of me, too† (qtd. in Chadwick-Joshua xi). Doron does not want his fellow classmates to judge him based on how Twain describes and displays African Americans. Twain portrays the dehumanization of blacks throughout his novel. An example of Twains dehumanizing attitude towards African Americans occurs when Huck and Aunt Sally discuss the steamboat incident that causes an explosion: Now I struck an idea, and fetched it out: â€Å"It warnâ €™t the grounding -- That didn’t keep us back but a little.

The widespread belief that dopamine regulates pleasure could go down in history with the latest research results on the role of this neurotransmitter. Researchers have proved that it regulates motivation, causing individuals to initiate and persevere to obtain something either positive or negative. The neuroscience journal Neuron publishes an article by researchers at the Universitat Jaume I of Castellon that reviews the prevailing theory on dopamine and poses a major paradigm shift with applications in diseases related to lack of motivation and mental fatigue and depression, Parkinson’s, multiple sclerosis, fibromyalgia, etc. We will write a custom essay sample on Effects of computer games to students or any similar topic only for you Order Now   and diseases where there is excessive motivation and persistence as in the case of addictions. â€Å"It was believed that dopamine regulated pleasure and reward and that we release it when we obtain something that satisfies us, but in fact the latest scientific evidence shows that this neurotransmitter acts before that, it actually encourages us to act. In other words, dopamine is released in order to achieve something good or to avoid something evil,† explains Merce Correa. Studies had shown that dopamine is released by pleasurable sensations but also by stress, pain or loss. These research results however had been skewed to only highlight the positive influence, according to Correa. The new article is a review of the paradigm based on the data from several investigations, including those conducted over the past two decades by the Castellon group in collaboration with the John Salamone of the University of Connecticut (USA), on the role of dopamine in the motivated behaviour in animals. The level of dopamine depends on individuals, so some people are more persistent than others to achieve a goal. â€Å"Dopamine leads to maintain the level of activity to achieve what is intended. This in principle is positive, however, it will always depend on the stimuli that are sought: whether the goal is to be a good student or to abuse of drugs† says Correa. High levels of dopamine could also explain the behaviour of the so-called sensation seekers as they are more motivated to act. Application for depression and addiction To know the neurobiological parameters that make people be motivated by something is important to many areas such as work, education or health. Dopamine is now seen as a core neurotransmitter to address symptoms such as the lack of energy that occurs in diseases such as depression. â€Å"Depressed people do not feel like doing anything and that’s because of low dopamine levels,† explains Correa. Lack of energy and motivation is also related to other syndromes with mental fatigue such as Parkinson’s, multiple sclerosis or fibromyalgia, among others. In the opposite case, dopamine may be involved in addictive behaviour problems, leading to an attitude of compulsive perseverance. In this sense, Correa indicates that dopamine antagonists which have been applied so far in addiction problems probably have not worked because of inadequate treatments based on a misunderstanding of the function of dopamine (http://www. sciencedaily. com/releases/2013/01/130110094415. htm) The effect of a dopamine agonist on dysarthric speech production: a case study. Abstract The effect of Permax (pergolide mesylate), a dopamine agonist, was assessed in an individual with traumatic brain injury. The participant evidenced symptoms of hypokinetic dysarthria. His performance on and off Permax was evaluated in a BABA design. Measures were obtained across physiological systems. There were few differences in the on and off conditions. In the on condition, he evidenced an abnormally large velopharyngeal orifice area, dysfluencies in stimulus sentences, and less precise articulation. However, listeners perceived him to be more animated in the on condition. In addition, he reported better performance in the on condition. The study highlights potential discrepancies among participant report, listener perception, and objective measures. Learning outcomes: As a result of this activity, the participant will be able (1) to recognize the effect of dopamine agonists as an adjunct to other pharmacological interventions and (2) to determine potential discrepancies among participant report, listener perception and objective physiological and acoustic measures.

Hero and Leander free essay sample

This paper distinguishes between the two voices in Marlowes epic poem the Hero and Leander. This paper explores the similarities and differences between the two separate voices, one being the narrator and the other the poet himself, in the context of Marlowes epic poem Hero and Leander. For the reader of Hero and Leander, another dilemma with the narrator and Marlowe the poet arises when we ask the reason for Marlowes desire to tell his tale through the eyes and voice of an unidentified narrator apart from himself. The initial reaction of an observant reader would be that the narrator is quite inappropriate for this poem. Hero and Leander then represents Marlowes ultimate attempt at human comedy via a speaker who represents the poets own image of human nature. In Christopher Marlowes narrative poem Hero and Leander, a major obstacle confronts the reader in the form of attempting to separate the narrative voice of the poet Marlowe from that which W.

Godshalk calls the sensibility of a dramatized narrator. . . who stands between us and the lovers (307). David Farkas, in his Problems of Interpretation in Marlowes Hero and Leander,` points out that he hears `two voices in the narrative: the genuine Marlovian voice and the hidden narrators (Knoll 129). In light of these observations, the question arises as to the means of distinguishing between the dual voices present in the poem. Godshalk asks Is it Marlowe or the narrator who is so taken with Leanders physical beauty and with Heros pretended innocence even as she coquettishly leads him on? (308). Thus, Hero and Leander, in regards to the poet/narrator question, builds its own mysteries and demands a variety of responses which are compounded by the fact that we see (the characters) through the eyes of Marlowe, the poet, and through those of an intrusive narrator (Levin 140).
