The Importance Of Water To Life On Earth A Look At The Unique Structur

The Importance of Water to Life on Earth a look at the unique structure and behavior of the water molecule by Steven Luscher, Student Water is the most important substance in our evolution and our daily lives. Without water, life as we know it would not have been possible. This essay will examine the water molecule in order to ascertain how it brought about Earth's thriving ecosystem and how important it is to us today. ============================== ______________________________ ============================== Each water molecule consists of one oxygen atom and two hydrogen atoms. The oxygen atom (or the apex of the water molecule) bears a slight electronegative charge while hydrogen possesses a more positive one1 (figure a). Because opposite charges attract, the water molecules are drawn together. When an oxygen atom is linked to a neighboring molecule's hydrogen atom, a bond called a hydrogen bond is formed2. In an ice crystal the hydrogen bonds govern the shape of the crystal so that the grid of molecules surrounds relatively large spaces (imagine figure b in three dimensions). In a liquid form, water has no such spaces; thus ice is less dense and will float on liquid water. If not for this, great bodies of water would freeze from the bottom up without the insulation of a top layer of ice and all life in the water would die. The water molecule is a very small one but because of its unique properties it behaves like a larger one. The bonds between water molecules are so strong that water resists changes in its state (Solid, liquid, gas); thus water has a higher melting point and a higher boiling point than another molecule of similar size. If water followed the example of other molecules its size it would have a boiling point of -75?C and a freezing point of -125?C4. This would mean that, on Earth, water would be a gas all of the time and life would not be possible. When heat is applied to solid water, some hydrogen bonds get so much kinetic energy that they break and the ice melts. Liquid water does not necessarily have all four hydrogen bonds present at all times but it must retain some of them5. For any object to penetrate water, it must be able to break the hydrogen bonds on the surface of the water. These bonds resist breaking thus forming a "skin" that allows small insects to walk on the surface of the water. Without the cohesiveness of water, those insects would not have survived. All plant life on Earth benefits from the ability of water to make a hydrogen bond with another substance of similar electronegative charge. Cellulose, the substance that makes up cell walls and paper products, is a hydrophilic substance ("water-loving")6. It interacts with water but, unlike other hydrophilic substances, it will not dissolve in it. Cellulose can form strong hydrogen bonds with water molecules7. This explains why a paper towel will "wick" water upwards when it comes in contact with it. Each water molecule will make a hydrogen bond w ith cellulose and pull another water molecule up from down below and so on. Without this feature (capillary action8), plants would find it more difficult to transport water up their stems to the leaves in order to make food through photosynthesis. Water has a very high heat capacity. Most of the heat introduced to water is used not to set water molecules in motion (giving them kinetic energy and causing their temperature to rise), but to move hydrogen atoms around between neighboring oxygen atoms9. If all of this heat was used solely to warm the water, living cells would boil in their own heat. Every action in a living cell releases some heat. If the heat was not dissipated by the water, all living things would cook themselves. In order for water to evaporate from the surface of liquid water, a certain amount of energy must be expended to break its hydrogen bonds. Because these hydrogen bonds are so strong, water requires a lot of heat to boil (100?C). When water vaporizes, it takes along all of the heat energy required to break its bonds thus having a powerful cooling effect on the

Ultimate and Penultimate

Ultimate and Penultimate Ultimate and Penultimate Ultimate and Penultimate By Maeve Maddox A DWT reader noticed this example of the use of penultimate as if it meant ultimate or best: a commentator at a tv broadcast of a national dog show commented on a particular dog (a close contender for best in show) being the penultimate dog of its breed group. Penultimate means â€Å"next to last.† The only way the dog referred to could be the â€Å"penultimate dog of its breed group† would be if it were one of two. Even then, the speaker would have to have some way of knowing which dog would be the last to die. Here are two more examples of writers using penultimate as if it meant ultimate: And since it is, after all, the penultimate in mens formal wear, screwing up the tux is also the penultimate faux pas. Ezine article With many benefits available to us in regards to protein, we should consider whey protein isolate as the penultimate source of protein. nutrition blog That the writer of the second example believes penultimate means something like â€Å"the most important† is further illustrated in the article I’m quoting from: â€Å"Whey is perhaps the healthiest form of protein that is available to our bodies.† (Yes, â€Å"in regards† is nonstandard.) I suspect that the extra syllable in penultimate leads some speakers to believe it must mean â€Å"more than ultimate,† the way the prefixes super- and extra- elevate the base words in superman and extraordinary. It doesn’t help that various manufacturers use the word penultimate to name their games, applications, and other products. Ultimate, from Latin ultimus, â€Å"last, final,† means â€Å"lying beyond all others.† The Roman poet Virgil coined the expression â€Å"Ultima Thule† to mean a far-off land or an unattainable goal. Medieval mapmakers applied the term to unexplored northern lands that lay beyond the borders of the world they knew. The prefix pene- means â€Å"nearly, almost, all but.† It occurs in a few obsolete English words, like pene-lake, â€Å"an expanse of water almost surrounded by land.† Like pene-, the pen- in penultimate is from Latin paene, â€Å"almost.† A peninsula is â€Å"almost an island.† The penultimate event or item in a series is â€Å"almost the last.

Structure and Framework of the Federal Courts Research Paper

Structure and Framework of the Federal Courts - Research Paper Example It is also out of the recognition that the constitution has for the broad nature of legal enforcement and the need to ensure that administration of justice and the enforcement of rule of law goes to the grassroots that there exists different parts and ranks of the court system, which is specifically assigned to interpret the constitution. This paper shall therefore visit the court system as the major framework that embodies the legal system and bring out the structure and role of the federal courts. Purpose and Function of the Topic One key aspect of the legal system in the United States and most other democratic states like United Kingdom and France is the court and the structure of it. In the United States, there is what is known as the Federal Court system, which has been vested with the power of interpretation of the law at the local level2. In essence therefore, the present topic, which is stated as â€Å"the structure and framework of the federal courts† seeks to achieve three major functions and purposes. The first purpose and function of the topic is to aid in the categorization of the federal court system. From a Congress viewpoint, the Supreme Court is the highest court in the land3. This Supreme court is overseen by a Chief Justice and eight other associate justices. But even within the Supreme Court, there are two constitutes of courts, which are the Appellate Court and Trail Courts. These bring the categorization down to smaller courts, which are made up of District Courts and Circuit Courts. In order to ensure that there is not at any point in time overburden on the courts in the jurisdiction of justice, there are as many minor courts as possible, all of whom have been assigned special duties, cases and roles to oversee and hear. Some of these include bankruptcy courts, magistrate courts, the U.S. Court of Claims, the U.S. Court of Veterans' Appeals, the U.S. Court of Military Appeals, the U.S. Tax Court, and the U.S. Court of International Trade. The second purpose and function of the topic is to clearly outline what the differences between a State Court and a Federal Court are. This is an important purpose to achieve with the topic because in a bid to educating the ordinary citizen of the legal system, it is very important for the citizen to have an idea of where to turn to in the event of different cases of legal concern. To this end, it would be said that unlike Federal Courts, most State Courts have very limited jurisdictions. From a legal perspective, this means that State Courts do not have as much power to trail wider range of cases as Federal Courts do4. Because of this, most judges in State Courts are appointed or elected only over a specified time frame and not for life as it is with Federal Courts. Some of the cases that a typical State Court would trail is reflective in the name of the court. Examples are probate court, family court, traffic court, municipal court, small claims court and juvenile court. F inally, this topic seeks to expatiate on the effectiveness of the sovereignty of the various levels of the Federal Court in the legal system and structure of the country. Indeed, one of the main principles on which the legal system works is the principle of independence. This means that every court must be given maximum room to operate without any form of interference from

Should the Stakeholders Investing in the Companys Assets Research Paper

Should the Stakeholders Investing in the Companys Assets - Research Paper Example The research includes a literature review to make the topic understandable. Red Bull should keep on investing in the formula one Championship for next year. Currently, Red Bull is one of the top Formula One racing tracks around the world. The Formula One circuit sports reporters regularly announce the standings and winning cars of each Formula One racing event. The sports writers’ informed the general public about the painstaking and scrutinizing victory of the Red Bull Formula One racing team to all racing and other sports fans in Sweden, in all Formula One race track, television, radio, and newspaper sports news. Red Bull is a beverage company that is strategically located in Sweden. As of 2007 alone, Red Bull sells 3.5 billion cans and bottles of its Red Bull products because the average Red Bull customer is not price conscious (Grisen, 2010). The Red Bull beverage company’s continued investment of next year’s Formula One events is part of the necessary promot ional aspect of the company’s overall marketing strategy. Simon Vigar reiterated (2008) just like in the prior years, the red bull name on one of the formula one race cars speeding past other competing cars often brings cheers, sadness, fear, and awe to the audiences watching the games. The Red Bull Formula One car is seen by thousands of fans visiting many Formula One grand prix circuits located around the world. During the live telecast and the news reports of the Formula One races, the Red bull name is seen by thousands of race track fans. Because of the sport news reports, the Red bull name will have free advertising in all the televisions, radio stations, and newspapers around the world. Thus, the cost of investing in the formula one circuit can be easily recuperated through the free news items found in the sports sections of the news papers, radio and television media around the world (Abele 2008). Business Question What strategies for developing a fast food chain? Aim – to identify the perception of product brand among the current and prospective clients Objectives: – to pinpoint the product brand store image held by this consumer group 1.To examine if there are different perceptions of product brand among the diverse age groups among the customers. 2. To determine which type of store brand is popular among the consumers. 3. To determine the competitors’ products and services with the aim of increase client base. Literature Review The marketing environment focuses on several theories. According to Hilton (2007), the SWOT analysis theory states that the company uses both internal and external resources in its decision making tools. According to the Managerial Accounting Studies, the theory states that the company must gather enough of its strengths to outsmart the competitors in terms of client generation and revenue increase. The theory states that the company should resolve all its weaknesses in order to have a successful bu siness or person endeavor. The company exerts all efforts to profit from its opportunities (Kumar, 2003). In addition, the company musters all its resources to hurdle all threats that come in the way of the way of the company’s achieving its aims and objectives. The marketing theory focuses on the four strategies. The company should focus on selling quality products and services (Czinkota, 2007). Product. Bucholz (2006) theorized that the company must implement some marketing changes to increase the clients’ demand for its products. The company must add additional shoe styles. The new shoe styles are based on the latest market segment trends. The company must increase the production of its ladies’

Prostitution - Analysis of Positivism and Classicism within Assignment

Prostitution - Analysis of Positivism and Classicism within Criminology via the Lens of Article - Assignment Example A discussion and analysis of the principle tenets of both positivism and classicism with regards to criminology will be engaged with.   Although it is not the purpose of this analysis to state that one approach is better than the other, the underlying goal is merely to state which one is the most effective in helping the reader to come to an appreciation of the causal and motivating factors that might have driven the individual to commit crime the first place. As a means of briefly describing the article to the reader prior seeking to define in terms of either positivism or classicism, the following serve as something of a brief summary. The article details the results of the plea bargain that was entered into by Ms Alexis Wright. Rather than facing a jury trial with over the charges, Ms Wright instead opted for a plea bargain that would see her serve 10 months in jail and pay a fine of just less than $60,000. Investigators case, the article reveals, had been gathering information upon Miss Wright as well as others involved, including client, for the space of nearly 2  ½ years. As with most high profile prostitution stings, Ms Wright’s enterprise made headline news in one of the nation’s most prominent newspapers due to two main factors (Seelye 1). The first of these is with regards to the high profile nature of her client list; referenced in the article is merely mayors, ministers, and high school coaches. The second deter minant that makes this high profile news is the fact that the actual place of prostitution served as both a Zumba studio and was located a mere stone’s throw from the vacation home of former Pres. George Bush. One of the hallmarks of the positivist’s school of thought with relation to criminology is the underlying belief that the individual/criminal is not always spurred on crime based solely upon free will. Rather, precipitating factors such as economic hardship, developmental impairment, or an otherwise incomplete worldview and/or understanding can just as easily lead an individual to commit a crime as can free will.

Can you guys hear me in the back?"   He gurgled in his natural grotesque voice. With the acknowledgment of the audience, he sipped the glass of ice water which stood on the podium and cleared his throat.   "Ladies and Gentlemen, I am here to inform you of a discovery that my team of genetic scientist and I have discovered."   The more he said the more I wanted to hear. I wanted to shout to make him blurt it out, but it was impossible to speed him up, attention was the reason why he became a scientist.   He didn't care about the effects of his discoveries, as long as he packed the expo center the next weekend.  Ã‚   "The quest toward perfection is finally over.   Your unborn children now have the opportunity to be everything you ever wanted them to be!"   A large blue vein slowly became visible through his cherry red forehead.
