Carbohydrates (785 words) Essay Example For Students

Carbohydrates (785 words) Essay CarbohydratesCarbohydrates are present in sugars, starch, acids, and in many other nutrientsthat consist elements of carbon, hydrogen, and oxygen. Having a ratio of 1: 2: 1or written as CH20. A monosaccharide meaning monomer of sugar is asimple carbohydrate. Containing backbone of five carbon atoms thatare present in ribose and deoxyribose, components of RNA and DNA. Glucose a sixcarbon atom that is common cellulose, starch, and glycogen are classified aspolysaccharide, Known as a complex carbohydrate, with straight orbranched chains of many sugar monomers. These categories of carbohydrates aretested in two laboratory experiments. It will allow us (my partner and I) todetect the presence of sugar or starch. The first test, using two differentsolutions to expose the presence of sugar or starch by color alteration. Ihypothesize that both samples of the experiment will result differently in orderto pursue the next test. The second test consists of 9 food items, identifyingthe appearance of sugar or starch. I guess in identifying 75% out of the 9 itemsright. Conducting both experiments will test my hypotheses either right orwrong. The first experiment on simple and complex carbohydrates,several tools and liquids were obtained: two test tubes, spot plate, test tubeholder, benedicts reagent, lugols iodine, 10% karo syrup solution, 1% starchsolution. In a test tube (holding it with a test tube holder,) my partner fills1 cm from the bottom of 10% karo syrup solution. With the benedicts reagent Igently add four drops, then quickly placed the tube in 98 degrees of boilingwater, at 3:17p.m. While waiting for 3 minutes, we noticed that before placingthe tube in the boiling water, the benedict reagent in the 10% karo syrup wasblue. After heating, we observed at 3:20 p.m. that the benedict solutionactivated and turned yellow. Which meant that sugar (simple carbohydrate) waspresent in the karo syrup. A different procedure was conducted to test starch. Using a spot plate, 1% of starch (about 4 drops) was placed into the well spot. Then two drops of lugols iodine was added. It generated a dark purple colorwith immediate contact with the iodine. The results for this experiment meantthat lugols iodine would test purple, positive for complex carbohydrate andyellow for simple carbohydrates. Both samples of the experiment resulteddifferently agreeing with my hypotheses. With the color alteration of benedictreagent and lugols iodine, my partner and I was ready to test sugar andstarch on the 9 food items. Know will test the 9 items, to state weather starchor sugar is present. I made a prediction that 75% of the items would beidentified correctly. The experiment consist of: apple juice, potato juice, saltwater, baking powder solution, baking soda solution, ozorka flavored water,powdered sugar solution, clearly Canadian flavored water, vinegar, benedictsreagent, lugols iodine, wax pencil, and 18 test tubes. My partner numberedthe test tubes, having two sets from 1 through 9. He filled one set while Ifilled the other, bo th with food solution about, 1 cm from the bottom of thetest tubes. After filling the tubes, we placed 5 drops of benedicts reagent onone set, then placing them in boiling water at about 98 degrees for five minutes(3:40 p.m.). Within the five minutes, I placed three drops of lugols iodineon the second set (3:42 p.m.). We shook the tubes, then resting them for 3minutes. At 3:45 p.m., my partner took out the benedict set, and we started torecord our result as we also recorded the lugols iodine. We both had amazingoutputs; I resulted on having 6 items accurately correct out of the 9. Bakingsoda solution and vinegar failed both the benedict and lugols iodine fluids,appearing negative results for sugar and starch. I predicted that Salt waterwould show starch therefore it appeared negative. Vinegar has an acidicelements, that are naturally fermented by which bacterium (prokaryotic) gothrough, an anaerobic cycle. Baking soda is a sodium bicarbonate, it isnaturally occurring in the form of an ore called torna. It releases more OH ,which it has a pH above 7. Salt is a sodium chloride, also with a pH numbergreater than 7. For these reasons, my estimation was not accurate. Some of theitems were organic fluids, processed powders, and flavored water, which containeither starches or/and sugars. The categories of carbohydrates were tested intwo laboratory experiments. It allowed my partner and I to detect the presenceof sugar and starch with indicators, (benedicts reagent and lugolsiodine). The test results indicated that certain Items were composed of carbon,containing substances that include lipids, proteins, and nucleic acids. Otheritems were composed of non- carbon such as water, calcium, sodium, magnesium,and other elements. For future experiments, this lab will help explain the causeand effect of any living structure.

The Performance free essay sample

Step One: Prepare. The strong yet whimsical force of a simple port de bras, or the power with which a dancer delivers an entire performance, begins with the dedication of the dancer to commit countless hours practicing, learning, observing, trying, failing, succeeding, and preparing. My parents entered me in a dance academy as early as age three, where I spent every Saturday afternoon learning the first five positions and how to do a grand jete. By the age of around 7, I grew an overwhelming passion for dance. Saturday afternoon classes turned into Thursday/Friday/Saturday classes, and soon I was at a competitive studio developing my technique nearly every day of the week. I struggled for some time with feeling I wasn’t a good enough dancer. The competitive atmosphere lead me to have moments of low self-esteem and doubt. In class I wasn’t the girl with the perfect turnout nor could I do ten continuous pirouettes. We will write a custom essay sample on The Performance or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page However, for every performance my class did, I found myself front and center. I later discovered that what my instructor saw in me as a dancer was something much more forceful than mere technique. Although I had ‘a nice pointe, and legs which extended my height by five miles’, I also delivered every dance piece with true desire and inspiration which bled through every arabesque and battement. Step Two: Warm Up. 2008 was a bad year. My parents dominated the High School process. They came to a decision, and their first choice school was my last. That year, I struggled with rebellion. I was angry that such a significant part of my life had been decided for me. Dance became backseat to school for my parents, once my grades began to show. I lost motivation and found myself surrounded with people who had lost theirs as well. I was naive and felt as though my world had ended. I felt no need to try, and as time passed I began to lose everything. My parents took me out of dance. The passion which once fueled me to at least endure the six hour school day, looking forward to the five hour dance day afterwards, was gone. My grades were dirt, and so did become my reputation. I was in a hole which only made itself deeper with every report card. I embraced every negative situation. One extremely rainy May afternoon, I had to walk home from school. I took the shortcut passing downtown p rovidence, my favorite area. I got a little lost, but despite the downpour, I didn’t mind spending some extra time in the scenic area. Fifteen minutes later I was still walking, but slowed my pace as I approached PPAC (Providence Performing Arts Center). I saw on the window an announcement for an upcoming event. â€Å"The Alvin Ailey American Dance Theater† was bringing its dancers to this stage to perform. I literally felt warmth from the passion I had lost, returning into my shivering body. When I returned home, I sat in my room for hours with my re-found inspiration, and became more and more absorbed with every minute spent. In that time I came to a realization. Dance is my warm up for life. Instead of having rebelled, I should have faced every negative instance I had been dealing with in high school with the grace and strength of the dancer that I was. I knew what it was to sacrifice time, to endure sweat and tears, to dedicate countless amounts of effort to reach a desired goal. The morals I learned in the studio, behind ballet bars and in front of mirrors, were the same I had to apply to reach my maximum potential in school and in life. Step Three: Approach the stage with confidence and grace. That year I finally became balanced. I continued to grow as a dancer, and strengthened my role as a student. I presented myself with assurance and used difficult situations as warm-ups for things that still lay ahead. I watched my accomplishments stack up and account for the opportunities I had lost during my lower times. I stopped regretting my period of self-destruction, because those moments are what lead me to so strongly implement the art of dance into my daily life. I now have a vision for the future. Every effort I make is working towards my prize goal, acceptance to Fordham University/Alvin Ailey BFA program. Step four: Deliver a unique, unforgettable and heartfelt performance which inspires the audience to connect with their inner artist. Having to persevere my way through a great fall has built me into a strong, dedicated dancer and student. The details of my life provide a lesson that is my own, and have given me a place from which to grasp wisdom. Seeing my life from a negative place gave me the understanding perspective to share with others the importance of finding a source of motivation and passion in their lives.

Using the Scoring Rubric and Sample Student Answers As Your Scoring Guideline

Using the Scoring Rubric and Sample Student Answers As Your Scoring GuidelineAs a new teacher, the first thing you will notice when it comes to using the scoring rubric and sample student answers as your scoring guideline is that not all questions will go the same way.

Plesiadapis Facts

Plesiadapis Facts Name: Plesiadapis (Greek for almost Adapis); pronounced PLESS-ee-ah-DAP-iss Habitat: Woodlands of North America and Eurasia Historical Period: Late Paleocene (60-55 million years ago) Size and Weight: About two feet long and 5 pounds Diet: Fruits and seeds Distinguishing Characteristics: Lemur-like body; rodent-like head; gnawing teeth About Plesiadapis One of the earliest prehistoric primates yet discovered, Plesiadapis lived during the Paleocene epoch, a mere five million years or so after the dinosaurs went extinct- which does much to explain its rather small size (Paleocene mammals had yet to attain the large sizes typical of the mammalian megafauna of the later Cenozoic Era). The lemur-like Plesiadapis looked nothing like a modern human, or even the later monkeys from which humans evolved; rather, this small mammal was notable for the shape and arrangement of its teeth, which were already semi-suited to an omnivorous diet. Over tens of millions of years, evolution would send the descendants of Plesiadapis down from the trees and onto the open plains, where they would opportunistically eat anything that crawled, hopped, or slithered their way, at the same time evolving ever-larger brains. It took a surprisingly long time for paleontologists to make sense of Plesiadapis. This mammal was discovered in France in 1877, only 15 years after Charles Darwin published his treatise on evolution, On the Origin of Species, and at a time when the idea of humans evolving from monkeys and apes was extremely controversial. Its name, Greek for almost Adapis, references another fossil primate discovered about 50 years earlier. We can now infer from the fossil evidence that the ancestors of Plesiadapis lived in North America, possibly coexisting with dinosaurs, and then gradually crossed over to western Europe by way of Greenland.

Imminent, Immanent, and Eminent

Imminent, Immanent, and Eminent Imminent, Immanent, and Eminent Imminent, Immanent, and Eminent By Maeve Maddox Judaye Streett has asked for a tip on the similarly sounding words imminent, immanent, and eminent.

(Oral Presentation script) Ethical problems in international marketing Essay

(Oral Presentation script) Ethical problems in international marketing - Essay Example uch as, racial discrimination, corporate social responsibility, public awareness of risks associated with product use, keeping high prices for citizens of developing countries, and respecting the political and cultural environments of other countries. After describing the problems and their effects on a company’s image, the researcher provides some effective mechanisms to deal with those international marketing issues. Through discussing these problems, this research highlights the importance of considering ethics while doing international marketing. In the present world, ethical marketing is the key to success for a company in the international world. Those days have gone when companies needed to consider the business laws, customers’ needs, and culture of only their host nations. Today, companies need to consider the cultural, political, and economic environment of all those countries where they plan to expand their businesses. Failing to consider any of the ethical marketing issues can result in destroying the image of the company among international customers. Marketing managers are responsible to draw their focus properly on each of the ethical marketing issues in order to achieve the desired set of goals. Therefore, in this paper, the researcher will focus the international marketing ethical issues and the ways to overcome those issues. If a company discriminates against any particular race while marketing the products in the international world, it can put an adverse impact on the image of the company. For example, if a company markets a color fairness cream in an African country by saying that White is the best, it would be against the ethics of marketing. Companies also need to make public aware of the risks associated with the products being marketed. For example, if a pharmaceutical company is marketing a new drug in other countries, it should make people aware of the side effects of the product, if any, in order to make them decide whether they

Sociological research-there is a relationship between social class and Essay

Sociological research-there is a relationship between social class and crime - Essay Example ade great strides in proving that social class has a direct correlation with crime due to the social controls of a capitalist government† (Jones, 2004). Social conflict theory focuses on why governments make and enforce rules of law and morality then why an individual violates the law. The primary goal of Social Conflict is to examine the relationship between the ruling class and the process by which deviance is defined and controlled in capitalist society. The government creates laws and rules to maintain the power and position for the power elite. Centering on a view of society in which the elite class uses the criminal justice system as a means of controlling threats to its status. Conflict theorists do not argue that the poor commit more crimes than the rich, but they are certainly arrested and punished more often. A natural frustration exists in society in which a high value is placed on being rich and attaining the American dream, but this dream is unattainable for the ma jority of the citizens. A deep hostility develops among the lower class toward a social order that they can not participate unless it’s by illegal means. Thus, the legal system is designed to guard the position of the upper class by any legal means necessary. â€Å"Conflict theorists seriously contradict the long-held presumption that the American system of law and justice is humane and fair to all citizens.† (Senna, 2003) It really is not a surprise to any of us that it is the poor and disadvantaged criminals who end up in the coils of the criminal justice system. But it would be a mistake to make accusations about the nature of crime by blaming those individuals who end up in our police cells, courtrooms and prisons. This does not mean that crime in the US or any other part of the world is committed by the poor and disadvantaged. Nor does it mean that disadvantage is the cause of most crime. â€Å"But some of the grossest victimizations are concentrated among the poorer members of
