Basic Chemistry for investigating living things

Which test tube represents the control? The one with water. C. Why? When protein molecules are present, Beirut Reagent reacts with the protein to form a purple color. Tube number one is the control tube because it is distilled water and has no protein; the tube has no color. C. Which test tube contained the most test substance? Amylase D. Other than the control, which test tube contained the least test substance? Hard to say because the other ones didn't have much of a color, so it didn't seem like there was much protein at all. E. Did the results agree with your initial hypothesis in every case? Yes F. Why or why to?Starches and sugars are helped by protein enzymes and Amylase is an enzyme. Good source of protein, so I thought Albumen would have protein Eggs are a foods, but the Beirut reagent isn't strong enough to pick up small amounts G. If the color change is not as you expected, what might be the reasons? Contamination H. Add another 5 drops of Beirut Reagent to each test tube and stir as before. Do your results change? I didn't notice any change Discussion A. What is the purpose of this exercise? To use color to detect if substances have protein since Beirut reagent would react with a protein to form a purple color B.Why is it important to clean droppers and equipment between chemical uses? To avoid cross contamination C. What other types of foods or substances contain high levels of protein? Meat or fingernails D. Suggest a situation where you might use the Beirut Reagent colorimetric test. It kidney disease E. What other types of analytical procedures detect the presence of proteins? The Lowry Method Exercise 2: Testing for the Presence of Starch in Cells A. What is the test substance? Starch B. Which test tube represents the control? Water C. Why? Water has no starch and it turned amber, so if your color was amber, you ad no starch D.Which test tube contained the most test substance? Potato starch Other than the control, which test tube contained the least test substance? Albumen and amylase E. Did the results agree with your initial hypothesis in each case, why or why not? Known to have starch, and they did. I didn't expect the proteins Yes, potatoes are to have starch sources, but they're not in every natural food source G. If the color change is not as you expected it to be, what might be the reasons? That items I did not think had starch, actually did have it. A. What is the purpose of this exercise?Iodine reacts with carbohydrates to form a dark blue color, so you would know if the substance had carbohydrates based on the color it turned. B. What other types of foods or substances contain high levels of starch? Wheat grain C. Suggest a situation where you might use the iodine colorimetric test. Testing for thyroid issues D. What other types of analytical procedures detect the presence of starch? Detect the presence of starch by using the chemical method A. What is the test substance? Sugar C. Why? There is no sugar in water , and it turned a light blue.Any test with that color old mean that there was no sugar C. Which test tube contained the most test substance? Glucose D. Besides the control, which test tube contained the least test substance? Potato starch D. Did the results agree with your initial hypothesis in every case? Yes E. Why or why not? The test specifically looks for glucose, so other carbohydrates and starches that don't have glucose, will not show sugar F. What are you conclusions about the results? Glucose will react with Benedicts reagent G. If the color change is not as expected, what might be the reasons? Contamination

Analysis Of Aint Any Makin It Sociology Essay

Analysis Of Aint Any Makin It Sociology Essay The essay is a critical analysis from a sociological point of view of the book ain’t No Making it, third edition by Jay McLeod and published in 2008. The author divided the book into three distinct parts; part one The Hallway Hangers and the Brothers as Teenagers, part two Eight Years Later; Low income, Low income and the last part Ain’t No makin’ It. Through the eyes of the two groups used by McLeod, the brothers (black minority boys) and the Hallways (white boys) we are able to clearly see what transpires in an American societal setting. The two groups lived and studied in the same conditions but each has varied expectations and aspiration, this is on the basis of their race. The Brothers viewed an open society as the way life should be lived and held the opinion that the difficulties they are going through is due to racism their ancestors underwent. For this reason, they try as much as possible to engage in socially acceptable manners. This group does have hi gh expectation as well as aspiration. On the other hand, the Hallways do not accept the same achievement ideology held by the Brothers. The individuals in this group have lost hope, do drugs, drop from school plus engaging in a myriad of other activities deemed illegal. From the author, the two groups did not get themselves out of poverty. The reason I bet is that there are numerous barriers in the society that blocked their quest of getting themselves out of poverty. It is worth noting that a number of other concepts from sociological point of view clearly emerge. These include social conflict, poverty, gender and racial inequality, males as role model, political power, defeatism, education and society/elites and generational mobility (McLeod 17). Social conflict From social conflict theory which argues that human beings as well as groups in a given society do at any given time have varied amount of both material and non material resources. For this reason, those deemed wealthy or rich and more powerful exploit the less privileged. Another theory that will be analyzed along the social conflict one is Bourdieu social reproductive theory which asserts that those kids born by working class parents will automatically end up finding better jobs. It is evident that the Brothers did acknowledge that the difficulties in life they are facing at present are nothing but as a result of the serious racial discrimination their fore fathers went through. A typical example of social conflict is in the field of education in the book. Those kids from lower class families are treated in a manner by the teachers that suggest they (students) are less competent. Thus they are placed in a lower track as they lack opportunities to develop their language. In this category, these students are only trained to later in life take blue color jobs while those from affluent families are trained to take white color jobs. Additionally, the two kinds of school, public and private provide us wi th a clear distinction between where kids from wealthy and poor background attend school (McLeod 287). On the same note, students from less privileged families are disadvantaged by their manners, the way they talk, dress and deemed not to be fit and valued in the education systems

Long-Term Orientation in Chinese Business Markets Literature review

Long-Term Orientation in Chinese Business Markets - Literature review Example According to the authors, guanxi behaviour consists of three elements: affect (emotions), reciprocal favour, face preserving. In Chinese culture, trust is an outcome of guanxi behaviour. The authors emphasise that in China, affection and business go together unlike the UK or USA. Affect denotes human feelings or emotional commitments that are central to intimate social bonding in several kinds of relationships such as between teachers and students, parents and children, or between close friends. In Chinese culture, the reciprocal favour stems from certain social behaviour evoking emotional responses and feeling by one of the group member to another. As such, reciprocity is a universal behaviour that can be traced even to animal kingdom. Similarly, the importance of face preserving for any Chinese in personal and professional life is tremendous. Face preserving behaviour plays a crucial role in constructing interpersonal relationships. It is important to note that in the Chinese cultu re, any disloyal person in the group is a faceless person. Society associates a great value when members of the group go to any extent to honour their obligations. Thus, it can be said that guanxi is a fulcrum of most activities in China that fall into the purview of political, economic and social order. However, to gain more clarity, researchers interviewed over a dozen sales managers in China and Hong Kong to find out how they view guanxi in the business world. ... As replied by the sales managers, guanxi is the first step of a salesperson to establish his or her intention to do the business; however, guanxi behaviour takes considerable time to develop to the point where unfamiliarity with the buyer ceases to exist. According to the sales managers interviewed, most Chinese firms respect guanxi style of relationships while doing any business transactions. That means the higher the salesperson interacts with a buyer, the greater the trust the buyer reposes in the salesperson. Surprisingly, business transactions are done on the basis of trust at personal level rather than at the organisational level. That is why many transactions with overseas firms are done on the basis of personal contacts. People are more loyal to their superiors rather than their organisation. A buying firm's trust on the salesperson is due to his or her expertise on the subject and ability to deliver. Similarly, the higher the status or position of the salesperson, the higher the trust the buying firm will repose on the selling firm. This is so because higher status of the salesperson signifies greater control on the firm's resources to fulfil agreed obligations. The researchers formulated various hypotheses to understand how a buying firm develops trust on the seller firm including the factors such as salesperson expertise and his or her status responsible for generating this trust. In the process to measure all the three elements of guanxi as mentioned above, the authors served the questionnaire to 250 respondents; however, only 51.2% respondents returned the questionnaire. Those who responded were in their current positions for last 4 years and in relationship with

Wind Turbines for Power Generation Research Paper

Wind Turbines for Power Generation - Research Paper Example For instance, there are activities that can be applied in setting up these structures, which include manufacturing of materials and transportation of these components to the sites. Furthermore, CO2 omissions occur in the process of turbines construction and other supporting infrastructure, maintenances and decommissioning of the site (Kubiszewski, Clevelan & Endres, 2010, 286). However, this is one of disadvantages associated with wind turbine for power generation; thus, there will be other disadvantages discussed in this paper. Opponents of wind power generation whether onshore or offshore claim that there increased requirements of construction and operation, which does not put into consideration other types of power generation (Firestone & Kempton, 2007, 1584). Therefore, there is need to considered requirement of installation energy in order to assess the suitability of wind power generation based on its cost-effectiveness in the process of developing it as a source of energy. In this case, the cost incurred in the process of setting up the infrastructures need for site installations is not comparable to the anticipated energy generation during the lifespan of these structures. On other hand, the time consumed to install and generate energy is long; hence it results to increased costs in manufacturing and construction of these infrastructures due reduced payback period (Blanco, 2009, 1372). In addition, there have been significant increases of costs in generating wind power for the last three years due to increased demand and high prices of raw materials. Setting up an offshore wind power generation site requires increased amount of capital cost due to the operations and management costs involved; in fact, they are twice the costs incurred in setting onshore sites (Firestone & Kempton, 2007, 1585). In this case, offshore sites involve increased costs incurred in the process of laying foundation, setting submarine transmission cables and installation faciliti es. Moreover, there are difficulties experienced in dealing adverse sea condition in the process of setting up an offshore site for wind power generation (Green & Vasilakos, 2011, 496). Apparently, this high capital cost requires the government to incur significant const in the process of financing this developing industry. Besides, this requires additional capital to integrate the operations of the plant with technology, thereby decreasing the economies of scale. There is a degree of uncertainty involved in generation of power using wind; hence, this increases problems caused by wind unavailability. In fact, this has created significant challenges, which are faced by transmission operators compare to traditional way of generating power (Strbac, Shakoor, Black, Pudjianto & Bopp, 2007, 1214). Furthermore, there are not chances of predicting and integrating wind availability with the national grid. However, these challenges are deal by incurring financial costs, though there are other disadvantages associated with underestimation of resilience offered by distribution of wind; thus resulting to under applied resources. There are other limitations associated with use of wind turbines for power generation, whereby it involves resources that are not available without uninterrupted supply, hence, it is irregular. In this case, this limitation is considered a critical factor bearing in mind that dealing with power generation output should be balanced with demand; in fact, this is due the fact that electricity for major energy supply cannot be stored efficiently. For instance, output is decreased by lowering the

In return, PepsiCo would benefit from Lipton’s reputation as a

Unit 4 complete Assignment Example | Topics and Well Written Essays - 750 words

Unit 4 complete - Assignment Example In the US, the federal courts have special jurisdiction (Neubauer & Meinhold, 2013). Subject-matter jurisdiction refers to a court’s responsibility over matters and concepts of a case (Neubauer & Meinhold, 2013). On the other hand, personal jurisdiction refers to a court’s power over the persons involved in a case. In crime, causation of harm must be confirmed. In addition, a convicted person must have been in the right mental state to certify the validity of case. In essence, the defendant person should be proven to have acted with malice aforethought (Gross, 2012). Besides, the court process should prove the defendant as having actually acted or unlawfully omitted an act. In certain cases, a prosecutor may refuse to prosecute a given criminal case. For instance, there could be inadmissible evidence. In addition, a backlog of cases may require postponement of a given case. When a certain party in a lawsuit has unguarded jurisdiction, several problems may arise. To begin with, such a person may direct the case to suit one’s interests rather than the interest of justice. In addition, such a person may make mistakes that jeopardize a lawsuit process since one faces limited questioning from other parties. Besides, laxity from the single party may lead towards incompetent rulings. The US court’s system possesses a hiercahy at the federal and the states’ level. The federal courts exist in every state, and they represent the judicial branch of the US Federal government (Neubauer & Meinhold, 2013). On the other hand, the state courts operate under the unique states’ constitutions and laws. The federal court system operates in terms of districts and circuits. The circuit courts are the state appellate courts, which report to the US Supreme Court. The state courts divide into trial courts, appellate courts, and highest state courts. The main purpose of US courts is to defend the individual freedoms and rights that every citizen holds.

Integration of the Individual in the Community and Home in Hawthornes Essay

Integration of the Individual in the Community and Home in Hawthornes Roger Malvins Burial and Andersons Mother - Essay Example There are still others who are at odds with the value system of their community and have chosen to be silent outsiders who may have only physical presence in the group. Yet, another type is the rebel who is at loggerheads with the values any systems of the community. Others have realized the futility of the existence of a community to which he or she belongs and may be out to reform it. The possibilities of the patterns of individual's integration to community are many and the study is targeted to examining the integrations of the individual in the community and home in Hawthorne's Roger Nathaniel Hawthorne's works are passionately taken up with moral problems of sin, punishment and atonement. His knowledge of the history of his own ancestors perhaps goaded him to explore these themes of guilt. The 17th century persecutions of the Quakers and the witchcraft trials of Salem troubled him. The insight of Hawthorne into the motivations of behavior and the guilt and anxiety in his characters are the legacy of the past sins to humanity. Hawthorne deliberately manipulated historical data and churned out the moral concerns behind them. The truth of human heart remains a mystery in his characters and his ambivalent approach to what is good and bad, is far ahead of his times. If Hawthorne was obsessed with ethical dilemmas in his works, Anderson Sherwood was concerned with mundane problems that affected the fortunes of the ordinary people. The machine age took away the human factor from work. This dehumanized the American work place in a way. Apart from that, it also threatened the very existence of the workers. In a world of competition many values were lost and in the ruthless drive for individual attainment human beings lost sight of the social and family dimension of their existence. Roger Malvil's Burial, when examined in the backdrop social dimension of man existing in a society reveals that concealment can cut off a person from the social communion with his community and family. Early Christian religious practices insisted on public penances for serious sins. Sin was not merely a matter between God and man; it has a social dimension and hidden crimes can cut him off from society and finally unhinge him. Hidden crimes often produce abnormal behavior in the sinner. Hawthorne in Roger Malvil's Burial reveals that even an apparently harmless act if hidden out of fear, can affect social integration of the individual with the community and family. To him crime itself was not so monstrous as the concealment of it. Roger Malvin's Burial may be called an overture to his grand exploration of this theme in The Scarlet Letter. During military operations, a soldier may have to leave his dying comrade. In such a situation, Reuben is forced to leave his friend, Malvin to di e, as there was no other option for him. However, he had agreed to come and bury him later, after his own wounds are healed. Nevertheless, he lacks the courage to tell Dorcas, who is the daughter of Malvin and his future wife, the fact that her father did not receive a burial in the wilderness. Not burying a fellow soldier in combat conditions is not even a venial sin. However, the hiding of it to his wife and thus to his community prevents him from fulfilling a simple but important social and religious
