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

Rights of Third Parties Case Study Example | Topics and Well Written Essays - 3000 words

Rights of Third Parties - Case Study Example Contract is an agreement or set of promise between two or more persons which is binding and therefore legally enforceable. It covers transactions like buying and selling, employment of staff, partnership agreement and so on. It can also be described as: "an agreement which is legally binding on the parties to it and which broken may be enforced by action in court against the defaulting party. Existence of contract - Damages sought by claimants on the basis of fraud and breach of fiduciary duty in respect to diverted insurance premiums - Negotiations between the parties taking place after proceedings issued - Letter sent by claimant asking whether defendant accepted responsibility for the fraud - Letter signed and returned by defendant but with caveat - Whether binding agreement concluded between parties. Willis Management (Isle of Man) Ltd v Cable and Wireless plc [2005] 2 Ll L R 597 (CA/UK) A trust is an equitable obligation, binding a person (who is called a trustee) to deal with property over which he has control (which is called the trust property) either for the benefit of persons (who are called beneficiaries or cestuis que trust) of whom he may himself be one, and any one of whom may enforce the obligation, or for a charitable purpose, which may be enforced at the instance of the Attorney-General, or for some other purpose permitted by law though unenforceable. Pettit Equity and The Law of Trusts 8th ed. (1997) p 24. CONSTITUTION OF TRUSTS Constituting the Trust - act of vesting the trust property in the hands of the trustee. If inter vivos transferor will vest the property concurrent with declaration of trust, If testamentary property will vest upon testator's death in executors/administrators, - Rule - if trust not constituted, it is invalid- Problems: A declares trust in favour of B on Day 1, but doesn't transfer $$ to trustee until Day 5. - Rule - until the trustee receives the property, trust incompletely constituted invalid - Curative: On day 5, trust valid & operative b/c trustee has property - Settlor can be compelled to transfer property they promised to place in trust - where S received valuable consideration for promise to create trust RIGHT OF THE THIRD PARTY The Contracts (Rights of Third Parties) Act, which was given Royal Assent on 11th November 1999, radically changes a fundamental principle of English law, namely that only those who are parties to a contract can enforce rights under that contract - the 'privity of contract' rule. The Act applies to virtually all contracts. Therefore the construction industry must consider its impact on all its contracts - building contracts, subcontracts, consultants' appointments, collateral warranties, insurance policies, bonds, adjudication agreements etc. Right of third party to enforce contractual term: The third party must be expressly identified in the contract by name, as a member of a class or as answering a particular description but need not be in existence when the contract is entered into. This section does not confer a right on a third party to enforce a term of a contract otherwise than subject to and in accordance with any other

Genetically Modified Organisms - Essay Example An organism that has been subjected to such genetic manipulation is referred to as a genetically modified organism. Genetic modification involves the altering of the DNA code in a cell that is artificially grown in a laboratory before being reinserted into the same organism or an unrelated organism. The totality of genetic information that is present within the DNA of an organism is called genome, and this information is coded in such a way that it can be understood by all other living species. According to this coding system, four nucleotides are required to provide instructions to a cell on how it is to make any protein. (Steinbrecher, 1998). Nucleotides are DNA units whose names are listed as letters – A, C, G and T. The arrangement of these in three letter words is equivalent to the code for specific amino acids. Within each gene, there are also regulatory elements which function as flags to control gene activity. Each gene also has an information block, which prevents gene activity from moving in an unusual direction. As a result, gene regulation is specific to the context of its environment.(Steinbrecher, 1998). The process of genetically modifying an organism, which transports a gene from one organism into another, must also provide a means to circumvent the information block with cells of each organism, in order to provide recognizable flags or control sequences, which the other organism will recognize and accept. This is accomplished through the use of viruses, which are able to integrate their own DNA information into a host cell and cause it to multiply. This occurs due to the presence of powerful promoters in the viral cells that force the host cell to read viral genes and produce viral proteins, thereby producing construct or combined genes that can be used to produce desired changes in an organism (Steinbrecher, 1998). One of the most common examples of genetically modified organisms are crops such as pest resistant

The Companies Act Essay Example | Topics and Well Written Essays - 4500 words

The Companies Act - Essay Example Not only the shareholders and directors of the companies being freshly incorporated but those of the companies that are already in existence need to study the general duties of the directors in the Act. Executive Summary: The companies Act in 2006 are a pioneering law contemporary times that places great moral and social responsibility on the directors of the companies. Definitely, UK has taken the lead in calling for a more mature and responsible behavior on part of the Directors of a company. The Companies Act 2006 replaces the companies of 1985 and 1989. The Act, it is hoped, will usher in an era of the more responsible role for people in business leading to â€Å"enlightened shareholder approach†. The shareholders will hold the directors more accountable for their acts leading to the generation of awareness for the social and physical environment. The government feels that business atmosphere, society, and the environment are inextricably linked to each other and the positive or negative fallout of one affects the others. The registration of companies started in 1848. Earlier in the Companies Act of 1948 originated the â€Å"True and Fair View† (Bucheery, n.d.). This entailed upon the directors to give a true and fair view of the fiscal position of the company and the profit and loss were reflected in the annual balance sheet for the knowledge of shareholders. Later this system was incorporated in the fourth directive of Company Accounts of the European Economic Commission (Flint, 1982). Earlier the refrain in the corporate world was to maximize profits at any cost. But with the world coming together due to globalization and the experience of negative fallouts of the trade and commerce like emission of greenhouse gases, deforestation, and a yawning gap between the developing and the developed world, a need was felt for enactment of a law that required greater business transparency, a commitment to the social and physical environment and reinforcement of confidence of the people in business sys tems.

It has developed over 200 companies across the globe and deployed 120,000 employees in these companies (Award, 2010). The corporate strategy aims at improving the Johnson & Johnson’s structure through proper organizational design. The design has led to the formulation of a decentralized divisional structure which has encouraged the proper flow of information. It has also enhanced working relationships between activities and functional department. Furthermore, the decentralized divisional structure has allowed different stakeholders with different skills to bring together different technologies and products. This has led to satisfying the unmet needs of customers (Award, 2010). Synergy has assisted the Johnson & Johnson to acquire sustainable competitive advantage. The CEO Weldon has come up with a decentralized divisional structure to foster synergy. He has used the structure in assessing external environment to identify a number of forces. The first one is demographic that determine how population growth have affected demand of Johnson & Johnson’s products not only across New Brunswick, USA, and New Jersey but also in 60 countries in the globe. The second one is socio-cultural factor that examine social issues such as poverty that affect the purchasing power of Johnson & Johnson’s products by the people in the globe (Award, 2010). The third one is technological factor which determines the available healthcare technology such as Cougar Biotechnology and breast implant maker. The next factor is political which examines the requirement that local and national authorities expect Johnson & Johnson to meet in supplying and handling health care products.

Financial Management Discussion Week 7 Essay Example | Topics and Well Written Essays - 500 words

Financial Management Discussion Week 7 - Essay Example Prototyping being the first stage requires entrepreneurs to keenly listen to prospective customers. Cheap and simple prototypes, however, should be built for the purpose of acquiring customer feedback. This level advocates for invested labor and credit card borrowing to finance the venture. At this stage trying to produce any venture capital would be fruitless except when the business can prove that it may make profits at early stages (Brooks, 2012). A vivid business model should follow the proof to offer a powerful bargaining upper hand with a venture capitalist. Customer base is useful especially after finding a customer who is willing and capable of paying for the final prototype. Also if one might want to ask capital from angel investors or family members who might want to buy a lesser stake in the particular company. At this level, the business or entrepreneur can raise money from many people who cannot scheme to oust the founder. Some Companies start g capital at this level even though it is advisable to wait and proceed with the activity at the third stage (Lawrence, 2010). Expansion is another process implemented after acquiring a trivial share of the market segment and surprisingly when also the growth of the company becomes stunted. Acquiring a new market becomes a vital activity while developing and updating products. At this level the startup CEO is in a position to discuss with capital providers because the venture is lucrative. The exit is the final process where the entrepreneur sells the business to a customer or gives a public offering (Baron, 2011). Sadly after the initial public offer is done most entrepreneurs leave their business because of the boredom brought about by the administration of a sluggishly growing publicly traded business. A company can raise capital using various ways for different uses depending on the financial necessities or on the size and nature

Read chapter Nighn 9 and answer the questions - Essay Example These musicians were responsible for promoting Nueva Cancion in support of an intensive leftist protest that expressed distaste for a totalitarian and capitalist regime as well as imperialism which occurred to corrupt the nation’s cultural identity at that period. As a turning point in the history of the movement, the presidential campaign of Salvador Allende in 1970 became sensationalized especially as it managed to convey the leader’s strong Marxist convictions through an open election in which the Nueva cancioneros contributed rhythms that thematically coincided with Allende’s communist principles. At the time, the government may be perceived as a government of revolution which responded in utter agreement to the combined political ideals and musical creativity of the radical artists. The short-lived administration and the forerunning characters of the Nueva Cancion were of a single heart and passion in being pro-people so that their joint forces, as a whole, were accounted for as highly significant in Latin American history, having influenced the world with songs that communicate advocacies for human rights, anti-oppression, ethnicity, liberation, anti-poverty, and non-dictatorial martial rule. As an unfortunate consequence, however, the brutish takeover of the powerful military coup some three years later fated Allende and supporters, Victor Jara, and some fellow artists with a tragic end of death. The coup reacted to this extent of employing harsh measures toward Nueva Cancion as the movement had been viewed widely with the ample capacity to move and educate communities and turn them against their unrighteous rulers as vividly evident for instance in the crafts of Jara via lyrical substance of the pieces â€Å"Venceremos† and â€Å"El aparecido†. (2) What is a wawa velorio? Why is it a celebration? What takes place at this ceremony? (What types of activities and what type of music.) (1/3-page) Basically, the term ‘ wawa velorio’ pertains to a child’s wake that is presented in a ritualistic manner and in particular, J.T. Titon describes it as an all-night affair for the wake of the deceased Quichua child. To illustrate the chief ground behind the rationale of its celebration, Titon states that â€Å"The death of young children in Ecuador and throughout Latin America is a daily tragedy, one that through its very frequency ironically serves to preserve dozens of unique regional traditions of genre, instrument, and dance.† Based on this, a thoughtful reflection may be inclined to figure that the sadness of such regular tragedy must have been too much to bear that families and the rest of the community prefer to celebrate with music and dynamic colourful activities rather than mourn over their grave loss of tender-aged loved ones. Apparently it makes sense, for when Latinos are gathered as such, they may be alleviated of a huge portion of burden as singing and dancing could fun ction as a tribute to the dead and a natural yet sacred acknowledgment of mortality and life’s severe misfortunes. During the ‘wawa velorio’ event, according to Titon, a harpist and a golpeador or wake singer are hired to play vacacion – a music sharply rendered with percussion instruments and sanjuan, respectively. While vacacion is purely instrumental and is solely played by the
