Solutions of starch and amylase were held at selected temperatures by various methods of temperature control. Once the solutions reached and maintained the desired temperature they were combined. Samples at timed intervals were then taken and reacted with a reagent to determine the effect the selected temperatures had on the reaction rate of enzyme and†¦show more content†¦A constant temperature water bath will be needed to maintain temperature. All enzymes and starch solutions will be maintained in the optimum pH so as to ensure a fair test (REFER TO FIG-32). The following is an EEI designed to test the effects of temperature on the activity of the enzyme Amylase. This experiment on enzymes was done to help convey how environmental factors affect the activity of an enzyme. The experiment will revolve around changing one variable (temperature), measuring one variable (color of the samples in the spot plate/reaction rate/time) and keeping everything else the same (optimum pH/volume of reactants and the reagent). To test the effects of temperature on the activity of amylase, solutions of the enzyme and starch will be reacted with each other at controlled temperatures 70oC, 50oC, 37oC, room temperature and 4oC and below. To find out what effect these temperatures have on the activity of the enzyme, a sample of the resulting solution will be taken at allocated times and be placed onto a spot plate where a test for starch will be done by adding iodine reagent. The relative enzyme activity in the spot plate will be assessed as follows: Iodine test for starch | Amount of starch remaining | Enzyme activity level | Yellow/gold | NONE | NORMAL 5 | Light purple/silver/grey | SOME, | MODERATE 4 | Tan/lightShow MoreRelatedHow Heat Affects Lipase1180 Words   |  5 PagesFactors Affecting Enzyme Action ------------------------------------------------- Term 1 Biology Nicole Goosen Table of Contents Introduction: 3 Materials: 3 Method: 4 Risk assignment: 4 Risk: 4 Personal Protective Equipment: 4 Results: 5 Discussion: 5 Conclusion: 6 Introduction: How is the human body able to digest the food that you eat?

In doing this paper, I found the researching more grueling. It is definitely not easy to find out more about the history of Dublin and how they were subjugated by the Britain force. That history is abounding with details that need not only an understanding from the surface. We will write a custom essay sample on The requisite of a good research in making a good paper or any similar topic only for you Order Now I also had to establish the correlation between these historical facts and the literatures of James Joyce which he wrote to reflect these facts. Meticulous research on James Joyce, his biography and his works, were also needed. I needed that to see the personal context where Joyce was coming from in doing Dubliners, the book which I chose to use in this paper. The difficulty of research is certainly coming from the fact that I have to inform myself with various details which I had to put under a careful interpretation. This interpretation needs to be done to see exactly how literature asserts its presence in the material world where separate events maintained by different groups of people also exist. Once I have collated the details I gathered, all that is left for me to do is to streamline and organize these details and see the corpus of information I currently have. From there, I already did my outline which finally gave direction to the paper I wrote. Writing the actual paper is not really hard since I am already equipped with a good amount of information which I have already organized. Once I begun facing the computer monitor, the words I needed instantly come into light and I suddenly found myself done with the paper. In conclusion, doing the research is much harder since this is the first step in doing a well-informed paper. This part of the writing process will determine the information that will be included in the final paper. Definitely, a good paper selects the information it will share and a scrupulous research is needed to refine this selection of information.

The Ancient Myths about Athena

The Ancient Myths about Athena In his mythology (The Age of Fable: Vols. I II: Stories of Gods and Heroes. 1913), Thomas Bulfinch uses the Roman name Minerva for the Greek goddess Athena. Chapters from Bulfinch that Feature Athena: Chapter 14Arachne and the Weaving Contest With AthenaThe beginning of this chapter details Athenas skills, her special connection with Athens, and her birth from the head of her father Zeus. The chapter goes on to describe a contest between a mortal woman, Arachne, and Athena. It follows with another challenge made by a mortal against a goddess, but the goddess is not Athena.Chapter 15MedusaBulfinch has already identified Athena in the previous chapter, so in this one, Athena is introduced as the goddess challenged by Medusa to a beauty contest. Regardless of who was more beautiful, Athena had to punish Medusa, which she did by turning her into a monster. Then, when the hero Perseus goes off to slay the monster, Athena comes to his assistance by lending him her shield the one he uses as a mirror so he can decapitate without being turned to stoneChapter 30Odysseus and AthenaIn this chapter, Bulfinch is describing the adventures of Odysseus. Odysseus has returned to Ithaca but doesnt recognize it until Athena in disguise tells him where he is. The chapter describes Odysseus return to his home where he finds and eventually slays the suitors who have been harassing his wife. Elsewhere in Bulfinch, Athena plays minor roles: Chapter 16Athena invents thunderbolts and deals with the winged horse Pegasus.Chapter 20Theseus blames Athena for abandoning Ariadne and sets up the Panathenaea to honor her.Chapter 2Here Athena helps Prometheus steal fire to give to mankind.Chapter 19Athena and Hermes accompany Hercules to the Underworld.Chapter 7In this chapter, Bulfinch invents a conversation between Aphrodite and her son in which she names Athena as one who defies her.

Thomas a Kempiions, The Imitation of Christ(Book2) Essay

Thomas a Kempiions, The Imitation of Christ(Book2) - Essay Example The book had been written at much more troubled time than our own and makes a soulful reading. Book 2 touches meditation, humility in life, the need of goodness and peace in man to live life on this earth, necessity of purity of mind and heard and unity of purpose etc. It mainly focuses on self of the reader and the resultant happiness by having a good conscience. It reminds the necessity of loving Jesus, friendship with Jesus, and not desiring to have a share in comfort. It teaches how to appreciate God's grace and his blessings. It preaches the need to love the cross as the symbol of sacrifice and suffering and choose the path on the 'Royal Road' of the Holy Cross. The main point of the book is "God is within you" and the necessity of despising external things. "He who follows me, walks not in darkness" The Treatise says that by devoting self and making the inner kingdom ready for Christ, an individual can invite God to himself2. The first chapter calls for the renouncement of all external worldly belongings to devote time and energy for the spiritual devotion and heavenly thoughts3. The second chapter is about its humility and its uses4 and how much God loves a humble individual. It says that the humble man keeps his conscience clear, suffers in silence, and finds the protection of the God5. The third chapter mainly talks about the goodness and peace in man. ... It says how important it is to be good even to bad people, because it is easy to be nice to the good and difficult to tolerate the bad. Unless one has inner peace, it is impossible to achieve peace for others. It needs great mental strength to treat both kinds of people with the same understanding7. The fourth chapter is about the purity of mind and unity of purpose and it brings forth the importance of simplicity and purity and the need to be free from ill-ordered affection. If the heart is pure any deed could be achieved and anything could be perceived with great clarity8. With pure heart, it is possible to achieve all the joy in the world. Fear of toil, welcoming external comfort, and growing lax will make the individual more sluggish. Instead, he should welcome suffering to attain inner light9. Chapter 5 is about self and the about the need to put our inner house in order, hold tongues about others10, and avoid relying too much on self. It is it is necessary to free self from all temporal cares and treat everything on equal footing11 and regard only God as the superlative of all. The sixth chapter is about the joy of a good conscience12, which is the glory of a good man. Sinners can never rejoice and there is no peace for the wicked and this shows how important it is to maintain a clear, non-reproaching conscience13. It is necessary for the man to think inwardly with good motives, without caring for praise or blame, to do good and think little about it14. The seventh chapter is mainly about loving the God, who is the ultimate true friend, and it is necessary to cling to him till the final breath because Jesus needs your pure heart15. All other outward appearances in which we trust will show one day that they are deceitful and untrustworthy. Chapter 8 once

Financial Management Individual Work 1 Week 6 Essay

Financial Management Individual Work 1 Week 6 - Essay Example In this case, operating leverage reflects the intensification of the upper part of the revenue statement with the fixed costs being the costs of business procedure and that are not affected by alterations in sales. Within financial and income aspects of any business, working income is a component of business risk. For instance, with two indistinguishable firms and one firm utilizes higher operating advantage with all other things remaining constant, the firm experiences less predictable return on asset and operating income, and this results to elevated risks to the business. With an elevated business threat, the stock- and bondholder are affected (Brigham & Ehrhardt, 2010). Financial leverage involves the degree of utilization of fixed charge securities within the capital structure of a given firm. High financial leverage occurs when the capital structure of a firm is characterized by elevated debts and preferred stock. In this case, the extent of entity sales characterized by equal costs and revenue presents the breakeven point and breakeven analysis can be done with or without financial costs (Brigham & Ehrhardt, 2010). This way, the financial leverage represents the underside half of the revenue statement entails changes in EPS relative to alterations of EBIT. Financial leverage accounts for some aspect of corporation risk through debt financing. Through debt financing, a business is prone to variations in earnings prior to taxation after interests thus elevating earnings per share and the net income. Corporate risk is thus a summation of business risk and financial risk. Modigliani and Miller revealed that whether leveraged or not, firms should have equal value in the absence of taxes and other costs. Further, organizational value and weighted standard capital costs will be free of the capital structure (Brigham & Ehrhardt, 2010). Consequently, constant
