An Investigation to Show the Effects of changing temperature in Yeast Respiration Essays

An Investigation to Show the Effects of changing temperature in Yeast Respiration Essays An Investigation to Show the Effects of changing temperature in Yeast Respiration Essay An Investigation to Show the Effects of changing temperature in Yeast Respiration Essay Yeast is one of the various single celled fungi that form masses of miniature circular or oval cells by budding. When placed in sugar solution the cells multiply and convert the sugar solution into alcohol and carbon dioxide. Yeasts are used as fermenting agents in baking, brewing and the making of wine and spirits. Brewers yeast is a rich source of vitamin B.Respiration in yeast is the production of the energy in the mitochondria of the cells. There are 2 types of respiration, Anaerobic and aerobic. At first aerobic respiration will be present but only until the oxygen that is already dissolved in the water. When the oxygen is used up anaerobic respiration will be present which produces the alcohol. The word equation for anaerobic respiration in yeast is:Glucose Alcohol + Carbon Dioxide + EnergyAnaerobic respiration is different in humans than it is in yeast because we break down glucose into lactic acid whereas yeast breaks it down into alcohol.Input Variabl esThere are several different variables in this experiment such as:The temperature of the waterAmount of WaterAmount of YeastAmount of sugarThe time it is left forIn this experiment I will be changing the temperature of the water.PredictionI predict that the hotter the water is the more carbon dioxide bubbles will be produced because the hot water will produce more kinetic energy so it increases the chance of collision. If we heat the sugar solution too much then the enzyme will change shape and it will become impossible for it to join with the sugar to form a complex. This is called denaturing the enzyme, I predict that this will happen at 70 80 C.PlanFirst I will set up the apparatus as show above. I will add 1.5 grams of sugar to 25ml of water and dissolve it. When we have the water at the correct temperature I will add the same amount of yeast to the sugar solution. When the water is at the correct temperature I will let it stand for 5 minutes. The first test I am going to do w ill be at normal tap temperature (20 C). I am going to increase the temperature by 15 C each time until I get to 80 C. I will measure the amount of respiration by counting the carbon dioxide bubbles entering the second test tube.Fair TestTo keep this investigation fair I am going to:* Keep the amount of sugar and yeast the same throughout the investigation* Keep the amount of water the same throughout the investigation* Let the solution stand for the same amount of time each time, five minutes* Add the yeast only when the sugar solution is at the correct temperatureSafetyThis investigation isnt very dangerous; I will only have to be careful when handling the hot water.AnalysisFrom my results you can see that the yeast reacts better between 35-50 C. This is because at 20 C the water was too cold to give the enzyme any energy. At 65 C there was not much reaction, I recorded an average of 2.5 bubbles of carbon dioxide. This was because the water was too hot and when the water is too ho t the enzyme deforms and changes shape as shown in my prediction diagram. It gave off a few carbon dioxide bubbles at the beginning before it changed shape so maybe at 50 60 C the yeast will react better as it didnt change shape straight away. At 80 C the water was far too hot, this would have changed the shape of the yeast straight away. I know this because we only counted one carbon dioxide bubble for the whole of the experiment.Quality of ResultsI think that my results were precise. I know this because I measured the yeast and sugar with electronic scales. The water was an accurate measurement as well as I used a measuring cylinder to measure it. Another measurement that was accurate was the temperature of the water as we used a thermometer so I knew when to add the yeast. The final results were another accurate measurement as I completed the same test three times.Was It A Fair Test?This test was fair because:* I used the same amount of yeast for each test* I used the same amoun t of water for each test* I counted the bubbles for the same period of time each test.The only thing that wasnt fair about the test was that I had to use different types of yeast. For the first and second tests I used yeast that was in small balls (not ground) and for the third test I used a powdered yeast but was still the same brand. I dont think this changed the outcome of my results much as we got similar results for the first, second and third test. The only difference that may have been was that the ground yeast started to respire earlier as it was smaller, therefore easier to dissolve! Another reason that could have made my test unfair was that when the yeast was first added it was dormant and dehydrated. I had to wait for it to start to respire, but this was the case in all the tests so in a way it was fair.Accuracy of MeasurementsAll of my measurements were accurate. This was because I used an electronic set of scales to weigh the yeast and the sugar. Another reason why my test was accurate was that we used a thermometer to check the temperature that is an accurate means of measuring heat. It would have been even more accurate if we used an electronic thermometer.Improvements to PlanThe only major improvement that I think would have been useful would be to increase the temperature by only 5 C each time instead of 15 C. This would help us to get a more accurate measurement of when the yeast respires best. If I had more time I would have done this and would have been able to find the optimum temperature for the yeast. Another improvement would have been to measure the amount of carbon dioxide given off instead of counting the bubbles. This would have been a good improvement as bubble sizes change, they are never the same size.

Inflation Literature review Example | Topics and Well Written Essays - 1250 words - 1

Inflation - Literature review Example The markets had assumed that the debt by Euro zone was safe. This made the investors think that all members thereby making them willing to maintain debts even at low interest rates despite countries including Italy and Greece having high debt levels had backed them. After the credit crunching, the investors began being to be more skeptical about the European finances. The other unfortunate occurrence was that the European Union had no strategies in place to deal with the sudden panic. The diagram below shows some debt from Selected European countries between 2007 and 2010. Pettinger on the economics journal of October 2011, tried to analyze the Euro economic crisis critically where he applied a single currency meant that several of the solutions regarding economic problems could not be used. The most difficult task is to reduce the government borrowing levels while managing lower unemployment and economic recovery. He studied several European economies including Greece, Ireland and Portugal and found the following problems. Pettinger best-suggested solution was currency devaluation. This refers to the reduction in the value of exchange rates .This would see regaining of competitiveness, reduction of budget deficit, increase employment rates, and aid in economic recovery. Since economic recovery is the key to reduction in budget deficit. He suggested that Countries should stop the use of the Euro and maintain their own currency. Most countries agree that the renewal of the economic growth is vital in saving the Euro (Pettinger, 2012; Pg. 68). The obstacle is that the effects of steps such as having a banking union, the recently agreed rescue plan may have positive effects to the banking system but may not have any effect to raise the competitiveness in the region’s economies. The second option was inflation, where the country should try to boost

Social desirability effect Essay Example | Topics and Well Written Essays - 500 words

Social desirability effect - Essay Example Field study is one of the methods employed by researchers in studying human behavior. Field studies are undertaken in a natural setting rather in a structured environment (Kitayama & Cohen, 2010, p. 220). It involves a naturalistic observation wherein researchers discreetly observe behaviors that occur in a natural setting. Field study also entails observation of individual’s reactions to stimuli or events designed by researchers in the natural setting (Kitayama & Cohen, 2010, p. 220). This particular method of study is interesting as it offers an in-depth detail of a social phenomenon. However, the results derived from these studies fail to provide objectivity as it relies on the researcher’s judgment. The means to improve such method become an interesting area of study. Field study can serve as an insightful means of defining group behaviors. Wimmer and Dominick (2010) stressed that field studies possess an advantage of being nonreactive. Reactivity refers to the effe cts of the subject’s awareness of being observed or measured on her or his behavior. The objectivity of studies often suffers from subject’s awareness of being observed (p. 225). Sevilla, Ochave, Punsalan, Regala, and Uriarte (1992) reiterated that there are variables in social psychology that cannot be explored through experimentation (p. 154). Thus, field study offers insights into these phenomena. It presents a great breadth and depth of understanding unattainable by quantitative researches (Shepard, 2004, p. 50). Shepard (2004) stressed that findings in a particular situation may not be applicable to other situations. In addition, most field studies fail to employ standardized measuring devices. Researchers rely on subjective interpretation and judgment. The researcher’s judgment is vulnerable to biases and blind spots (p. 50).

Magazine Content Analysis - Essay Example Some magazines target the minority while others target the majority. Indeed, we have minority-targeted magazine like the Black Enterprise magazine and mainstream-targeted magazines like BusinessWeek magazine. This paper presents a content analysis of minority and mainstream magazines. In doing so, the paper will explain how advertisement in minority-targeted magazines and mainstream-targeted magazine by establishing the similarities and differences there in. Ideally, advertising produces magazines that target diverse audience. A mainstream-targeted magazine refers to a magazine with a huge readership and demographic categories while minority-targeted magazine relates to a magazine with limited readership and few demographic categories. In the recent times, the number of minority-targeted magazines have been increasing subject to the appreciation, increase, and buying power of the minority. Indeed, advertisers have realized the potential in the minority and have since tailored different advertisements targeting their needs, perception, and potential. The frequency and quantity of minority-targeted magazines have led to an intrusive and consistent mode of advertising that the minority cannot afford to disregard. Some of the minority-targeted magazines include the Black Enterprise magazine, African American Golfers Digest, Black Collegian Magazine, and Black Men Magazine. With respect to the Black Enterprise magazine, we can establish that the magazine is more prominent in black neighborhoods. The magazine has a capacity to reach about 6 million people and hence the need to analyze the content of the adverts contained in the magazine. The content in Black Enterprise magazine seems to target Black Americans and their needs. Notably, the magazine contains adverts of cigarettes and alcoholic drinks that suit the social needs and purchasing power of the blacks. Most notable is the fact that adverts in the Black Enterprise magazine

Feminism in Fifth Business

Feminism in Fifth Business The role of women in the novel Fifth Business is essential and fundamental to the character development and spiritual meaning that Dunny seeks throughout the novel and whether they shape and influence his life in a positive or negative way. Dunny remains in the background essential to the action but not a principal, interlaced in a thread of numerous subplots and themes. Dunny peruses his passion for hagiology which sets him on a journey of discovery through a path of materialism and spirituality plagued by his consistent guilt which carries an underlined theme throughout the novel. The importance of women is consistent throughout the novel since his upbringing in the town Depthford onwards and we will see these women sculpting, damaging or setting him free. The roles of the women will be analyzed through the view of Dunny and how they contributed to his development. The novel Fifth Business which is written by Robert Davies and although they are entirely unalike in character similar experiences enclosed in a fictional reworking of arrangements and situations are consistent with the life of Robert Davies specifically with a similar childhood in a small town in Ontario which give you an account of his thoughts, emotions and experiences in a deeper sense. First, Dunnys mother is a determined and controlling person with a strong and strict Calvinist belief who raises Dunny accordingly which fits her role as a protecting and loving mother who likes to help others, until their situation drastically changes when the focus of her love changes and isolation coupled with resentment builds after the snowball incident with the Dempsters family. This is evident, when Dunny states I began to believe that I was more responsible for the birth of Paul Dempster than were his parents, []. Part of that dreadful fate would undoubtedly be rejection by my mother (Davies 17). Undeniably, his mothers love and focus begins to change attention towards the Dempsters family instead of her own household which initiates Dunnys feeling of isolation and begins to feel resentment for his mother who is unable to provide consolation for his adolescent heart. Furthermore, Dunnys mother continues the passage of isolation and it is particularly felt when Dunny responds Being unofficial watchdog to the Dempsters family was often a nuisance to me and did nothing for my popularity (Davies 22). Obviously, the feeling of isolation is felt by Dunny and it affects his social life with his friends and himself as a person in the future. Next, Dunnys mother imposes fear on his juvenile youth and the resentment for his mother arguably evolves to hate when he is severely beaten by his mother and replies I have been very miserable since-miserable not for an hour but for months on end-but I can still feel that hours misery in its perfect desolation, if I am fool enough to call it up in my mind (Davies 29). Consequently, this incident causes an atmosphere of tension throughout the rest of the novel whenever Dunnys mother is mentioned and he instead turns his attention and love towards Mrs. Dempster. In the long run, Dunnys mother is responsible for his deep isolation, his stance on women, and the insecurities around them which boundaries his feelings and emotion s throughout his life and does anything only through obligation and nothing out of desire for himself which is the reason for his life being miserable and despiteful leaving him unable to form lasting relationships with women and relatively unattached to his mother and women in general. Second, Mary Demspter is considered Dunnys first love and a simple women and more so after the incident with the snowball which is the reason Dunny carries the plague of guilt with him throughout the novel but in essence the guilt remains with himself alone which is a weak cause to hold it against Mary and claim it as her role for she is not the reason it occurred. On the contrary, with that established let us not overlook that Mary plays arguable one of the most vital roles in the novel as Dunnys inspiration for the path of mythology, saints and longing for knowledge and inner spirituality. This begins, with the second miracle when Mary has supposedly raised Willie from his deathbed and Dunnys response to himself is For me, Willies recall from death is, and will always be, Mrs. Dempsters second miracle (Davies 57). Undeniably, to Dunny this is seen as a complete miracle whether anyone believes him or not and will commence his journey of mythology and validating Mary as a saint. Furt hermore, is apparent with the first miracle that occurs but is not known until later when Dunny reencounters Joel Surgeoner and discuses the miracle with him and Joel acknowledges, He worked through that women, and she is a blessed saint, for what she did for me-I mean it as I say it-was a miracle (Davies 135). Clearly, this acceptance of Mary as a saint without a doubt in the eyes of Joel who is forever changed since that night leaves a strong impression on Dunny and motivates him in continuing his direction in the path of mythology and to comprehend the complications and serious possibilities of Mary being a saint. In addition, the third and last miracle is during the war when Dunny is about to lose consciousness and during this time has visions of Mary and her being the Madonna statue but does not fully acknowledge it till later in the novel when he contemplates to himself that, [H]er miraculous appearance to me when I was at the uttermost end of my endurance at Passchendaele (Da vies 161). Without doubt, Dunny is talking within the context of the 3 miracles and confirms to himself that the vision of Mary was the third and final miracle and might be all the proof that he needs to convince himself that it is so but his conviction also plays a destructive influence yet on the other hand brings him academic and personal growth and pleasure. On the whole, Mary plays a critical role providing the three miracles that occur and essentially changes his life profoundly while recognizing her as wholly religious and his experience with her offers him a greater insight about the nature of a life lived with the knowledge of the presence of the mythic world in the actual world and reassures his childhood interest in mythology and saints to come to the forefront of his life and career. Third, Diana Marfleet plays a significant role in the novel as his first meaningful and realistic love but more importantly gently guides him in his self-transformation with the change of his name and being with her made him realize what he really wanted in life and she helped him mentally with the damage that his mother has caused. Plainly, it is clear when his self-transformation begins as Diana is taking care of him and he receives the news of death of his family during the war due to the influenza epidemic of early 1918 and Dunnys remark to himself was, It was years before I thought of the death of my parents as anything other than a relief; in my thirties I was able to see them as real people (Davies 78). It seems that Dunny is finally able to escape his mother even though it was through death it was something he has been longing for and finds great freedom in it while finding closure at the same time during the care of Diana. Also, Dunnys time with Diana helps his figure out wh at he wants to do with his life now that he is physically and mentally able with the care of Diana by his side and the freedom he has just received. Distinctly, being with Diana has made him think about himself for once in life and made him realize that he loves Diana but is not in love with her and that is when Dunny mentions to himself That decision, made at that time, has shaped my life and doubtless in some ways it has warped it, but I still think I knew what was best for me. In the long periods of rest in the hospital I thought as carefully as I could about my situation (Davies 85). Certainly, he is referring to the decision he has made with Diana and how things would not work out between them in the future because she is too similar to his mother which he just got rid of and does not want another. Moreover, to complete his transformation she decides that he should change his name to Dunny which mentally gives him the psychological push to complete and realize his transformatio n into a new person when his reply was I liked the idea of a new name; it suggested new freedom and new personality (Davies 90). Unmistakably, Dunny has taken a liking to his new name which was changed from Dunstable to Dunny and enjoys the freedom and the possibilities that it holds and he remains grateful for what she has made him realize and done for him which no other women has so far. To sum up, it is ironic that consequently Diana who was the one to sever the link between Dunny and his mother by renaming him does not end up marring him and more so because his mothers full name was Fiona Dunstable Ramsay. Nevertheless, his relationship and time with Diana has matured him and broaden his scope of life, understanding and culminated in his rebirth and renaming. In conclusion, the role of women have been extensive and necessary throughout the novel and has matured and turned Dunny into the man he is today although his mother has been the root of the problems in his life the majority of the women have been a positive influence on Dunny and will forever change his outlook on women and life. Dunny has remained and fulfilled his role as Fifth Business by bringing resolution or meaning to the story or merely by observing or explaining it. Throughout the novel he was always the odd man out and continually searching for meaning and significance in life whether it be from his mother who molded him during his childhood, Mary who gave him a lasting connection with the mythology, magic, and the inner spirituality of one self and life or Diana who gracefully opens and heals his heart and mind regarding women and himself again. Ultimately it is an incredible quest for knowledge and happiness which he has finally found even though it was a long and tiring journey with many sacrifices.

The Power And The Glory :: essays research papers

The Power and Glory writing assignment   Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"The spirit is willing but the flesh is weak†.(Matthew 26:41) These words of Jesus are thematic in both the novel, The Power and the Glory, by Graham Greene, and the poem, â€Å"Batter my heart, three-personed God†, by John Donne. Both the whiskey priest and the speaker of the poem are involved in a battle between their sinful flesh and their spirit, which seeks the Divine. They also admit their sin and commit themselves to God. In both the novel and the poem, the authors use similar paradoxes to describe the character’s relationship with God while the search for holiness takes each on a different path. The speaker and the whiskey priest describe themselves as sinners, yielding to temptation. The speaker of the poem says, â€Å"But I am betrothed unto your enemy†(ln.10), showing the speaker is subdued by the devil. The priest, a drunkard with a child, thinks of himself as a transgressor and a disgrace to the Church. While in the prison, the priest says to the pious woman, â€Å"But I’m a bad priest†¦I know from experience-how much beauty Satan carried down with him when he fell.†(p.130) When he is arrested the priest says to a soldier, â€Å"You mustn’t think they are like me†¦It’s just that I’m a bad priest.†(p.191). In addition to recognizing their betrayal of God, they believe that a sacred life is the ultimate victory. The speaker confesses, â€Å"Yet dearly I love you and would be loved fain.†(ln.9) The priest also desires to love God above all, â€Å"He knew now at the end there was only one thing that counted – to be a saint.†(p.210) However, each character pursues the Divine in a different way. Even though the whiskey priest perceives himself as a sinner, his way of life resembles the good of the Holy Spirit. The priest resembles Jesus in many places in the novel. The prison scene is very much like the Last Supper, when Jesus said to his apostles that one of them would betray him. The priest thinks, â€Å"Surely one of these people will betray me first.†(p.128) He also cleans the pails of the cells in the prison just as Jesus washes the apostles’ feet. The night before he is executed the priest prays alone as Jesus did in the garden. The priest embarks on a mission to keep his religion alive in Mexico while helping the individuals he meets, and he finally dies because of his faith and sense of duty.
