The effect of Pectinase Concentraton on the production of apple juice
The effect of Pectinase concentration on the production of apple juice The aim of this experiment is to see the effect different Pectinase concentrations have on the production on apple juice. Pectinase is an enzyme which breaks down pectin, a polysaccharide found in plant cell walls. This enzyme is mainly commercially used to speed up the process of fruit juice production as the cell walls of plants are broken down more quickly. Therefore by changing the Pectinase concentrations, the results may show the effects it may have on how much apple juice will be produced. Hypothesis: As the concentration of the Pectinase increases in concentration, there will be more apple juice produced. However, after a certain amount of Pectinase concentrate, the volume and intensity of apple juice produced would not increase anymore because there is a limit of active sites in the Pectinase for the pectin in the cell walls of the apple to react with and therefore the apple juice produced will not increase further. Null Hypothesis: As the concentration of the Pectinase increases there will be no change in the volume or intensity of apple juice produced. Variables: Independent - The concentration of Pectinase (1, 2, 3, 4, 5%) The different concentrations of enzyme will be used to determine whether or not they have an effect on the production of apple juice. By using a range of
Analysis of an extract from Chapter 3 of Arundhati Roy's "The God of Small Things".
This document is an extract from the novel entitled The God of small things written by an Indian author called Arundhati Roy . She's a famous novelist , activist and a world critizen . Moreover , she's well known for her writings criticizing the Indian society . Thanks to her first novel The God of Small Things she won the Booker Prize in 1997 when this novel was published . The text studied comes from the chapter 3 . The scene takes place in October 1962, Ammu was eight months pregnant. The War against China began and people were being evacuated, but Ammu was too pregnant to flee . When the twins were two years old, Baba was drunk most of the time. His English boss, Mr. Hollick, told him his job was in trouble but that they could work something out if Baba went out of town and let Mr. Hollick sleep with Ammu. But Ammu didn't agree with this plan , Babe knocked her down then passed out from being tired and drunk . Then , Ammu took the heaviest book and beat him . This scenario repeated itself a few times, and finally Ammu took the kids and left. At the end Pappachi didn't believe Ammu's story because he couldn't believe that English people can have bad behaviour . Firstly , I'm going to talk to you about Baba's alcoholism . My second part deals with Sexual harrasment . Later , the third part is about the divorce As I Said before on my summary , this part is
Medea Reflection. When I first read the play Medea, I did not have any sort of sympathy for Medea herself.
Status' of Women in Ancient Greece Euripides has been known for writing about women in his plays. In his plays, he shows women trying to redeem their social status in their said country. When I first read the play Medea, I did not have any sort of sympathy for Medea herself. Yes I may have learnt the history of Ancient Greece a long time ago, but when reading the play, the historiography was not there with me. For example, when Jason travels to Colchis to find the Golden Fleece, Medea falls in love with him and helps him. When read without any historical context in mind, it seems as if they will be a good couple, love at first sight; analyses like these come into mind. But after reviewing the historical context, we need to remember that men had not respect for women in ancient Greece times, they regarded them as worthless. While learning this information, I had an epiphany that I should have realized the bad circumstances that are about to fall upon Medea from the first couple of lines. For another example, when there was a rumour that the King of Corinth is going to ban Medea and her children, at that point, I said to myself "good for her", because at that time I put myself in the Kings feet and concluded that if a woman is making trouble in my area, then she should be removed. But then again, as a king I only want my country or area to prosper. But after I found out that
To what extent was the alliance system responsible for the outbreak of World War One in 1914?
To what extent was the alliance system responsible for the outbreak of World War One in 1914? In the events after the end of WW1 much of the blame for the outbreak of the war fell on Germany and their aggression. However with hindsight we see that things were a lot more complex. The idea that many historians except nowadays that the alliance systems caused WW1, but none of them can agree to what extent they caused the war. Before the war began countries started to make bonds and promises between each other, this triggered a lot of factors that sparked the war. In 1914, when the First World War broke out, Europe was divided into two military alliance systems: the Triple Alliance including Germany, Austria-Hungary and Italy, and the Triple Entente that included Britain, France and Russia. The intent of the alliance system was primarily to provide mutual defence in order to maintain the power balance in Europe, but the nations eventually came to rely on it for aggressive purposes. Frictions between the groups had brought Europe to the verge of war several times after 1900, and were indirectly influential in generating a world war out of the Balkan conflict between Serbia and Austria-Hungary. Although the alliance systems were intended to provide mutual defence, they encouraged war equally well by providing military support. In my opinion the most important alliance in the lead
Investigating the relationship between cell size and rate of diffusion
Investigating the relationship between cell size and rate of diffusion Aim: To plan and carry out an investigation to show the relationship between volume, surface area, and diffusion; and to demonstrate, using diffusion, why the size of cells is limited. Hypothesis: In this experiment, I expect to find that when the surface area to volume of a cell reaches a certain level, diffusion alone won't be able to supply the cell materials needed, and as single-celled organisms take in and release substances by means of diffusion across the cell membrane, this process limits cell size. I predict that as the rate of diffusion will be too slow to deliver materials to the center of the cell in the larger cells, it could result in cell malfunction. Variables: In this investigation, the variable I am manipulating, the independent variable are the dimensions of surface area to volume ratio of the agar cube. The variable I am observing/recording, the dependent variable, is the rate of diffusion (NaOH turns the agar cube pink as it disperses into it). The controlled variables will be keeping the concentrations of the Sodium Hydroxide constant, to use agar jelly from the same batch (so the type of agar jelly is exactly the same), and to keep the time even for all cubes so the NaOH has the same amount of time to disperse into the cube. Apparatus: 3 agar cubes containing pH indicator
"In areas of knowledge such as the arts and the sciences, do we learn more from work that follows or that breaks with accepted conventions?"
"In areas of knowledge such as the arts and the sciences, do we learn more from work that follows or that breaks with accepted conventions?" There are many areas in which we may attain knowledge of the arts and sciences. In many cases, it is the knowledge from accepted conventions, which we learn from and develop for stronger understandings in what society has acclaimed to. In such, we assimilate the knowledge at hand and further it for practical purposes that permit a larger understanding in what we determine to be the truth. As well, there are the ideas and sources of knowledge that break away from conformed thoughts and introduce new realms, which have not yet been explored. In this, we settle for a new resolution that offers a new perspective, rather than the predetermined principles widely accepted by society. The knowledge in both these areas is obtained through ones own awareness and familiarity in ones own experiences. Thus, the knowledge is developed through ones own interrelated experiences and affliction with the world in itself. The main purpose here is to determine in which case we learn more and attain more knowledge. In breaking accepted conventions, one may delve into a new phenomenon, which rejects and questions society's current perception. As well, this may become the new thought process in society opening a door to many new possibilities with this new
"In order to find out how things really are, one must understand the filters thorough which one perceives the world" - Discuss and evaluate this claim.
"In order to find out how things really are, one must understand the filters thorough which one perceives the world." Discuss and evaluate this claim. As human beings, we are not born perfect. Our senses, which perceive the world, are limited therefore creating bias and there are other factors such as emotion, and logic, which also filter our perception of the world as it is. The claim to be discussed is, "In order to find out how things really are, one must understand the filters through which one perceives the world." Some of the areas of knowledge in which our perception is limited are the subjects of Biology in the Natural Sciences group, languages, mathematics and the art group. The limitations of our senses and other factors such as emotion, and logic contribute towards the filtering of our perception of reality when perceiving the content of natural sciences, arts, languages, mathematics and various other areas of knowledge. Furthermore, the filtering sometimes may contribute towards the enhanced perception of the material contained in areas of knowledge such as languages, natural sciences, mathematics and arts. In my opinion, the claim, "In order to find out how things really are, one must understand the filters through which one perceives the world", is true to a certain extent, as our perception of various areas of knowledge is altered due to the filtering process.

__________________________________________________________________________________________ "In order to find out how things really are, one must understand the filters through which one perceives the world" Daniel Atkins 20th November 2002 IB-TOK Prescribed Title Mr. D Ford Word Count: 1210 The Oxford Advanced Learning Dictionary defines a filter, as an apparatus for holding back substances. Filters allow something's to pass through them and not others. This word can have many different forms of usage. Yet, when talking about life or how one perceives the world, a filter has a more discrete, hidden meaning. Everyday we filter ideas via the medium of sight, touch, smells, taste and sounds through our head. These senses can be significantly applied to the topic at hand. Although forming the body of this essay with the senses, it can be made easier, by breaking the question down into two manageable questions. How are things really? And what determines the filters through which we perceive the world, and life? An idea has all four senses some how woven into it. An idea is a questioned statement that one could be asking themselves and curious about the outcome of it all. The idea may have positive or negative feedback linked to it. For example, suppose a human being, fed up with life, decided that he/she wants to rob a bank and live off other people's riches. When he/she
"Jonah and the Whale" by Viola Meynell
Jonah and the whale by Viola Meynell The parable of "Jonah and the whale," from the Bible, is a didactic parable intended to teach readers that God loves everyone and anyone who repents their sins will be forgiven. In Viola Meynell's poem, she mainly focuses on describing the qualities of the whale in the first seven stanzas in order to show how the whale symbolizes repentance of sins by God and then adds a twist in the last stanza as Jonah enters the whale unexpectedly. Meynell allows readers to vicariously experience the world of the whale, the majestic king of the lake; she uses various sound techniques, diction with symbolic connotations, and vivid imagery to emphasize the significant features of the "watery world" the whale lives in. Meynell uses an ABAB rhyme scheme where the last word rhymes every other line of a stanza. There are eight stanzas in total, each stanza contains four lines. The first and fourth line of each stanza has nine syllables while the second and third lines contain 10 syllables. Overall, Meynell uses these stanza patterns and rhyming scheme to create a "wavery" effect. In other words, when readers read the poem out aloud, they vicariously feel like the whale 'rocking' through the sea waves. The first five stanzas are dedicated to vividly describe the "watery world" where the whale resides. Meynell chose special diction such as "sported", "rich
Long Days Journey Into Night
Explore the significance of the past in the play "Long Day's Journey Into Night" by Eugene O'Neill At the very start of Long Day's Journey Into Night, O'Neill sets the scene for the theme of the past being integral to the play directly with the dedication to the love and tenderness of his wife - "... which gave me the faith in love that enabled me to face my dead at last and write this play - write it with deep pity and understanding and forgiveness for all of the four haunted Tyrones." This admittance that the play was written as a sort of autobiography, a partial re- telling of O'Neill's personal history, means that it seems almost intrinsically connected to the past right from the beginning, the intimation from the author being that he wrote it as a form of catharsis in order to deal with the real events from his own life. Consequently the theme of the past is introduced before even the first Act has begun. The idea that he is 'facing his dead' is a particularly apt one as at the time of writing the play, the people upon whom its characters are based - O'Neill's family - had all passed away some years before. His father, mother and elder brother Jamie are all portrayed in the same roles in the play as they had in real life, and with similar histories. The only alteration is that instead of the middle son being named Edmund, O'Neill changes the baby's name to his own, and
