Critical Analysis of After Apple Picking by Robert Frost
IOC: Robert Frost After Apple Picking This extract comes from North of Boston, a selection of poems from the eminent American poet Robert Frost. Like most of the other poems in the book, Frost's After Apple Picking reads like a short drama. Like The Mending Wall or the Woodpile , this poem is narrated from a first-person point of view, where the poet refers to himself as "I" and is a principal actor in the poem- continuing to describe his setting, emotions and thoughts throughout. Frost, who is renowned for his figurative use of language, is sometimes counted amongst the ranks of the transcendentalist poets. Transcendentalism often amounted to drawing upon an individual sense of consciousness whilst eschewing the intellectualism of the day. A greater spiritual appreciation was appraised for the setting that influenced the transcendentalist and, thus, North of Boston is imbued with a dreamy quality whilst still retaining a vivid appreciation of nature. It is also interesting to note that some literary critics have called the transcendentalism an "American Romanticism" movement- and indeed, many of Frost's poems have a strong inclination toward nature combined with aesthetic appreciation for emotion and feeling. After Apple Picking is, in itself, a marvelous representation of Frost's philosophy and writing style- though it is somewhat unfortunate that no definite
Osmosis Internal Assessment (Biology)
BIOLOGY INTERNAL ASSESSMENT STANDARD LEVEL OSMOSIS OSMOSIS IN POTATO STRIPS i. Aim To investigate the change in the mass of potato strips as a result of the process of osmosis in potato strips over varying periods of time. ii. Research Question How does time affect the mass of potato strips (measured in grams) when immersed in distilled water (H20) over a period of five hours at one hour intervals: 1 hour, 2 hours, 3 hours, 4 hours, and 5 hours? iii. Introduction Osmosis is the passive movement of water molecules from a region of high water concentration to a region of lower water concentration (lower solute concentration to higher solute concentration), across a partially permeable membrane.1 The plasma membrane is selectively permeable, and it controls the movement of substances in and out of cells, but water is able to move freely in and out of the cell, allowing osmosis to occur.2 Potato cells have selectively permeable membranes and therefore can be used to show the process of osmosis. As plant cells generally have a higher solute concentration than their surroundings (lower water concentration), when immersed in H20, the potato strips will be surrounded by a region of high water concentration since water has a solute concentration of 0.3 This would mean that the distilled water is hypotonic whereby it has a higher concentration of water than the potato cells,
How do Medea and Hedda Gabler combine tradition and unconventionality within their roles as women in a constraining society?
How do Medea and Hedda Gabler combine tradition and unconventionality within their roles as women in a constraining society? The eponymous characters featured in both Medea and Hedda Gabler have perpetually been cast as unconventional women, defying every aspect of feminine behaviour expected of them in their respective societies. However, in truth, both women conform to convention far more than it would seem, albeit in contrasting ways. Medea dreams of the same future as any ordinary Greek woman would even despite her refugee status. In the end it is circumstances that drive her to the unexpected and terrible acts she commits. Hedda differs within her relationship with the culture surrounding her and fights at it. She is forced to live the life of a traditional woman in her society and hates it, as we shall see, she makes any effort she can to escape it. This combination of propriety and unconventionality contribute to the power of both plays as tragedies. There is some debate, though, on whether the playwrights intentionally did this, or, due to the cultural era they inhabited, they could not possibly see women totally unshackled from their roles in society. Medea appears to be a traditional wife in many ways therefore the cataclysmic breakdown of her marriage with Jason is more of a surprise to the reader; the way in which it dissolves into such violence. Throughout the
IB BIOLOGY INTERNAL POTATO OSMOSIS
Aim: To investigate the effect of changing solute concentrations on the process of osmosis in potato chip of a given size. Hypothesis: I predict that as the solute concentration increases, the mass of the potato will decrease because due to osmosis, water has the tendency of flowing to an area of low concentration from an area of high concentration, and as the solute concentrations increase, there will be a lower concentration of water in the solution, hence the potato mass will decrease. The independent variable in this experiment will be the solute concentrations. Water and sugar solutes of 0.1, 0.3, 0.6 and 0.8 mols -1 will be used in the experiment The dependent variable in this experiment will be the mass of the potato chips after osmosis compared to before the osmosis. There are several controlled variable worth mentioning. Make sure all potato chips used are of the same length, by measuring each with a ruler. Use only solid, whole potato chips, check the solidity by observing each chip. Measure the quantity of solutes used with a measuring cylinder, and measure at eye level to obtain accurate measurements, use the same amount of solute for all types of concentrations. Control the time period allowed for osmosis, by timing with an electronic timer from the exact moment the chips are placed in the solutes. The cups used for the solutes must be completely dry before
Biology: Lab report Germination
Biology Lab Report Seed Germination By: John Abarshi (Figure One: Cress Seed Germination) Introduction This term, we embarked upon our first biology experiment. Recently, in class, we have been learning about plant reproduction. Amongst the vast amount of information pertaining to the topic of plant reproduction is germination. Germination is the process of sprouting, whereby seeds or spores sprout or emerge and begin to grow. [1] [2] When a seed is germinating, certain factors affect its germination. It was our task to come up with two variables that could influence seed germination and to investigate this. After much contemplation and consideration, I managed to pinprick what factors I would like to investigate. I will thus investigate if altering the light and temperature of the cress seeds' environment will affect the germination. Research Question How do light and temperature affect the germination of a cress seed? Hypothesis If cress seeds are placed in a dark environment, then their germination will be negatively affected compared to cress seeds grown in a normal light environment because seeds If cress seeds are placed in an environment with excessive exposure to light, then their germination will be positively affected compared to cress seeds grown in a normal light environment because seeds If cress seeds are placed in a cold environment, then their

examine the causes and effects of biodiversity loss in tropical rainforests Biodiversity refers to the variety and quantity of all forms of life on Earth such as plants, animals and micro-organisms. It is estimated that there are up to 30 million different living species on Earth and more than 50 percent of these species live in the tropical rainforests. (rain-tree, N/A) Tropical rainforests play and important role in the world's natural environment as well as human society, as they not only provide a safe home for numerous plants and animals and help stabilize the world's climate and nature, but also also are a great source for medicines and foods. However numerous lives in tropical rainforests are at risk due to human deforestation. Deforestation in tropical rainforests as the major cause of the tragic loss of biodiversity, mainly happens due to globalization and cattle ranching, hydroelectric power, migration and logging. As a consequence, the ecosystem is disrupted, soil is eroded, carbon dioxide levels are increased and the nutrient cycle is affected. Globalization and cattle ranching is one of the major causes of loss of biodiversity due to deforestation in tropical rainforests. Meanwhile, industrial countries continue to develop and the demand for cattle is rapidly increasing. Over the past 25 years, rainforests have been cleared from an area the size of the entire

Character development of Shukhov in One Day in the Life of Ivan Denisovich
Character development of Shukhov in "One Day in the Life of Ivan Denisovich" Ivan Denisovich Shukhov, the protagonist of the novel 'One Day in the Life of Ivan Denisovich' is a prisoner in the Soviet prison camp. He was caught by the Germans during the Second World War with perfidy when he tried to come back to Soviet lines. He spent earlier time of his imprisonment in Ust-Izhma camp and then in the "special" political camp. The special political camp was in the hands of harsh and abrasive authorities. Shukhov has spent eight years and he has enough experience of most of the tricks that can be used in the camp for the survival. He knows all the legerdemain of the harsh camp system, how to get extra food or other favours but he sticks to his moral principles of doing things so that there would be no harm for his self-respect. He actually adapts his own ways of survival in the camp. Shukhov was a farmer when he was in his home, in his own free life he used to think about the farming, buying horses and haymaking etc. It shows his agricultural experience and also shows his hard working life of being a farmer. As his life starts to move on, his carriers and thinking also changes with respect to his position. Then he became soldier of the Second World War but after that he could not go to his free living life of farmers and captured by Germans. Now, the life and thinking
Macbeth Critical Response Essay
Macbeth Critical Analytical Response If Hollywood ever dared to take a second attempt at making Macbeth into a movie, it would probably have to be rated 18A. Aside from the violence, and other mature content the amount of blood present in the play would be enough to deter any viewers under 18 years of age. However, just as violence is necessary in every action movie, blood plays an essential part in Macbeth. In his play Shakespeare uses blood as a symbol for guilt. Using this symbolism in combination with the behaviour and actions of his two main characters, Macbeth and Lady Macbeth; Shakespeare is able to clearly communicate his theme that one's ambition in combination with certain circumstances may compel one to respond with acts of evil, and as a result these people may be consumed and destroyed by their resulting guilt. At the beginning of the play Macbeth is introduced as brave, honourable and loyal, a great general who fought loyally to defend his king. When the sergeant introduces him for the first time, he is referred to as "brave Macbeth" the sergeant goes on to praise "well he deserves that name". In the first few scenes ambitious Macbeth is praised to the point where it seems he can do no evil. It is not until Macbeth is confronted by a special set of circumstances presented to him by the Witches does he begin to have dark desires and evil intentions. "All hail,
