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,

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

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,

Comparison of emma and charls in madame bovary

Madame Bovary Similarities and differences of Emma and Charles In the first part of the novel, Madame Bovary, written by Gustave Flaubert, there are two main characters introduced to us; Emma Rouault and Charles Bovary. These two characters marry and become the "Bovary's". They both have interesting characteristics that lead to being opposing characters. In part one, we come across several descriptions of appearance, personality, education, background, and attitudes; that help us analyze these. The novel starts off with an introduction of what type of person Charles was during his childhood at school and what his classmates thought of him. Since a very young age, Charles had always been a very educated and respectful person towards others but always showed to be very insecure. He was described as "[...] country lad [...] taller than any of us (pg15)". Therefore you can see that his class mates didn't really accept him because he was different as for his physical appearance, character and style of dressing. The narrator talks to the reader as a school mate which sat in his class and observed him very carefully, he is also described as a forgettable child which shows that his presence didn't remain in people's minds. During his school years, Charles tried his best to attain the best results he could as he had never received a primary education- They "[...] postponed sending

Examine the causes and the effects of biodiversity loss in the Tropical Rainforests

Examine the causes and the effects of biodiversity loss in the TRF Biodiversity can be defined as the variety of all forms of life on earth (plants, animals and micro-organisms). The tropics are the richest areas for biodiversity as tropical rain forests contain over 50% of the worlds species in just 7% of the worlds land. They account for 80% of the world's insects and 90% of its primates. Even though biodiversity benefits us humans in countless ways we tend to be oblivious to this fact and instead, the biodiversity on earth is gradually diminishing. There are many reasons for the loss of biodiversity and the most prominent include Globalization & Cattle Ranching, Hydroelectric Power (HEP), Migration and Logging. Similar to how there are numerous causes for the loss of biodiversity, these causes also have many drastic effects. As mentioned in the introductory paragraph, globalization and cattle ranching is one of the major causes for the loss of biodiversity. Globalization can be defined as the world coming together for trading purposes. This contributes to the loss of biodiversity as globalization is directly linked with deforestation. For instances, huge global corporations like McDonalds own countless amounts of cattle which are often located in deforested areas. In addition to this, much forest land in the Brazilian Amazon is also deforested in order to enable the

Enzyme Coursework. Investigation to find the effect of substrate concentration on the rate of an enzyme controlled reaction

Investigation to find the effect of substrate concentration on the rate of an enzyme controlled reaction Design Aspect 1: Defining the problem and selecting variables Investigation title: is the rate of an enzyme controlled reaction affected by substrate concentration? Background information Enzymes are often referred to as "biological catalysts", since they increase the rate of reactions in living organisms. Enzymes are also substrate specific, which means that only a specific substrate can fit into its active site (which is where the catalysing effect occurs) and as such, there are different enzymes which deal with different reactions (for example, protease breaks down proteins into amino acids) - this is the basis for the 'lock and key' theory. The stages of an enzyme controlled reaction are: ) Enzyme + substrate The enzyme and substrate are in solution together 2) Enzyme substrate complex A substrate has moved into the active site 3) Enzyme product complex The reaction has taken place, but the products haven't been released from the active site 4) Enzyme + product The enzyme and product are now in solution together (after the product was released from the active site) The rate of an enzyme controlled reaction are mainly affected by: temperature, substrate concentration, enzyme concentration and pH. By increasing the substrate concentration, there is a higher

King Lear Passage Analysis Act IV, Scene 7 (lines 26 - 69)

IOC: King Lear Act IV, Scene 7 (lines 26 - 69) Contextualisation of Extract Lear is driven to insanity by his daughters Goneril and Regan as they systematically stripped him of whatever prestige he had left, reducing his entourage from 100 to 50 to 25 to 10, 5, 1 and finally to nothing, at which point they cast him into the storm (III,2), which he in "hell-black night endured". He is then discovered by Gloucester who sends Lear, Kent and the Fool to Dover where he might be safe from his daughters. Upon reaching Dover, Lear runs from the Gentleman and two of Cordelia's attendants fearing capture. It can be inferred that Lear has been caught by the attendants as he enters this scene, "asleep in a chair carried by servants". Significance of Extract In this extract, Lear is finally reunited with his "joy" Cordelia for the first time since his banishment. Although Lear has descended completely into madness, he has finally realised his true state as a "poor, weak, infirm and despised old man" as well as gained a stronger sense of moral awareness and judgment. A touching reconciliation between Cordelia and Lear is seen. Lear is dressed in royal robes and is carried to Cordelia while asleep. I will be analysing three aspects of this extract - The characterisation of Cordelia - The portrayal of Lear's restoration (both physical and mental) - The depiction of Cordelia and
