Investigation on the size of Limpets.
Investigation on the size of Limpets Abstract: During my preliminary investigations, I established that sheltered and exposed rocky shores, differed immensely in their size of Limpets. Thus I was inspired to compare the size of Limpets on the sheltered rocky shore, Frenchman's Steps. The background knowledge and preliminary work enabled me conclude the following hypothesis; there will be a statistically significant difference between the size of limpets found on the sheltered rocky shore at two different vertical heights. I decided to look at 3M and 6M above chart datum for my investigation, as looking at the profile graph (appendix) the number of limpets was high at that chart datum. Aim: To determine if there is a difference in the size of limpets at two heights in there Vertical range. Scientific Background Limpets are animals that belong to the family Patellidae, subclass Prosobranchia of the phylum Molluscs. They have a strong, conical shell composed mainly of calcium carbonate, protecting the internal tissue, underneath which is a sucker, also known as the limpet foot, which allows limpets to adhere to rock surfaces, as shown in the photographs. Limpets are usually immobile unless they are foraging and so zonation is less apparent. As can be seen from the pictures above, limpets have a hydrodynamic shape so that resistance to water flow is reduced. This
Poetry from different Cultures
Essay Describing Devices Used in 'Blessing' When we read poems, very few people actually take in the devices used and make sense of the way the poet uses them and still fewer people take the time to decipher why the poet has used that specific device in that specific place. The devises often have hidden meanings, and are used to make the poem flow better. In this essay, I will be describing, analysing and evaluating why and how Imtiaz Dharker has used the devices she has incorporated into the 'Blessing'. The title of the poem alone, 'Blessing' is a strong word which could mean that what happens in the poem is special, almost like a miracle, which helps set the mood of this poem very early on. The first line, 'The skin cracks like a pod' is not only an effective simile, but it's a way of setting the scene and cultural aspects of the poem as the first image of a pod that comes to mind is a cocoa pod, which cracks in the sun's heat or is cracked open to get to the cocoa beans. The cocoa pod is from somewhere like Africa. In the second line, the way the words are placed really emphasises the word 'never' as it catches you out when reading out loud. You would normally say that phrase as 'is never', but in this poem, to emphasize the rhythm and the word 'never' the sentence is 'never is'. In the second stanza, onomatopoeia plays a fairly big part, taking over 3 words, 'drip',
Deducing the quantity of acid in a solution
Sofia Gaggiotti Chemistry coursework: Deducing the quantity of acid in a solution 20/03/2008 Index Aim and Background information 3 Hazards 3 Protection 4 Method 5 Previous calculations 5 Making the Solution 6 Equipment needed 6 Quantities of materials needed 8 Procedure 8 Making the Titration 9 Equipment needed 10 Procedure 13 References 15 Results and calculations 16 Evaluation 19 Chemistry coursework: Deducing the quantity of acid in a solution Aim and background information The aim of this experiment is to find how to develop and determine an accurate, precise and reliable concentration of an acid rain solution. 1 To do this, we are going to make first a solution of sodium carbonate with distilled water and then a titration in order to calculate the concentration of sulphuric acid in a solution. Solution: a solution is a homogeneous mixture composed of two or more substances. In this mixture, a solute is dissolved in a solvent. Solutions are characterized by interactions between the solvent phase and solute molecules or ions that result in a net decrease in free energy. 2 Titration: a titration is a laboratory technique by which we can determine the concentration of an unknown reagent using another reagent that chemically reacts with the unknown. At the equivalence point (or endpoint) the unknown reagent has been reacted with the known reagent.
Common Law and Equity
Outline the development of common law and equity. A The Law in England didn't come about all at once, but has developed over the centuries. There are 5 different sources of law: Customs, Judicial decision, Acts of Parliament, Delegated Legislation and, most recently, European Law. However, new law is still being created today. The law as we know it today all started in 1066, when William the Conqueror invaded England. He found a country with no single system of law, just sets of customary rules which differed from area to area. This was due to the different invaders who had settled in different parts of England, bringing their laws with them. William decided to set events into motion that helped bring about the system we have at present. William introduced the feudal system, in which all land belongs to the king, and he slowly started to gain control of England. He then split the land up and granted parts of the land to people who supported him and who were willing to grant him services, e.g. barons. He then made them pay taxes to him yearly. They in turn granted land to their followers and then them to theirs. This meant that the king had gained control of the whole country. The King's Justice was introduced for any landholder who had a problem that could not be sorted with their landowner. They were able to apply directly to the king, and William made himself available

To do so I will carry out an experiment, this will look at the effects of Osmosis on chips of potato in a sucrose solution. The experiment will involve placing identical potato chips into different sucrose solutions with varying concentrations, after 45 minutes, I will take the potato chips out of the solutions and weigh them, changes in mass would indicate Osmotic activity. My aim is as follows: "To investigate the effect of varying concentrations of sucrose solution on the amount of osmotic activity between the solution and a potato chips, identical in size" I hope that by the end of the investigation, I will have a better understanding of osmosis and a conclusion that demonstrates that knowledge.

Follower by Seamus Heaney
Follower Seamus Heaney The follower is written by the Irish poet Seamus Heaney, the poem is about the poets love and admiration for his father. The poem is also about the changes that occur between father and children as children move out from their parent's shadow. We learn a lot about both the relationship that existed between them and the way Heaney saw his family. In the first half of the poem Heaney presents us with a vivid portrait of his father as he appeared to the poet as a young boy. The poet, as a young boy, follows his father as he goes about his work and like most boys, he idolises his father and admires his great skill, ` an expert` with the horse-plough and Heaney as a little boy would simply get in his fathers way. In the poem, Heaney looks up to his father in a physical sense, because he is so much smaller than his father, but he also looks up to him in a metaphorical sense. This is made clear by the poet's careful choice of words. 'His eye narrowed and angled at the ground, mapping the furrows exactly.' These words effectively suggest his father's skill and precision. We are also told that young Heaney 'stumbled in his hob-nailed wake,' which brings to our mind a picture of the ploughman's heavy boots, the carefully ploughed furrow and the child's clumsy enthusiasm. The poet uses onomatopoeic words to capture the details of his father as he works the
Genetically modified crops - Do we know all the answers?
Genetically Modified Crops. Do we know all the answers? Genetic Modification is the method of obtaining individual genes, which are then copied and repositioned into another living organism to modify its genetic code and incorporating or removing particular characteristics into or from an organism.1 There are many viewpoints on the issue genetic modification, some scientifically based on environmental factors and potential economic growth, others concerning ethical, moral and social perspectives. Ever since the breakthrough of genetic modification, deliberation has surrounded all issues involving this controversial topic. Many organizations have published books, videos, and leaflets arguing their side of this debate. Advances in GM biotechnology, such as the incorporation of the gene which stops the Arctic Flounder from freezing, has been placed into the genetic sequence of strawberries to stop them shrivelling in the cold British weather2, these 'modifications' have led to many intrinsic and extrinsic moral issues arising from this "new" technology. Dr Robert Farley of the Monsanto Institute, USA3 believes that genetic modification of crops for human consumption is a much more efficient and effective way of creating more resilient wheat crops than traditional cross-pollination. This is because genetic modification is more specific in changing a particular gene,
A View From The Bridge Essay
A View from the Bridge - How does Arthur Miller show tension escalating during Act 1? Tensions exist in families because of arguments and disagreements occurring between parents and their children especially teenagers, about boyfriends and the way they dress, which refers back to Eddie and Catherine Carbone's disagreement in the first scene when Eddie comments on Catharine's skirt. 'A View from the Bridge' was set in the 1950s in an Italian American neighbourhood under the Brooklyn Bridge in New York. The area, which the Carbone family lived in, was called 'Red Hook'. It is a poor place where crime, gangsters and the Mafia had been well known in recent history. Tension in the Carbone household is present right from the beginning of the play and the narrator, lawyer and family friend Alfieri warns the audience of a tragic ending in his opening speech. Alfieri also gives us some background information on the Carbone family and it sets a mood to the start of the scene. Alfieri introduces the play, narrates the story in flashback, focussing on key scenes, and then closes the play. Arthur Miller himself says, " I wanted to write a play that had the cleanliness... the clear line of some of the Greek tragedies." Meaning that the audience would be confronted with a situation and that the audience would be told in the beginning what the ending was. The question was not what was
How does Steinbeck present the character of Crooks in the novel 'Of Mice and Men'?
How does Steinbeck present the character of Crooks in the novel 'Of Mice and Men'? Within the time period of the 1930's, many non-white people kept themselves isolated from others and stayed out of trouble, to avoid the risk of being lynched. Segregation, isolation and racism was a normal lifestyle led by those who were black; one of the characters that embodies this theme in the novel is the character of Crooks. Other themes of the novel are the American Dream; which is never achieved by any of the characters, this suggests that Steinbeck believed that the dream was unbelievable. This is the same belief which Crooks has. Friendship is another important theme, as the reader sees the desperation Crooks has for friendship and the affect of loneliness has had on him. Steinbeck set the novel in Soledad, California, 1930's during the Great Depression. This is an ironic setting because the term 'Soledad' means isolation and loneliness in Spanish, reflecting the life led by Crooks. Also the reader follows the protagonists Lennie and George as they struggle financially. In addition unemployment rates were high and pension rates decreased; making life hard especially for the middle class. Many men left their families and travelled across the country to find work and support their families. But life was harder for black men as they were seen as savage animals and were not wanted;
Why did so many people die in the 2010 Haiti earthquake?
On the 12th January 2010, a tragic 7.0 magnitude quake on the Richter scale struck near Port au Prince in Haiti. This devastating earthquake was caused by a conservative plate boundary which had not caused an earthquake for 200years. 3,500,000 people were affected by the quake, 220,000 were estimated to have died, and over 300,000 people were injured. Over 188,383 houses were badly damaged 105,000 were destroyed by the earthquake (293,383 in total) and 1.5m people became homeless. After the quake there were 19 million cubic metres of rubble and debris in Port au Prince which was enough to fill a line of shipping containers stretching end to end from London to Beirut (The capital of Lebanon). Furthermore, 4,000 schools were damaged or destroyed and 60% of Government and administrative buildings, 80% of schools in Port-au-Prince and 60% of schools in the South and West Departments were destroyed or damaged. The impact of this was one of the most devastating anyone had ever witnessed. However, why did San Francisco earthquake (Loma Prieta) in 1980 which was magnitude of 6.9 in the Richter scale only cause 69 deaths compared to the death toll of 220,000 in Haiti? The area with the most damage, Port-au-Prince, was built on loose sedimentary rock, which amplifies the seismic waves and intensifies them. We can see how much extra damage the loose sediment does as houses that were
