Use of Light and Darkness in Joseph Conrads Heart of Darkness Joseph Conrads Heart of Darkness contrasts light and darkness, to represent the civilized and uncivilized sides of the world. Conrad uses light to represent the civilized side of humanity while contrasting the dark with the uncivilized and savage. Throughout the thematic stages of the novel, that is the Thames river London, the companys office in Belgium, the journey to the heart of darkness and the conclusion, light and dark is used to represent these sides of humanity, but on a deeper level many assumptions of darkness and light are challenged, with the appearance of light and dark, and in turn good and evil contrasting with the reality. From the initial†¦show more content†¦From the start of the novel, Conrad foreshadows Marlow journey into the heart of darkness through the use of light and darkness. Marlows journey to the Belgium companys office, where he encounters two women knitting black wool. The two women are commonly interpreted of representing two of the three fates of Ancient Greek mythology who spun, wove and cut thread to represent the birth, lifespan and death of mortals. This darkness used perhaps foreshadows the evil he will encounter, something that merely fate may decide. Marlow describes the place as the city that always makes me think of a whited supulchre, and the city of the dead, thus, white in this instance is used to represent the exploitation of the company and the true evil, which is hiding behind the faà §ade of light and progress. Therefore Conrad uses the civilized white to represent the evil of the dead city and the search for the precious trickle of ivory. The map in the companys office, and the light and darkness associated with it again demonstrates and perhaps foreshadows the good and evil, and the civilized and uncivilized side of humanity. .

John Steinbeck s Of Mice And Men - 1023 Words

In 1949, the Gold Rush brought people from all over pursuing the American dream. A theory defines itself as if you is if you have enough perseverance and will power, you can make anything of yourself in the U.S.A. In John Steinbeck s Of Mice and Men, two migrant workers are still struggling to find their speck of gold. George Milton, a smart, quick-tempered man looks after Lennie, a huge man that is mentally underdeveloped who doesn t know just how strong he is. They have a simple dream of having their own land, which they get closer and closer to until it eventually fails, like many dreams in the Gold Rush. Their dream ultimately breaks down because of Lennie s unconscious and restricted strength which prevents him ever succeeding in his only desire of petting soft things and because like many other migrant workers, they did have enough money. Soft is one of the most common and attractive adjectives used to advertise and describe various things such as clothing and animals. Lennie is extremely entranced by the idea and motion of petting both of these things. Unfortunately, His desire is only matched by his enormous, unregulated strength. Consequently, even if Lennie is gently stroking something such as a mouse, it could abruptly die. Lennie looked sadly up at him. They was so little, he said, apologetically. I d pet em, and pretty soon they bit my fingers and I pinched their heads a little and then they was dead--because they was so little. (9-10).

Rate of Photosynthesis Limiting Factors Free Essays

Rate of photosynthesis: limiting factors Limiting factors The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature. In any given situation any one of these may become a limiting factor, in other words the factors that directly affects the rate at which photosynthesis can take place masking the effects of the other factors. Light and rate of photosynthesis At low light intensities, as light intensity increases, the rate of the light-dependent reaction, and therefore photosynthesis generally, increases proportionately (straight line relationship). We will write a custom essay sample on Rate of Photosynthesis: Limiting Factors or any similar topic only for you Order Now The more photons of light that fall on a leaf, the greater the number of chlorophyll molecules that are ionised and the more ATP and NADPH are generated. Light dependent reactions use light energy and so are not affected by changes in temperature. Rate of photosynthesis Intensity of light As light intensity is increased further, however, the rate of photosynthesis is eventually limited by some other factor. So the rate plateaus. At very high light intensity, chlorophyll may be damaged and the rate drops steeply (not shown in the graph). Chlorophyll a is used in both photosystems. The wavelength of light is also important. PSI absorbs energy most efficiently at 700 nm and PSII at 680 nm. Light with a higher proportion of energy concentrated in these wavelengths will produce a higher rate of photosynthesis. Carbon dioxide and rate of photosynthesis An increase in the carbon dioxide concentration increases the rate at which carbon is incorporated into carbohydrate in the light-independent reaction, and so the rate of photosynthesis generally increases until limited by another factor. As it is normally present in the atmosphere at very low concentrations (about 0. 4%), increasing carbon dioxide concentration causes a rapid rise in the rate of photosynthesis, which eventually plateaus when the maximum rate of fixation is reached. Rate of photosynthesis Carbon dioxide concentration 1 Temperature and rate of photosynthesis Although the light dependent reactions of photosynthesis are not affected by changes in temperature, the light independent reactions of photosynt hesis are dependent on temperature. They are reactions catalysed by enzymes. As the enzymes approach their optimum temperatures the overall rate increases. It approximately doubles for every 10 Â °C increase in temperature. Above the optimum temperature the rate begins to decrease, as enzymes are denatured, until it stops. Limiting factors In 1905, when investigating the factors affecting the rate of photosynthesis, Blackmann formulated the Law of limiting factors. This states that the rate of a physiological process will be limited by the factor which is in shortest supply. Any change in the level of a limiting factor will affect the rate of reaction. For example, the amount of light will affect the rate of photosynthesis. If there is no light, there will be no photosynthesis. As light intensity increases, the rate of photosynthesis will increase as long as other factors are in adequate supply. As the rate increases, eventually another factor will come into short supply. The graph below shows the effect of low carbon dioxide concentration. It will eventually be insufficient to support a higher rate of photosynthesis, and increasing light intensity will have no effect, so the rate plateaus. Rate of photosynthesis Temperature Rate of photosynthesis Higher CO2 concentration; higher temperature. Higher CO2 concentration; lower temperature. Lower CO2 concentration; lower temperature. . Intensity of light If a higher concentration of carbon dioxide is supplied, light is again a limiting factor and a higher rate can be reached before the rate again plateaus. If carbon dioxide and light levels are high, but temperature is low, increasing temperature will have the greatest effect on reaching a higher rate of photosynthesis. Finding out How might the factors that affect the rate of photosynthesis be investigated? Design a suitable series of experiments. 2 How to cite Rate of Photosynthesis: Limiting Factors, Papers
