Size and Complexity of an Animal - Essay Example The essay "Size and Complexity of an Animal" talks about the fundamental aspect of animal growth and the relationship between the growth in size and the surface area relative to its volume. The relationship between surface areas to volume ratio is best exemplified by reflection on phylum Porifera. The organism has a smaller surface area in relation to its volume. As a result, it depicts a simple form of exchange with the external environment. For example, nutrients are taken directly from water then enters through pores by cells lining the organism. On the other hand, complex organisms have a larger surface area to volume. As a result, these animals have trouble in acquiring nutrients. Therefore, they have developed a complex mechanism of feeding such as mesoderm in platyhelminths. The development of larger and complex bodies posed a challenge in respiration. The reason is that smaller animals such as sponges could take gasses directly from the surrounding water. As a result, there was no need for a development of the specialized organ. The challenge arises, as organism could not exchange oxygen and carbon dioxide directly with their cells. Moreover, in platyhelminths, the development of flat body enhanced efficient exchange of gasses through diffusion. The flat body help in providing a high surface area to volume ratio and hence easy supply and exchange of gasses. On the other hand, higher animals could not maintain gas exchange through their body surface. As a result, diffusion was not possible on their body surfaces.

Comparison of the Presentation of the Characters Jay Gatsby and Dick Di

Comparison of the Presentation of the Characters Jay Gatsby and Dick Diver from The Great Gatsby   Ã‚  Ã‚  Ã‚  Ã‚  F. Scott Fitzgerald is known as a writer who chronicled his times. This work has been critically acclaimed for portraying the sentiments of the American people during the 1920s and 1930s. ‘The Great Gatsby’ was written in 1924, whilst the Fitzgeralds were staying on the French Riviera, and ‘Tender is the Night’ was written nearly ten years later, is set on, among other places, the Riviera. There are very interesting aspects of these works, such as the way Fitzgerald treats his so-called heroes, and to what extent we can call them heroic.   Ã‚  Ã‚  Ã‚  Ã‚  Gatsby and Diver are both presented as wealthy men leading privileged lives. ‘The Great Gatsby’ was written before the Depression, and the optimism and faith in the power of money within the novel demonstrates this belief that people had. Notably, it is the characters’ faith in riches, and not Fitzgerald’s own. Gatsby is a self-made millionaire, making his money through bootlegging. He has acquired vast amounts of money, and believes that this money will help persuade Daisy to love him and leave Tom. This is illustrated in Chapter five when Daisy is shown around Gatsby’s mansion at his request. He shows her every detail, through from the gardens to his shirts and ‘he revalued everything in his house according to the measure of response it drew from her well-loved eyes’. Gatsby sees his money and possessions as wonderful things, but they are also more than that, they are a means to an end, the end being Daisy. He bough the house because of where it was in relation to Daisy (across the bay), and he held the most amazing parties in the hope that Daisy, or someone that knew Daisy would come. Gatsby, in effect, devoted his whole life to the search for Daisy, and his money is a tool to help him find his love.   Ã‚  Ã‚  Ã‚  Ã‚  Diver’s attitude to money is very much a contrast to this. Money to him does not represent freedom and choice, but a bind that ties him and constricts him. Diver is conscious through the whole novel that he himself is not the financially dominant member of his marriage, but Nicole, with her seemingly endless riches. ‘Tender is the Night’ is written after the Wall Street Crash and during the Depression, but Fitzgerald has moved his characters away from the Depression of the United States to the French Riviera... ... ideal. Again and again, Fitzgerald underlines the importance of faith and hope, without which America and the American Dream mean nothing, and it is impossible to survive without. Diver and Gatsby can both be seen as the failure of the American Dream, and thus that the America that was supposed to be a place where everything is possible, where freedom and liberty come above all else, is failing herself. In Jay Gatsby and Dick Diver F. Scott Fitzgerald has presented us with tow men who should not fail, who, if there is any justice in the world, should succeed in what they do. However, they do not. Granted, they are not perfect, but they are more heroic and noble that the other characters they are surrounded with. The reason they do not survive is because they are old-fashioned men, with old fashioned, romantic ideals, and they are destroyed by the cruelty and superficiality of modern America. Fitzgerald does not paint a very reassuring picture of his home country, and these two novels display his personal fears about American society. ‘Tender is the Night’ and ‘The Great Gatsby’ are two novels grasping the mood of the moment, and Gatsby and Diver are two men who cannot keep up.

Chinese dream and my dream Essay

â€Å"There would be no new China without the Communist Party†, I’ve heard of this saying since I was a little child. From then on, the Communist Party has left a deep and giant impression on me. China makes great progress under the leadership of the Communist Party which has always been the belief of China. I’ve been told that it would be a great honor to be a party member. So now I am a party member and the Chinese belief becomes my genuine belief. However, as growing up, I begin to wonder whether all the party members can regard the Communist party as their belief all the time and whether they are doing the things the party member should do. The answer is so disappointed. The power of Chinese belief and the awareness of Chinese people of supporting the belief are becoming weaker and weaker. China needs a firm and strong advocate of the belief. Many people can establish the belief of becoming a party member, but they can’t follow their original belief all the lifetime. Gradually they lose themselves in the debauchery lives and they forget what they have said under the flag. Other people without party affiliation are harder to see their own belief clearly. A nation without definite belief is lamentable and horrible because it can be easily destroyed by the outside rumor. Chinese dream of need a power to hold the belief is the same as my dream. We are facing the similar situation. It is easy for me to set up a goal, but I can’t carry out the goal from beginning to end. Sometimes the obstacles or the outside environment make me give up the goal. I lack the perseverance. I lack the power to hold the goal. I’ m a member of the Communist Party, but I’m not true of the name for the reason I’ve mentioned above. After many years, I’ m afraid of becoming the kind of person I disliked before. I’ m afraid of losing myself in the busy world. I’ m afraid of forget all the dream and belief made when I was young. I really need the power to help me hold the belief. China is developing and I’ m growing. We all share the same dream. China needs the citizens to awaken themselves and I need the self-awakening. The glamour of the surface must be very vulnerable. We should be tested by the time. Only holding the belief all the time can we go further towards the success. Chinese dream is my dream. Hoping the dream comes true.
