Photosynthesis In Plants Essay Example | Topics and Well Written Essays - 500 words

Photosynthesis In Plants - Essay Example Three leaves of the bouquet were covered by aluminum foil ensuring that the foil was blocking light from the leaves. The foil was removed from one leaf every week, photographed and observed for the three-week period.ResultsIn Figure 1, the leaves were green and healthy. Figure 2 shows leaves that had turned to light green and almost white in color. Vascular bundles were clearly visible in addition to the green spots on the leaf. The color at the center of the leaf was lighter than the periphery. Figure 3 shows leaves that are brown and dried out.DiscussionThe findings indicate that light is necessary for photosynthesis. The leaf in Figure 1 was green and healthy despite being covered by the aluminum foil because the energy in the chloroplast could still sustain photosynthesis. The leaf in Figure 2, was turning light green to indicate minimum photosynthesis was taking place. The leaf in Figure 3 had been covered for a longer period of time and the energy needed for photosynthesis was depleted. Moreover, there was no more light energy that could be absorbed for photosynthesis. This experiment shows that a low light intensity leads to a low rate of photosynthesis. This would deduce that an increased light intensity would lead to a high rate of photosynthesis at an optimum level.ConclusionIn summary, photosynthesis is essential for plants. Therefore water, temperature, light intensity and carbon dioxide should be made available to ensure the survival of plants.

The Acquisition of Tense by Arabic Learners of English Language Thesis Proposal

The Acquisition of Tense by Arabic Learners of English Language - Thesis Proposal Example This proposal was motivated by an interest in the subject as well as the knowledge that the results of the study are potentially productive and could provide necessary knowledge in the area of linguistic science. This subject is a problem of significance for the students it affects and the knowledge to be gained from this study stands to benefit more than the population of peoples with Arabic as a first language. It is my hope that the findings of this study will also be used to assist other L2 students, and perhaps enrich their relationship with a second language. Among the problems faced by English students with Arabic as their first language is the acquisition of tenses. The morphemes of the English language differ greatly from those of Arabic, and the irregularities of tenses must be memorized, making the acquisition of tenses one of the most difficult parts of the learning process. As stated by Johanne Paradis, this situation â€Å"†¦is a vulnerable domain for English lang uage learners across acquisition contexts†¦Ã¢â‚¬  Since one of two allomorphs pertaining to the past tense is possible, either [td] or [t or d], the English past tense exhibits a quasi-regularity. These combined attributes create difficulties for the would-be English learner. To appreciate the hardship of the L2 student, data will be collected from thirty students at three consecutive levels of ability. Two approaches will be taken while analyzing the data in an attempt to prove two hypotheses.... Since one of two allomorphs pertaining to the past tense is possible, either [td] or [t or d], the English past tense exhibits a quasi-regularity (McClelland). These combined attributes create difficulties for the would-be English learner. To appreciate the hardship of the L2 student, data will be collected from thirty students at three consecutive levels of ability. Two approaches will be taken while analyzing the data in an attempt to prove two hypotheses. Problem Statement: Learning difficulties arising for L2 students can affect certain aspects of their lives. In the case of foreign students, attempts to integrate into a new country can be inhibited by linguistic difficulties. "knowing a language involves mastering an intricate system full of surprising regularities and idiosyncrasies." (Sag and Wasow, 2001) For people attempting to learn English as a second language, it can be embarrassing and often debilitating to incorrectly express tenses. In the workplace, people with English as a second language are often misjudged as unintelligent. Added to the difficulties most adults have with the correct acquisition of phonological sounds, (Escudero, 2005) the learning of English for Arabic speakers is quite a challenge. The confusion of past tenses was one of the major errors in tenses reported in a study of Arab learners of English at the University of Sudan (Kambal, 1980). Therefore, a study concerning the acquisition of English tenses by Arabic students can assist students with similar problems by determining the most effective solution. Hypotheses: There are two hypotheses which will be used to attempt an explanation of the difficulties that

Gender Roles in Children’s Books: An Examination of Little House in the

People use several different classification systems to help organize a complex society. For example, scientists use a system composed of hierarchies in order to place animals in their proper kingdom, phylum, class, order, family, genus, and species. By creating this classification system, people of society are better able to understand the relationships that these animals have with each other. Just as scientists use this hierarchy to organize animals, people use the concept of gender to classify their own kind. However, many people fail to realize that gender, unlike the system of hierarchies used by scientists to classify animals, is not biologically based. While sex is a biological concept, gender can be defined as the sociological, psychological, and cultural attributes that society associates with sex. Thus, society creates gender roles, and, accordingly, â€Å"does gender.† In other words, people require that others act out the gender roles set by society if they want to be part of the social norm. The purpose of this paper, then, is to first examine literature which discusses ways in which society â€Å"does gender†, and then examine the manner in which authors of children’s books promote these gender roles that society has assigned. Judith Lorber’s article entitled, â€Å"Night to His Day: The Social Construction of Gender† (Lorber, 1994) is one example of a piece of literature that examines â€Å"doing gender.† In this article, she argues that the concept of gender exists because of socialization; that is, society teaches that certain characteristics should be associated with boys while other characteristics should be associated with girls. As aforementioned, in order to demonstrate why society uses gender classifications from birth, Lorber says that people must look at gender as a social institution in that â€Å"gender is one of the major ways that human beings organize their lives† (Lorber, 1994). One of the ways that people allocate others for performing tasks in society, then, is through gender classification. After discussing socialization theory, Lorber goes on to give several examples of how people â€Å"do gender† in today’s society. For example, she discusses how men with baby carriers are stared at approvingly on the bus because these men are seen as changing the role of fathers more towards the domestic end of the spectrum, a role that was previously played only... While Wilder’s characters exhibit traits that help to reinforce the gender norms created by society, Rowling seems to suggest that life is more interesting when these traditional gender roles are bent, just as life is more exciting at Hogwart’s than at the Dursley household. Therefore, in order for males and females to feel comfortable taking advantage of the plethora of opportunities that are available to them, members of society must strive to bend the gender roles that they have assigned.

Immigration history Essay

It was in the early 19th century when immigration of Chinese started in US and the history witnesses both hardship and success for them. In the early years Chinese could get employment as laborers for construction of railroads and in mining industry. But these immigrants had to face the racial discrimination by the local people always. There had been lot of changes in the law of Chinese immigration and there were times when mixed marriages were also banned. There were all kinds of people in society but most of them were against these immigrants as they thought they have come to snatch their job pportunities. Those who were in need of cheap labor favored these immigrants and it was again in 1940s that Chinese immigrants started to come to US. Now the situation is that they are almost 1% of the total population although majority lives the life of middle class there. Most of the Americans treated Chinese as aliens and this discrimination made Chinese live with a distance from them They wore their traditional dress along with the little round hats. Usually these immigrants were poor farmers and in order to work and make money they left their wives and children in China and came to US. They even borrowed money from relatives or moneylenders to pay for the voyage to US. Some of the agencies that needed labors paid for their voyage and that was deducted from their wages later. In this way these immigrants reached US only for the need of a job to fulfill the requirements of their family members. As these were from rural China they faced many kinds of difficulties like language problem, as they didn’t even understand English along with the racial discrimination. The trade relationship of China with New York in the beginning of the nineteenth century rought many Chinese traders in US. The discovery of gold in California caught the main attraction and Wei Long, a small farmer set on a voyage to US. The first thing that came into Wei’s mind was to collect money for his voyage and for this he tried his relatives. Most of them had their own family problems or were already in debt. Lastly Wei had to go to a moneylender and borrow money for his voyage with a promise to repay him as soon as he gets a job. He left his wife with a small child in the village and went to California on the ship that sailed with many more Chinese men. Wei had a dream of aving his own gold mines and become rich as soon as he can. He dreamt of returning back to China with lots of money and solving all the problems in his family. When he reached California, he had to find any kind of work so that to support his living and also thought of saving some for his dream. After peripatetic search for job he got one in Central Pacific Railroad Company. Since the Union Pacific Railroad Company, the chief rival of Central Pacific, was heading fast and prospering, the Central Pacific started hiring Chinese laborers and this is how Wei got a job to carry on. He along with other Chinese laborers were paid quite less than the white laborers but no one had another choice than to accept the most difficult jobs that were offered to them. Wei was quite scared when he first saw the job but with the power of his dream collected and started working. He had to stand in wicker baskets that were lowered with the help of ropes and he had to drill holes in the granite rocks. Then put dynamite in the hole lit the fuse and immediately after this he was lifted up. So many times he thought if there was a few econds of mishandling or late in pulling him up he would have been blown into pieces with the rocks. He had seen many of his fellow workers who either died or lived handicapped. Days and months passed and Wei got employment because Chinese immigrants used to work hard in quite less money and they moved faster than the expectations of their employers. Wei was able to save some money and tried business many times but due to racial discrimination he lost all his money. After trying and loosing his money he thought of just saving some money and go back to his hometown. But this was a difficult task as he immigrants had to face a lot of difficulty to get legal permission for returning back home. However he had started living in Chinatown and was feeling a little bit comfortable with the feeling that he was with his countrymen. It was more than five years and he desperately wanted to go back to his family and his home in Guangdong. He could not buy a house apart from Chinatowns. It was not because there was any kind of law against it but the social discrimination never let him do so. He somehow managed to return back home but he had to sign on papers that he would come back and work for the man who helped him in returning.

Nuclear Energy And Nuclear Power Essay - 1582 Words

Nuclear Energy For many Americans, the electric bill is the most dreaded bill to arrive each month; it is always expensive, yet it doesn’t have to be. To lower electricity costs for citizens and businesses, the Unites States could increase its use of nuclear power. Nuclear energy is created when an unstable radioactive element decays and emits nanoparticles called radiation. With today’s current technology, the emission of these atoms as well as the energy released can be controlled and used in different ways. One such way is in the creation of electricity produced by nuclear power plants. Nuclear power is not renewable; however, it meets every reasonable criterion for sustainability, which is a primary concern for many people. Furthermore, the United States should use nuclear energy as its main source of power for three primary reasons: first, it is the most reliable source of power in the world today. Second, it is more cost effective than any other non-renewable reso urce and, finally, nuclear energy releases no greenhouse gasses, which contribute to global warming. The first reason the United States should use nuclear energy is because it is a reliable source of power due to an abundance of uranium as well as nuclear energy’s independence of climate conditions. Rinkesh Kukreja, author of â€Å"Conserve Energy Future† stresses this when he states, â€Å"As solar and wind energy are dependent upon weather conditions, nuclear power plants have no such constraints and can runShow MoreRelatedNuclear Power And Nuclear Energy Essay1456 Words   |  6 PagesIntroduction Nuclear power is used to some degree to provide electricity to many countries, and it is also playing a significant role as a main fuel resource for marine propulsion for ships.

It has materialized as a somber threat to the dignity of human sexuality and its deific purpose, perplexing the very nature of man and woman and signifying the falsification of mind in the existing age today. It has infested the purity and pureness of sex promoted dilapidation of humanity and advanced the marketization of sex, among other things.

An scrutiny of the†¦show more content†¦And the viewing of women as mere sex objects, rather than a human being, and a complete person. I myself believe that pornography in certain forms can be art, and can be beautiful. A painting from the artist Sandro Botticelli is what I consider pornography that is beautiful. People all over have different views and opinions on this subject of pornography and whether it is morally correct of immorally correct. It is very obvious that some men and some women find pornography pleasurable and find happiness within it. While others believe that it is very unethical to acquire sex for money, and that pornography is hurtful and degrades women. I do however have one question; does anyone out there think that pornography is degradable to men? I believe it is, because not all men view pornography, and not all men that view pornography are violent against women. But when a man is open about his viewing, one automatically thinks that man is capable of rape, or any kind of sexual violence towards women. When looking at pornography from the Deontology theory, which is a no consequentialist ethical theory that claims an act is to be evaluated in terms of its accordance with a specified set of rules. This Deontology theory firmly believes that they have a civil duty to protect women from this type of evil. This theory also says that women are simply used as sexual objects that are being controlled and disrespected. Deontology theory also

Internet and Car Shopping Essay - 951 Words

Internet and Car Shopping Marketing studies show that more than half of Americans who are in the market to buy a new car use the Internet at least once. The Internet has now become part of the process to buying a new car. Most buyers use it to research cars so they save time going lot-to-lot test-driving cars to find that they just dont fit their tastes. Car buyers can research what car publications say about certain cars or just go to the manufactures web site and compare specification to other models. Once you make your decision you can just go down to the dealership or order it online and have it delivered to your house. The best part of buying a car online is not having to deal with the pesky sales men that run out as soon as†¦show more content†¦That is just something buyers cant do at a dealership. I knew a family friend who had a GM credit card for about four years. He had made so many purchases with this card that he built up points that went towards his new car. So when he was ready to buy his new car he went to the GM website and ordered a 2001 Pontiac Firebird with all the options he wanted and desired and in the exact color he liked. The process took about a month to receive his new car but he didnt mind because after he sold his old car and the points from his GM card all he ended up paying was $25,000 for a car that would of normally cost $40,000. Another downside of this process is that you dont have the option of subtracting the sales price with your trade-in because that process is too complicated online where the manufacturer cannot estimate the cost of your old car. So the buyer has to sell his car by himself. But before you can do any of this you first have to apply your credit card to the manufacturer. This could be risky though because of the threat of identity theft. From your credit history buyers can also be financed online. The only setback to this is that the buyer would have to use the manufacturers loan company and wouldnt be able to shop around for the best quotes.
