Find out Why a Goldfish Turns White If Left in the Dark

Find out Why a Goldfish Turns White If Left in the Dark The short answer to this question is probably not white, though the color will become much paler. Goldfish Can Change Colors Goldfish and many other animals change color in response to light levels. Pigment production in response to light is something were all familiar with  since this is the basis for a suntan. Fish have cells called chromatophores that produce the pigments that give coloration or reflect light. The color of a fish is determined in part by which pigments are in the cells (there are several colors), how many pigment molecules there are, and whether the pigment is clustered inside the cell or is distributed throughout the cytoplasm. Why Do They Change Color? If your goldfish is kept in the dark at night, you may notice it appears a little paler when you turn on the lights in the morning. Goldfish kept indoors without full-spectrum lighting are also less-brightly colored than fish exposed to natural sunlight or artificial lighting that includes ultraviolet light (UVA and UVB). If you keep your fish in the dark all the time, the chromatophores wont produce more pigment, so the fishs color will start to fade as the chromatophores that already have color naturally die, while the new cells arent stimulated to produce pigment. However, your goldfish wont become white if you keep it in the dark because fish also get some of their coloration from the foods they eat. Shrimp, spirulina, and fish meal naturally contain pigments called carotenoids. Also, many fish foods contain canthaxanthin, a pigment added for the purpose of enhancing fish color.

Objectivism and Collectivism Essay Example | Topics and Well Written Essays - 500 words

Objectivism and Collectivism - Essay Example This has brought about the two philosophies of collectivism and objectivism which can be said to be direct opposites of one another when it comes to the beliefs and practices they promote (Mayhew 56). They do however also maintain a few similarities in certain aspects as well and it is by comparing and contrasting that one is able to identify both the differences and similarities that objectivism and collectivism bring to the table in the discussion of a life well lived. One platform that exhibits both these philosophies clearly is in the book (Mayhew 26) Anthem written by author Ayn Rand in the year 1937 though it was published a year later. In this book the author manages to depict the two philosophies in various scenarios and through various characters within the story that can help one compare the two. It is suggested as a matter of fact that Ayn Rand was the individual who came up with the philosophy of Objectivism so it is no surprise that it is displayed phenomenally in this p iece of literature (Mayhew 154). Objectivism refers to a philosophy that advocates that the purpose of an individual’s life is the discovery of their own happiness and thus morality is achieved in the respect of one’s individual’s rights. Objectivism promotes putting one’s self interest ahead of the pack and the author Ayn Rand describes it as "a philosophy for living on earth" that defines human and worldly nature and thus can be said is established in reality (Mayhew 235).

Businesses additionally are run in a systematic manner, involve various processes, and have a number of rules and regulations that must be followed by those involved in it. One can observe additionally a number of departments in every business that manages various activities, such as the marketing department, finance department, promotion and advertising department, customer care department, etc (Nolan, pp. 20-39). A number of external and internal factors, which may include inflation rates, interest rates, and the exchange rate of a country’s currency can also influence every business and various skills are required in order to run a business smoothly and successfully along w ith achieving its objectives. Recently, due to the earthquake in Japan, which was followed by a tsunami, many changes have occurred in a number of businesses in the country. In an article by Alex Taylor (2011), found on the CNN website, the author (Taylor, 2011) talks about how Japan’s auto making industry is down but not out. He states that the two natural disasters that recently occurred will surely cause various shortages in the industry, but as noted before, Japanese automakers have the power to find their way out of catastrophes successfully. The author (Taylor, 2011) further states in his article that a Toyota representative had reported that no deaths or injuries have been under notice in the Toyota parts plants and subsidiaries, but the plants have surely suffered damage. According to Alex (Taylor, 2011), Toyota plans to keep its 12 main assembly plants in the country closed until Tuesday and the company’s representative stated that this might cause Toyota to l ose 95,000 units of cars that could have been under production. Due to this, Toyota reduced acceleration of the process of production in North America in order to conserve parts (Gholz, pp. 26-30). Japan’s auto making industry (Shimokawa, pp. 56-64) is currently trying to recover and resist from coming to an end, while people in the country are busy burying the dead, rescuing and curing the living citizens and dealing with the aftermath of the great disaster. Korea’s Tong Yang Securities states that production in the industry will surely not be able to come back to normal very soon, even though security analysts are quite busy doing their job and evaluating the results of the major catastrophe. Statistics (Taylor, 2011) included in the report show that in six months after the earthquake that occurred in January 1995, â€Å"shares of Toyota, Honda, and Nissan dropped by 22%, 35%, and 40% respectively† (Taylor, 2011), and it took the companies around one month abo ve a year to recover from the massive destruction and loss caused by the earthquake. At that time, Honda and Mazda, both halted the production of their vehicles and parts for the rest of the week after the disaster, and there was a loss of production of about 36,700 vehicles a day (Taylor, 2011) globally. The author of the article (Taylor, 2011) fu

Strategic management Essay Example | Topics and Well Written Essays - 750 words

Strategic management - Essay Example Thus, it has become imperative for airliners to re-engineer their operations to fit the requirements of strategies like low-cost and differentiation. According to the Porter’s five forces model, the industry situation has led to a decline in the attractiveness of the industry for new entrants. These new entrants would come up with some sort of an edge to beat the entrenched airlines of the industry. The industry is also overseeing a period in which the bargaining power of suppliers and customers both are high. Customers are demanding additional benefits at low cost, whereas suppliers like Oil companies are seeking high prices for fuel. The dynamics of the industry are such that the rivalry amongst competitors is high. Since the customer base has shrink as a result of the world recession, therefore airlines are competing to attract customers towards them by offering differentiated services. Moreover, recent investment by the government on the infrastructure of railways and road network has lead to a situation in which threat of substitute is high for this industry. The results of these two strategic analysis tools show that the airline industry is overseeing a period of unprecedented level of competition and operating environment. Therefore, each airliner needs to come up with operational excellence that allows it to run low cost operations, which has become imperative for the industry participants. How the Airlines are maintaining low cost operations: Airlines, which have adopted a low cost operational mode, have been very stringent when it comes to spending their resources. They have expanded their operations in to new regions only when they were confident that they had the resource to support this initiative. These carriers never go into a head-to-head battle with long distance carriers. Moreover, these airlines try to keep their debt position very strong by not taking too much debt to fund their fleet operations. These airlines have designed an operat ional method that allows them to be short haul, high frequency, and low fare and point-point carriers. In addition, these air carriers have identified a market niche that is a best fit to their style of operations, which enables these airlines to serve them efficiently and economically. Most importantly, these airlines have ripped away the costs associated with extravagant customer servicing. Such costs are associated with frills, lunch and ticketing material. All such costs have been taken away from the operations of these airlines. Conclusion: Harsh economic conditions coupled by rising cost of fuel have made it imperative upon airlines to streamline their operations. Airlines have to come up with a cost structure that is effective and efficient. This cost structure should be incorporated in the operational design of these airlines so that the airline can generate profits from its operations. In this regards many airlines have adopted a low cost strategy under which they have take n certain actions that have been discussed above. Strategic Evaluation of the Strategic Options for Future Growth for the EAI Companies: Recent economic crisis have led airliners in a messy situation. These airliners are now facing a situation in which they have revenues declining at an exponential rate. Moreover,

How Do Single Sex Schools Effect Students Young People Essay

How Do Single Sex Schools Effect Students Young People Essay Single sex school is better than co-ed school as it brings more confidence to every individual. Single sex education as known as single-gender education, is the practice of conducting education where male and female students attend separate classes or schools while co-ed school is the integrated education of males and females in the same institution. Socially, single sex school makes for more mature people earlier. Young people learn more from experience of diversity. Educationally, single sex schools seem to be better for girls to do well at traditionally male subjects like chemistry and physics. Emotionally it encourages sexual relationships which some say its a distraction from education or is to be objected to morally especially for girls which is why Islam forbids coeducation. If a boy isnt male stereotype in personality he is more likely to be lonely in a single-sex school because with co-ed he may find girls to hang out with. Generally single-sex schools tend to have better academic grades and better discipline, but this may be because most of the hard-working Hindu and Muslim children go there or for other reason that allow them to select against disruptive and disaffected kids, rather than because they are single-sex. Furthermore, single sex schools are more educational than co-ed school because boys are less attracted by girls and girls are also less obsessed with the boys. Therefore, students may pay more attention on classes while all students are same sex. Besides, they will also break out of their behavior when they are left to their own devices. Single sex education has a delightful way of encouraging students to be fearless, to be curious, to be enthusiastic, and to just be themselves. Single sex education with more controlled social outlets is just the ticket for many students. Firstly is less pressure to act cool around friends of other sex. Secondly is less conflict between friends of the opposite sex. Thirdly is more relaxed attitude such as not putting on a show for boys or girls they like. Last but not least, they have lower levels of anxiety over appearance or clothing. Also, less emotional stress brought on by the head games teens play while in relationships. There are several reasons for choosing a single sex school. For boys, they tend to soften their competitive edge and become more cooperative in a single sex school. They can just be boys and not worry about what girls might think or judge them. Furthermore, boys enjoy playing in an orchestra as opposed to a marching band and learn Latin in single sex settings. For girls, teachers will quickly feel comfortable exploring non-traditional subjects like mathematics, advanced science, computers, and technology if the teacher understands how to teach girls. Besides, they may drop their shyness in a single sex setting. They join some sports like hockey, football follow their hobbies without worrying about appearing like tom boys girls are free from sexual harassment which always happens in co-ed high schools. In all-girls schools, girls take over all the positions of leadership whether its drama, sports, or debate team. Also, they participate in class discussions freely, which boys always dominate in co-educational schools. They tend to gain confidence in themselves as students and score higher on their examinations. Girls no longer have to live up to expectations that they must be nice, quiet, non-athletic, and passive. Moreover, girls may work harder without boys distracting them. Girls brains usually work differently from boys because girls are more likely to take up subjects normally dominated by boys. For example like maths and sciences. On the other hand, co-ed schools are many like gender stereotyping has mostly seen in these institutes. Both sexes are almost immature in the very young age and they get mix and are not able to keep a distance. Teacher favoritism is also major issues like some teachers favor girls and some boys. It has been observed that Co-education can cause gender stereotyping. Many students are not able to focus on their studies and they become interested in each other at very young age. Some favoritism has also been observed. In co-education sometimes it becomes difficult for the parents to manage their kids. Students are more likely to become fashion conscious. It can affect the natural learning for some of the students. Co-Education is bad because it create the complex in the poor student who cannot afford expensive mobiles, car, motorbike  etc. The one big disadvantage about having boys and girls in the same class is when we go for physical education. Boys and girls just cannot do the same type of exercise or play the same game together. So we need to have two teachers, one for the boys and one for the girls. Our headmaster has come up with the ingenious solution of having two classes doing P.E. at the same time so that the boys and girls from each class combine together under one teacher each. There are certain conservative people criticize the system of co-education. According to them, this system is against our tradition. They also fear that co-education will develop immoral relationships between boys and girls. They believe that in this system both the boys and girls will be spoilt. The negative aspect is engaging in some non required activities like mostly in coeducation girls and boys are found hanging around those cafes and pubs bunking the classes and this all stinks There are also certain disadvantages of co-education. First, co-education is against the law of nature. Girls and boys are temperamentally different from each other. They have different duties to perform. A girl is required to receive education which can make her a good wife and a good mother while a boy is required to receive education which can make him a good husband and a good father. A Uniform education cannot help them be expert in their respective fields. Thus the very idea of co-education is wrong. Then co-education is against our traditions. It will develop immoral relations between boys and girls. Young boys and girls may fall a victim to their emotions. Moreover, research on coeducation has shown that coeducation in its commonly practiced form tends to reinforce rather than diminish gender stereotypes. For several years the studies concentrated on girls, only during the last seven years or so the focus shifted to boys. All in all, it can be said that coeducation has proved to be of great disadvantage for both sexes. Some of the most common disadvantages for girls are having less space at their disposal, literally as well as symbolically speaking in coeducational classes. Furthermore, no matter if the teachers are male or female, girls get only few fraction of the teachers attention compared to boys. Also girls are abused as social workers, according to the motto seat a well-behaved girl next to a disruptive boy, so as to create an orderly working situation in the classroom. Girls achievements in school are discriminatingly attributed to their diligence versus boys intelligence. Disruptive girls are treated much more severely than d isruptive boys. Boys are given more speaking time during lessons. Cooperative behavior of girls is labeled as conformity, whereas boys` competitive attitudes are usually admired and seen positively by teachers. Girls` contributions in lessons are often pulled to pieces by their male classmates. They are also humiliated, degraded and ridiculed. Even today girls are little motivated for science and mathematics and still opt for traditional female subjects like languages and humanities. The same applies to the choice of schools girl tend to attend schools that are traditionally associated with female education and shun technical schools. Girls` strengths are often not seen as such: cooperative behaviour, high commitment in school, social intelligence, high achievements, good performances, to name but a few. During the early years of research on gender and school ( from the late seventies onward), most of the studies dealt with girls. Programmers to strengthen girls were developed and practised. As a result not only of this , but also of the crisis of the male in Western world in general boys seem to have become even more disruptive and difficult. And so it was realized that coeducation cannot be improved without working with both sexes. As a result the focus of researchers to a very high degree female turned to boys, particularly boys up to the age of 14 or 15. Also, there was a change as to the approach: In the early days of gender conscious work in schools (notably with girls), girls were seen as having deficits compared to boys. From the late eighties onwards the approach was that of a concept of difference, with the vision of a school in in that offered equal opportunities for both boys and girls, reinforcing non-traditional gender stereotypes rather than perpetuating the traditi onal ones. Besides, the disadvantages of coeducation for boys are most of the boys have great problems in the field of social competence. Cooperative methods of work are difficult for them (group and teamwork, for example) whereas, vice versa, girls find competitive methods more difficult. Boys tend to solve conflicts with physical and verbal aggressions. They lag behind considerably in language learning, achieving far worse results. In general, male pupils have worse results in school, fail more often and have a higher dropout rate. As a conclusion the advantages and disadvantages of attending a single sex school or co-educational school are now being looked into more closely when the decision is being made on which environment is best for a child to learn. Each school environment has pros and cons to offer the student. What is important is that the right learning environment is selected based on the one student and how they learn. When a student is not placed in the right learning environment for them they can begin to fall behind the rest of the class. It is important to keep in mind that neither learning environment has yet to show that is the best learning environment for all children to be taught in. This is why the question Is a single sex school or a mixed school the best learning environment for my child? is been asked more and more recently but as a advantage they would able to know how to behave and the difference between them.

The Internet Does Not Equal Isolation Essay -- Internet

The Internet Does Not Equal Isolation The computer has become a centerpiece for almost everyone’s lives. Teachers require homework to be typed, and students go through an Internet search tutorial at the beginning of every year. Communication online plays a role for many people with the introduction of instant messaging, message boards and chat rooms. Even businesses run their companies on computers and sell online. This can bring up controversy. Some believe that the Internet isolates people and takes away face-to-face interaction. Some studies have been done to see if the Internet causes loneliness. Does this mean that all Internet activity does harm to the world? No, in fact, it can do quite the opposite when actual contact is impossible. Internet has the potential to save lives, connect families and friends, and give ill patients a support system. Internet provides exceptional resources for health information, in particular transplants and organ donations. The web provides a great opportunity to share a wealth of information, and informing people about diseases and providing resources helps a lot in patients’ understanding. For example, TransWeb (www.transweb.org) provides a great amount of information on organ transplants and donations. On this site, the latest news, stories and conference information can be found.

Isolation in “Lord of the Flies” and “Heart of Darkness” Essay

This is an awsome essay! Feel free to use it. Great comparison of books, excellent work. novels. Throughout Lord of the Flies and Heart of Darkness the importance of restraint is greatly stressed. This being the restraint to remain human and maintain sanity. In Heart of Darkness, Marlow was able to remain his restriant despite how difficult it was for him. He was always surrounded by cannibals and constant chaos. On the other hand, Kurtz was unable to keep his restriant, as a result he lost his humanity and sanity, and eventually died because of it. In Lord of the Flies, Ralph is able to restrain restrain, and he therefore remains human. He found it difficult though, because there was only one other person who was able to do the same- Piggy. Ralph was determined to maintain order, and he was very alone because of it. Jack on the other hand, gave in to the temptationof simply hunting and playing, and lost his humanity in the process. He became a savage – not a human being, but a savage with a painted body and strange barbaric ways. In contrast, the cannibals in Heart of Darkness, (who are starving) could have easily had many satisfying meals. After all, they outnumbered the whites thirty to five, but they still had necessary restraint to refrain from savagely feasting on some of the easily accessible seamen. Towards the end of the novel, Marlow becomes becomes very close to losing his sanity, but also has the necessary restraint to maintain it. He confuses the beat of a drum (the call to man’s primative side) with his own heartbeat, but is still able to restrain from slipping over the edge as Kurt did. Ralph in Lord of the Flies is constantly faced with temptation to join Jack and all of the other boys, especially when Piggy dies and he is all alone. This makes it even more difficult to restrain from giving in to Jack and his animalistic tribe. Therefore, it is evident how important restrain is in t hese two novels. The ability to do so may be the difference between life and death, and the one who can restrain himself teh most is the one who prevails in the end. In conclusion, it is evident that the authors of these two novels wrote about their own life experiences because they were able to draw emotion form things that actually haopened to them. Also, through Lord of the Flies and Heart of Darkness, Golding and Conrad were able to express the isolation that some of the characters were forced to endure, and the importance of restraint in dealing with one’s humanity. These compelling novels leave the reader with two possible questions. Would I be able to cope with the intense isolation? And, do I have the necessary restriant to maintain the humanity which so many people take for granted? finally, the reader would be left with a better understanding of the darkness, which Golding and Conrad believed, each and every one of us possess somewhere, deep down inside.
