Why do writers seem to obsess over word count and page count? There are instances when you’re given an assignment, not by word count, but assigned by the number of pages. ” If you need to figure out words per page, you can use a words per page calculator. The writer may be late with the delivery or they may complete a useless paper. If you start looking for the best essay services review, you’ll inevitably encounter Best Essays being recommended as one of the most secure writing agencies. In fact, it probably can be done in 30 minutes or less. The time-consuming part of an essay is the research and how long that takes depends on how much you have to do. But the actual writing of the essay shouldn’t take too long at all. I think an important thing to point out here is that there’s a huge difference between writing a 1000 word essay and writing a good 1000 word essay. You can write an essay in hardly any time at all if you don’t do the proper research and don’t spend time editing what you wrote. Put your thesis statement in your first paragraph then make sure you refer to it several times within the essay then restate it in your conclusion.

You should always give yourself more time than you think you’re going to need to get it done. If you already have all the research done and know what you want to say, then a 1000 word essay shouldn’t take more than an hour to write. The reason that teachers don’t assign a number of pages anymore is because it’s too easy to manipulate pages. When students used to write on typewriters, it was common for teachers to assign essays in number of pages. With the adoption of computers in the classroom, teachers switched from pages to work count because it was too easy for the computers to manipulate the font size and page size. By assigning a word count, teachers get a more accurate length of essay than they would if they assigned homework by pages. If the customer is not satisfied, we have a money back guarantee. We have over 450 dedicated essay writers who will happily write your essay even with 3 hrs. Well, there are no specific types of service available. However, taking into consideration the specifics of this service, I can say that it may somewhat help you with your essay. I would not recommend using it for any other serious assignments and probably not even for essays. You already have a topic and the paper outline it is time to start the writing. Begin by creating a thesis statement which must tell your reader the purpose of your essay. Read through your outline to help you create an appropriate thesis. Your thesis statement must state the topic and the main argument of your essay. The single statement must carry the overall response to the problem.

Are Sharks as Dangerous, as People Consider Them to Be

Are Sharks as Dangerous, as People Consider Them to Be? Among the richness of the animal world and the exciting images it offers fishes have never arrested too great an attention of human beings. Though, there are a lot of books, films and other media on virtually any kind of mammals, birds or lizards. There is hardly anything to be found being dedicated to fishes. With one exception, nevertheless. The exception is sharks, especially – the great white shark or Carcharodon Carcharias. It is hard to imagine some other predator that inspires so much terror and disgust in humans, along with a kind of morbid fascination. The very image of its triangular fin gliding above the water imposes a kind of primeval terror upon people, being the embodiment of the ancient fear of being devoured alive by something alien and unfamiliar, coming from the uncharted depths of the sea. However, most of this fear may easily be tracked down to much more contemporary times, than some kind of genetic memory. We speak, of course, about a bestselling Peter Benchley’s novel Jaws and its many film adaptations, spin-offs and imitations. The book about white sharks attacking, maiming and eating humans turned out to be a great success and actually created the image of a shark as a man-eater in the mass culture. The facts, however, testify rather differently. Although there was a number of documented shark attacks on people, their number is far less than one could have supposed taking their reputation into account, with only a small percentage of them being fatal. It seems that white sharks don’t like the taste of human flesh, or at least find it unfamiliar. As their only way of interacting with the outer world is biting, they often test-bite unfamiliar objects, including humans, but generally leave them alone afterwards, discovering that they are very unlike their usual food.

Feminism And The Feminist Movement - 1110 Words

William Fayson English 1102 Professor Williams I Spy Feminism In today’s society if we asked people the first thing that came to their mind when they heard the word equality, my bet is that not many of them would say something along the lines of male versus female. Females before, during, and after the feminist movement have been subject to discrimination because of what doesn’t lie in between their legs. Females are often steered away from the things they enjoy doing simply because it may seem too masculine. Women in the past usually worked the positions of teachers or nurses, simply because that was seen as one of the jobs of the women. The feminist movement began because; during the time the world for women was strictly bound to the household. Taking care of children and feeding the man when he returned home for work was to be expected of these women. However, many people don’t fully understand the extent of what feminism is. Feminism involves a personal commitment that fights for the equal rights o f females and males politically, socially, and economically. AND feminism fights to end discrimination in all aspects of life. Don’t get me wrong, feminism does so much that it can cause people to come up with different depictions of what it is.

Pros And Cons Of Animal Cloning - 1277 Words

Animal Cloning Applications and Morality Concerns One fateful afternoon, a father discovers that their beloved pet kitten is deceased on the side of the roadway. The parents are worried about telling their children the sad news because they will be devastated. Luckily, the parents reach out to a company that offers animal cloning. With just a sample of the kitten’s DNA, they can produce an exact match and an identical copy that will soon replace their lost family pet. While this story demonstrates one practical use of animal cloning, there are many other reasons why animal cloning is beneficial. Larisa Rudenko, Ph.D., states that clones are genetic copies of an animal, similar to identical twins that are born at different times†¦show more content†¦This is not the only example of why cloning transgenic animals is important. Transgenic animals can also be used to produce pharmaceuticals, nutraceuticals, and xenotransplant organs that can be used in humans (Smith 4). There are hundreds of thousands of people waiti ng for an organ transplant in the United States. If more transgenic animals were created, the dependency on human donors would be reduced. Another benefit of cloning is that extinct or endangered species could be brought back to past populations levels. For example, dinosaurs could be revived. According to Genetics Science Learning Center at the University of Utah, all scientists would need is â€Å"a well-preserved source of DNA from the extinct dinosaur, and a closely related species, currently living, that could serve as an egg donor and surrogate mother† ((((Why Clone Article citation). The movie Jurassic Park could become a reality. Zoos could be filled with previously-extinct species, never seen before. Although the science is not perfect, scientists have already tried to bring an extinct goat back to existence.

Research Essay Youth - Identity and Digital Media

Question: Write about theResearch Essayfor Youth, Identity and Digital Media. Answer: Introduction This study is based on the difference between the use of mobile phone in public space and in private space and its negative impact. The use of mobile phone has injected itself into the public places. Due to this the line between the public and private space has been blurred out. Now days the common part of background noise during picnics, bus rides, sidewalk strolls, grocery shopping excursions, waits in airport terminals and other venues. To note the response of these changes, views of different people were asked regarding general mobile phone etiquette in public. In this process around 10 people were interviewed to identify the difference between the use of cell phone in public and in private space and to know the disadvantages of excessive use of mobile phone. Different questions were asked to support the survey. Research Questions How can Purchase of Mobile Phone be Affected? We all know that cell phones have diverse use according to their necessities. The usage of mobile phone has taken a sudden increase in recent years, various factors are considered while taking decision of purchasing a new cell phone (Don 2008). The result of the survey showed that the important factors that influence purchases are pricing, size and weight, charging and operating facilities, recommendations from friends and colleagues, recommendation from neighbours and through advertising (Sherry 2011). How has the Concept of Friendship been Altered by Social Media? Yes, it is true that the concept of friendship has been changed due to the influence of social media. People start thinking their social media friends to be their true friends and forget the value of real life friends (Richard 2010). They have forgotten the rules of friendship. It is said that social media is that type of new platform which facilitates communication expansion and accelerates the process to connect and engage different people. To make real friends, one should always know the person well, and also develops and understanding regarding the likes and dislikes of that person. It is not the fault of social media but the blame is put to the wide net of connections (David 2008). Social media is responsible to change the ways of interaction, but still the rooted norms remains unaffected. Adjustments should be done to build relationships in the new phase of platform. What are the Consequences of Excessive use of Mobile Phones in Public Space? During the survey it was found out that excessive use of cell phones is responsible to kill face-to-face interactions between people (Glaser 2007). It is unfortunate to know that the real life interactions are considered to be less effective and more time is given to solve the issues by making discussions on cell phones through conversations, instant messaging, and texting and through face book mails. This happens especially in case of young people. How do Mobile Phone users Engage in Developing their Personality Online and in What ways it Reflects the Reality? When an individual engages in developing his/her personality online, the understanding and formation of own identity gets highly affected. The main purpose of this research is to bring into notice the effects of excessive use of social media and its influence (Nicholas, 2010). Youth forgets the value of real life and real relationships and simply keeps their focus on how to make their personality strong online to attract more people and make more friends. Sample and Methodology This study was conducted to know the degree of influence that the use of mobile phone can bring. Around ten interviews were conducted. The main focus was to target the youth of Singapore to know their habits and criteria for excessive use of cell phones in public (Ritter, Gordon and Elizabeth 2014). Not only youth but people between the age group of 30-50 were also contacted to know their opinion towards the use of mobile phone and its influence in the real life. Direct interview was conducted and their opinions were noted down so that a clear conclusion can be dropped in this report. Data were collected from different people in Singapore maintaining equal ratios in relation to female, male employees, students and businessmen. Findings and Analysis From the above research study it is clear that in recent years the usage of mobile phones has increased a lot and it is affecting badly the real life of the youth. The use of mobile phone in middle of a conversation when two or more people are talking gives a negative impression. (Lizette 2013). The frequent use of mobile phone can bring negative effects to the health of the user. Constant ringing, reminders and vibrations can put a user on edge. It can also cause risk of illness in the users immune system (Ling, Wonil and Gavriel 2007). The oily residue or greasy substance on the mobile phone can cause severe disease as it contains disease prone germs (Thome, Annika and Mats 2011). Staring at the screen of cell phone constantly can cause vision problem as well. Conclusion We can conclude by saying that mobile phones have changed our world. People start using their phone in leisure hours, business, school, etc. People rely on them for many things, such as, conference calls, video calls, etc. There is no doubt that emergence of advanced features in mobile phone has bought many technological advancements but we cannot ignore the fact that is its bringing negative impact in the real life of the users. The users should limit the use of cell phones to ensure a healthy life. From the research conducted it was developed that youth makes more usage of mobile phones and they should know its negative impact that could be dangerous to their life, career and future. The use of mobile phone should be banned in public places to create a sense of comfort and healthy environment for all to survive. References David, Buckingham. (2008).

(b) A drum with negligible mass, 0. 4m in diameter, is attached to the motor shaft, and the power output of the motor is used to raise a weight hanging from a rope wrapped around the drum. How heavy a weight can the motor lift at constant speed? c) At what constant speed will the weight raise? The outstretched hands and arms of a figure skater preparing for a spin can be considered a slender rod providing about an axis through its center. His hands and arms can be combined mass 08kg. When outstretched, they span 1. 8m; when wrapped they form a cylinder of radius 25cm. .u6a702cab01b9fd33a271db54e70f33e4 , .u6a702cab01b9fd33a271db54e70f33e4 .postImageUrl , .u6a702cab01b9fd33a271db54e70f33e4 .centered-text-area { min-height: 80px; position: relative; } .u6a702cab01b9fd33a271db54e70f33e4 , .u6a702cab01b9fd33a271db54e70f33e4:hover , .u6a702cab01b9fd33a271db54e70f33e4:visited , .u6a702cab01b9fd33a271db54e70f33e4:active { border:0!important; } .u6a702cab01b9fd33a271db54e70f33e4 .clearfix:after { content: ""; display: table; clear: both; } .u6a702cab01b9fd33a271db54e70f33e4 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u6a702cab01b9fd33a271db54e70f33e4:active , .u6a702cab01b9fd33a271db54e70f33e4:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u6a702cab01b9fd33a271db54e70f33e4 .centered-text-area { width: 100%; position: relative ; } .u6a702cab01b9fd33a271db54e70f33e4 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u6a702cab01b9fd33a271db54e70f33e4 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u6a702cab01b9fd33a271db54e70f33e4 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u6a702cab01b9fd33a271db54e70f33e4:hover .ctaButton { background-color: #34495E!important; } .u6a702cab01b9fd33a271db54e70f33e4 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u6a702cab01b9fd33a271db54e70f33e4 .u6a702cab01b9fd33a271db54e70f33e4-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u6a702cab01b9fd33a271db54e70f33e4:after { content: ""; display: block; clear: both; } READ: Saint John Bosco Essay Research Paper The movement of inertia about the rotation of axis of the remainder of his body is constant and equal to 0. 40kg†¢m2. If his original angular speed is 0. 4 rev/s, what is his final angular speed? pic] A large wooden turntable in the shape of a flat uniform disk has a radius of 2m and a total mass of 120kg. The turntable is initially rotating at 3 rad/s about a vertical axis through its center. Suddenly, a 70 kg parachutist makes a soft landing on the turntable at a point near the outer edge. (a) Find the angular speed of the turntable after the parachutist as a particle. (b) Compute the kinetic energy of the system before and after the parachutist lands. Why these kinetic energies are not equal?
