We will write a custom essay sample specifically for you Proceed Communication Internet is the ultimate and the inevitable tool for communication and the meeting of people. Through the means of chatting and other instant messaging services as well as the use of the email system that includes the yahoo, msn, AOL and gmail and others. It allows people to make and maintain contacts with acquaintances and friends and also a means and an important way to form new friendships and contacts. The internet, therefore, is seen as a socialising tool by many. Apart from the instant messaging services and all, the internet now offers a variety of options in terms of social networking. Its a new phenomenon in the world of internet and has the ability to take the internet and the social world by storm and it has already done so to a large extent. The introduction of websites like orkut, multiply and hi five and the others of the same ilk has given life a new meaning. People now make friends on internet and talk to them there too. Social life has been limited to the internet. Online Earning Another means of internet usage is the availability and opportunities of earning online. People are now able to make money through online jobs such as the freelance writing and writing content for websites. Apart from the above-mentioned opportunities there are students that could be taught online and other such opportunities that are taken up by people due to the easy money they offer and the convenience that is present in the form of earning from home. Blogging and Social Activism and Expression Another present phenomenon is that of blogging. Blogs are personal diaries in which people can talk about any and everything. They could be based on a particular theme, for example, sports or could be general. Blogging is another reason why people are badly addicted and hooked onto the internet. It allows one to express oneself freely and thus, is highly popular amongst masses especially youth. Its important because its free and most people are devoid of an outlet to express their feelings and ideas. Social activism is another aspect of internet. Through blogs and websites such as CHOWK that allow interaction and discussion of ideas and serious political talk and analysis, its now possible to campaign for causes one feels passionate about. All the above-mentioned causes become great motivators for people to become addicted to the internet. But as any addiction has its accompanying disadvantages, so is the case with the internet. Internet addiction has been a cause of grave concern with sociologists, teachers, and social analysts and most importantly with parents. The excessive use of internet is likely to result in the loss of concentration and also inflicts some negative consequences also on the health like poor eyesight and back pains. Besides if children and/or teenagers are exposed to the kind of content on the internet that is not suitable and reasonable for their age, grave moral and social consequences shall follow. Children are said to become violent and have destructive tendencies if they are exposed to violent images and graphics which are rampant and abundant on the internet. Same is the case with the wide and easy availability of sexual images and content on the internet that are said to wreak havoc on the behavioural patterns and psychology of the children and young adults in the advices and opinions of the psychologists and psychiatrists and even cause destructive sexual tendencies in them. Reasons of Spread of Internet The changing societal set-up has given rise to the idea of internet addiction. The present times are such that everyone has multiple duties to perform. There is a dearth of time and people find it hard to juggle successfully their personal and professional lives. All of the hectic schedules leave little room and time for other activities of life such as socialising. Internet thus replaces real-life interaction because it is convenient and one does not have to make any special efforts to talk to people. On the other hand, the cost options are much better. Internet interaction and communication is free to a great extent. Its an awesome way to connect to people that live abroad and are hard to talk to in other ways. Besides internet is a great way to collect and gather information. Internet possesses great loads of information about almost all topics which is almost a click away in many cases or requires extremely little effort in comparison to other sources like books and libraries. It is also cost-effective and the existence of search engines such google and yahoo facilitates matters a great deal. All sorts of information is available that mainly helps and aids the students and scholars alike in their assignments and studies and in the ever-lasting pursuit and quest of information. Many leading universities of the world like Oxford, Cambridge and Princeton have their online libraries that have information and books that were otherwise present only in the libraries of their colleges and university campuses. Similarly many public libraries too have their online portals making it easier for students to manage their workload easily. There are numerous earning opportunities also available online and through outsourcing. it gets cheaper for the international companies due to costs and other benefits. The lifestyle coupled with the advantages of internet makes it into an addiction. Many are concerned because of that but there is cause not to as internet is a tool for useful interaction of ideas and has much to offer by way of academic knowledge. There are also e-books available online and that enhances internet utility. There are zillions of books available online free for both academic and non-academic topics. This greatly attracts and allures the students as well as the casual and occasional reader. Internet is an inevitable tool for communication and entertainment and slowly, it is turning into a force that cant be controlled.

Cells Cell Essay Example

Cells Cell Essay Example Cells Cell Essay Cells Cell Essay Cells Cells Cell division and cancer Victoria Brothwell Strayer University Cells Introduction Regular cells and cancel cells are extremely different. Depending on the cancer that one may have cancer cells have more chromosomes that are scattered which is for why cancer cells are formed. In cell division all living things obtain cells in which come from other preexisting cells. If normal cells are do not divide and make new cells then cancer will occur. In order of all cells to be the same as a parent the mitosis in a must. Mitosis is the separation of copied chromosomes into single cells. The problem with unregulated cell division is that most of the time this will lead to cancer. Only when DNA replication as well as mitosis is working the correct way then cell cycle cell points are insured. Cells Methods Cell division occurs when cells are dividing in order to produce new cells. I have compared the differences between cancer and good cell division to find out the process of division of all cells, this is also when I found that there are different more complicated chromosomes in cancer cells. One of the main problems with cancer cells comparing is the chance of tumor formation which leads to the invasion of cancerous cells. Another consequence is the cancer spreading to other organs. A tumor consists of a mass of cancer cells in the tissue. Usually an evasive tumor is malignant, causing cells to develop in the blood. Tumors invade growth that the tissue and organs need to survive.

Based on your data and observations, what are some of the Differences between normal cells and cancer cells? With normal cells I have noticed that the chromosomes are more still that scattered, Cancer cells chromosomes are dividing and scattered a lot more. 2. Which type of cancer shows the most aggressive growth? Explain. I would have to say that cancerous ovary’s are more aggressive it has more scattered chromosomes being with the least still. 3. When studying cell division in tissue samples, scientists often calculate a mitotic index, which is the ratio of dividing cells to the total number of cells in the sample. Scientists often calculate the mitotic index to compare the growth rates of different types of tissue. Which type of tissue would have a higher mitotic index, normal tissue or cancerous tissue? Explain. Cancer cells you have more calculations with different cells in cancer. Cells Conclusion My conclusion is supported by my hypothesis even though I am talking more about tumor cancer I am explaining the difference about normal and cancerous cells. The differences is cells division is when they go according to plan they divide and create new cells and when they do not create new cells and divide it can cause cancer. The cancer cells have chromosomes scattered while normal cells have more still chromosomes that are dividing.
