Writing an Argumentative Essay

Writing an Argumentative EssayWriting an argumentative essay can be very difficult to some students, especially those who are not used to writing essays. They tend to believe that writing an argumentative essay involves a complex planning process. In fact, they have to remember and do the very same things they did in the writing of an objective essay. You can help them understand by reading through the following instructions.First, you need to learn how to write the verb tense in all the present tenses. The verb tense is one of the most important parts of a thesis. It is the element which determines how sentences and paragraphs would flow. For example, if you were writing a thesis on the workings of the North Korean army, you would not only use verb tenses like the past tense and the present tense but also tense verbs. You would be using the current tense.In the case studies, you need to show the various parts of your thesis. The first chapter in an argumentative essay outlines the w hole thesis, so the chapter title should be 'Chapter 1' and the first paragraph on the next page should be 'Chapter 1: The First Chapter'.Another reason why many writers muddle up their writing is because they are not sure where to start. Do not worry, you do not have to complete the first few sentences with one kind of sentence, no matter how easy it is. Start the thesis with an action verb, such as 'to go'to write'. Continue by making sentences with two action verbs. From there, you can link each new sentence to the previous one by using the very same verbs.You should also begin by describing the chapter you are going to write in terms of the main ideas of that chapter. And then, you will need to use the same grammar rules for all chapters of the thesis.Do not forget to include in your argumentative essay outline the three subsections which you want to focus on, as well as the other details of the section. You should even include the sentence structure, style, and style of all the pages.Your thesis is your chance to share your thoughts on a particular topic with others. You should use it to showcase your research and knowledge about that topic, while also presenting the importance of your work.

Bacterial Reproduction and Binary Fission

Bacteria are prokaryotic organisms that reproduce asexually. Bacterial reproduction most commonly occurs by a kind of cell division called binary fission. Binary fission involves the division of a single cell, which results in the formation of two cells that are genetically identical. In order to grasp the process of binary fission, it is helpful to understand bacterial cell structure. Key Takeaways Binary fission is the process by which a single cell divides to form two cells that are genetically identical to one another.There are three common bacterial cell shapes: rod-shaped, spherical, and spiral.Common bacterial cell components include: a cell wall, a cellular membrane, the cytoplasm, flagella, a nucleoid region, plasmids as well as ribosomes.Binary fission as a means of reproduction has a number of benefits, chief among them is the ability to reproduce in high numbers at a very rapid rate. Since binary fission produces identical cells, bacteria can become more genetically varied through recombination, which involves the transfer of genes between cells. Bacterial Cell Structure Bacteria have varying cell shapes. The most common bacteria cell shapes are spherical, rod-shaped, and spiral. Bacterial cells typically contain the following structures: a cell wall, cell membrane, cytoplasm, ribosomes, plasmids, flagella, and a nucleoid region. Cell Wall: An outer covering of the cell that protects the bacterial cell and gives it shape.Cytoplasm: A gel-like substance composed mainly of water that also contains enzymes, salts, cell components, and various organic molecules.Cell Membrane or Plasma Membrane: Surrounds the cells cytoplasm and regulates the flow of substances in and out of the cell.Flagella: Long, whip-like protrusion that aids in cellular locomotion.Ribosomes: Cell structures responsible for protein production.Plasmids: Gene carrying, circular DNA structures that are not involved in reproduction.Nucleoid Region: Area of the cytoplasm that contains the single bacterial DNA molecule. Binary Fission This is a colored transmission electron micrograph (TEM) of an E. coli bacterium in the early stages of binary fission. Credit: CNRI / Getty Images Most bacteria, including Salmonella and E.coli, reproduce by binary fission. During this type of asexual reproduction, the single DNA molecule replicates and both copies attach, at different points,  to the cell membrane.  As the cell begins to grow and elongate, the distance between the two DNA molecules increases. Once the bacterium just about doubles its original size, the cell membrane begins to pinch inward at  the center. Finally, a  cell wall  forms  which separates the two  DNA molecules and divides the original cell into two identical daughter cells. This image shows bacteria growing exponentially in a Petri dish. A single colony can have trillions of bacteria. Wladimir Bulgar / Science Photo Library / Getty Images There are a number of benefits associated with reproduction  through binary fission. A single bacterium is able to reproduce in high numbers at a rapid rate. Under optimum conditions, some bacteria can double their population numbers in a matter of minutes or hours. Another benefit is that no time is wasted searching for a mate since reproduction is asexual. In addition, the daughter cells resulting from binary fission are identical to the original cell. This means that they are well suited for life in their environment. Bacterial Recombination Binary fission is an effective way for bacteria to reproduce, however, it is not without problems. Since the cells produced through this type of reproduction are identical, they are all susceptible to the same types of  threats, such as environmental changes and  antibiotics. These hazards could destroy  an entire colony. In order to avoid such perils, bacteria can become more genetically  varied  through recombination. Recombination involves the transfer of genes between cells.  Bacterial recombination is accomplished through conjugation, transformation, or transduction. Conjugation Some bacteria are capable of transferring pieces of their genes to other bacteria that they contact. During conjugation, one bacterium connects itself to another through a protein tube structure called a pilus. Genes are transferred from one bacterium to the other through this tube. Transformation Some bacteria are capable of taking up DNA from their environment. These DNA remnants most commonly come from dead bacterial cells. During transformation, the bacterium binds the DNA and transports it across the bacterial cell membrane. The new DNA is then incorporated into the bacterial cells DNA. Transduction Transduction is a type of recombination that involves the exchange  of bacterial DNA through bacteriophages. Bacteriophages are viruses that infect bacteria. There are two types of transduction: generalized and specialized transduction. Once a bacteriophage attaches to a bacterium, it inserts its genome into the bacterium. The viral genome, enzymes, and viral components are then replicated and assembled within the host bacterium. Once formed, the new bacteriophages lyse or split open the bacterium, releasing the replicated viruses.  During the assembling process, however, some of the hosts bacterial DNA may become encased in the viral capsid instead of the viral genome. When this bacteriophage infects another bacterium, it injects the DNA fragment from the previously infected bacterium. This DNA fragment then becomes inserted into the DNA of the new bacterium. This type of transduction is called generalized transduction. In specialized transduction, fragments of the host bacteriums DNA become incorporated into the viral genomes of the new bacteriophages. The DNA fragments can then be transferred to any new bacteria that these bacteriophages infect. Sources Reece, Jane B., and Neil A. Campbell. Campbell Biology. Benjamin Cummings, 2011.

How We See Ourselves And Our Abilities - 2244 Words

The purpose of this story was to illustrate the importance of how we see ourselves and our abilities. Many people view intelligence and other skills as gifts that they either have or they do not. If Sally were to do poorly on her final exams, it would be a devastating indication in her eyes, that she does not have the ability to do well. Despite what her mother said, she would think that she is not the â€Å"smartest, most gifted, brilliant kid there is.† She then would place less value in studying because there would be no point if she was going to perform poorly anyways. She would rather invest her time in something she is better at enjoys. For some people, however, failure is not an indication that they do not have the ability to do well, but rather an indication that they must make some changes and never give up in order to gain that ability. The way people view their abilities and interpret the reasons for their behavior can be crucial in determining their success (Aronso n et al., 2013). Obsessed with understanding how people cope with failures, Psychologist Carol Dweck conducted an experiment with elementary school students during which she brought children, one at a time to a room in their school, made them feel relaxed, and then proceeded to give them a series of puzzles to solve that increased each time in the level of difficulty. Dweck initially believed that people either choose to cope with failure or they refused to cope.

Nurses Knowledge Of Pharmacology Samples †MyAssignmenthelp.com

Question: Discuss about the Nurses Knowledge Of Pharmacology. Answer: Introduction The assignment deals with the article titled, Nurses knowledge of pharmacology behind drugs they commonly administer by Ndosi Newell (2009). In the context of the article the assignment discuses the importance of the study, the aims, objectives, research design, data collection, and results obtained from the study. Importance of the study I think that the research is very important not only for Singapore but globally. It is because of the necessity of supplementary pharmacology education for nurses to gain knowledge on drugs they commonly administer. Nurses require this knowledge due to changing nature of the therapeutic regimes, and because they are the front line carers. Lack of pharmacology knowledge may lead to medication error and adverse consequences (Smeulers et al., 2014). Therefore, the authors make the strong case for the study. Title and aims The title of the article is clear and concise. In 9 words the title gives the readers the idea about the research being conducted. However, it does not give a hint of the study nature that is qualitative or quantitative. The aim of the study is clearly stated, which is to determine if the nurses who administer medicines posses adequate knowledge of pharmacology. Further, the study aims to identify if the knowledge is related to their education background or experience. In think the aims and objectives of the study are achieved. Study design The study employed non-experimental causal comparative and correlational design for this research. The research design is appropriate as this is used for identifying the associations among the variables. It is useful to determine the existing differences and the consequences of it among the group of participants (Garber Hollon, 2015). The first and second hypothesis can be well addressed with this design. Data is collected through questionnaire and structured interview method. The instrument selected is justified as it can collect both subjective and objective data from nurses. It will help in measuring the relation between the variables that is education, knowledge and experience level. A small sample size of 42 may hamper the study results (Avery et al., 2014). Results The results of the study are clear and convincing as the data is well presented with charts and bar graphs. The results were statistically significant when measuring the knowledge differences between the junior and senior nurses. Poor pharmacology knowledge was evident among the nurses. The results indicated the correlation between the experience and the knowledge. Discussion The study had provided detailed discussion for the results obtained. The justification for the sample population chosen and the general reason for the low rate of response were also provided. It is convincing to read how the methodology helped in obtaining desired data. The author conducted a thorough literature review that well supported that the data obtained on pharmacology knowledge, Nurses experience and pharmacology knowledge, Nurse Grades and educational background. The study fails to address the learning trends among the nurses and other areas such as pharmacokinetics, drug dosage calculations. Further research The suggestions for further research on this topic are clear and helpful as there is a need of bigger and better sampling and various methods to further explore this area in Singapore. The recommendation on use of cluster sampling will omit the limitations of previous study. Further studies on this topic in Singapore can include the nurses drug dosage calculation and pharmacokinetics. References Avery, C. L., Der, J. S., Whitsel, E. A., Strmer, T. (2014).
