Biology - Essay Example All living things are composed of one (unicellular) or more (multicellular) cells. All the cells gather energy and utilize energy for growth, reproduction, repairing processes etc. Many different types of cells perform different jobs and together co-ordinate and keep living beings alive. Unicellular (one celled) organisms are bacteria and paramecium, while fungi, plants and animals are multicellular (many cells). The living things are classified into prokaryotes and eukaryotes. Bacterial cells are prokaryotes with simple structure without complex organelle system. Figure 1.A (1) shows prokaryotic cell structure of unicellular bacteria and Figure 1. B shows many bacterial cells. Bacteria are the smallest organism on our planet. Plant cells (Figure 2) (2) form plants. Animal cells (Figure 3) (3) form animals. The plants and animal cells are eukaryotes having larger size than eukaryotes and have complex organelle system. Cells put together form tissues. Tissues form organs. The organs put together form organ system. The organ systems put together make plants and animals. The organelle nucleus in the eukaryotic cell accommodates deoxyribose nucleic acid (DNA) which is a blueprint of our life. The DNA houses the intelligence needed to determine the characteristic shape (structure) and job (function) of all living creatures. We get this DNA from our parents which decides our physical make up, our intelligence, and it reflects our personality. DNA of a cell decides the characteristic role of that cell it has to play in our body. This double helix DNA is like a spiral staircase. DNA can be extracted from any living things and can be seen in a test tube with naked eye in the form of long ropy strings. This DNA is made up of four nucleotides A, T, C and G (Figure 4) (4). The various permutations and combinations of these nucleotides differentiate each living being. It decides who and how we should be. The human beings

When the Antibiotics Quit Working Assignment Example | Topics and Well Written Essays - 500 words

When the Antibiotics Quit Working - Assignment Example An antibiotic is a medication that is used to cure pathologic conditions of the body that result mainly due to bacterial infections. This group of drugs has the capability of restricting the growth of bacteria by many mechanisms and they are particularly very useful because these drugs possess the specificity of mainly attacking the bacteria. This property makes them very useful because this allows them to specifically target the microorganisms and not the host cells. Antibiotics are drugs which are prescribed by the doctors for the treatment of severe infections which are caused by bacteria. These drugs are not useful against viral infections because they are not effective in that case. The use of antibiotics has greatly increased over the years. With this rise in the prescription of these medications, there has also been a rise in their ineffectiveness. This incompetence of the drugs results due to the development of antibiotic resistant bacteria. The reason behind this is that when the bacteria come under attack by these drugs, they have the capability to undergo certain changes via many mechanisms which make them resistant to that particular drug. After the development of one strain of resistant bacteria, there is a quick spread and if the same bacterium infects another person, it will still be resistant to the antibiotics. This can be very harmful and it is via this mechanism that the antibiotic resistant tuberculosis has resulted. Hospitals serve as pools for the generation of these resistant strains. Also the immediate prescription of antibiotics without an initial treatment with alternative medications can be counted as a reason for leading towards this prob lem. Antibiotic overuse with animals also results in resistant bacterial strains within animals and when these are consumed by humans, they also result in diseases by bacteria which do not respond to certain

Influence and Change in Organizations Essay Example | Topics and Well Written Essays - 1000 words

Influence and Change in Organizations - Essay Example The ‘best practices’ primarily suggest clarity of purpose. This implies that the underlying problem needs to be identified – why is change needed and how these surveys could influence change. To implement best practices, the organization must be able to communicate and have a clear understanding with the employees on why the organization is undertaking the 360 degree feedback survey (Wimer & Nowack, 2006). There should be no assumptions that it would inevitably lead to enhanced leadership skills (McCarthy & Garavan, 2007). This necessitates that the entire process must be explicitly explained which could help overcome management resistance. This would also ensure rater receptivity because unless the managers accept the feedback they would not engage in development planning. Beliefs about change influence acceptance and hence perceptions of fairness is essential. Multisource feedback is supposed to limit biases and hence anonymity of some raters may have to be main tained. Anonymous raters tend to be candid and positive and usually provide a higher rating (CCL, 2011). However, who rates who is important and if managers are not receptive to certain raters, the effect of MSF is nullified. Thus while some raters should be anonymous, managers should also be allowed to choose some raters. If they are allowed to choose all the raters biases could creep in. Raters should be selected on the basis of the objective criteria and should be jointly selected by the rater and the rate. This would enhance acceptance and perceptions of fairness. To ensure employee readinesss, organizational culture should be supportive to conduct the 365-degree feedback survey (Morgeson, Mumford & Campion, 2005). If the managers have the confidence in the system and perceive fairness, they would be highly likely to make changes. Specific training interventions could help educate the managers about the process, the intentions and the expected outcome (McCarthy & Garavan, 2007). Rater training may help eliminate errors and also help eliminate cynicism from within the organization as cynicism can reduce the impact of the MSF. Rater training should include, in addition to training in reliable and accurate ratings, discussions on how the survey instrument was created and how the information will be used. Besides, anonymity should be assured through confidentiality (Morgeson, Mumford & Campion, 2005). Confidentiality of the rating process is also important and critical to the success of the process. The recipients or the raters too need to be trained in acceptance of the ratings and on how to handle negative feedback. Morgeson, Mumford and Campion (2005) found that most organizations used the surveys for developmental purposes and that it should categorically not be used to determine salaries. When used for developmental purpose the data is the property of the people being rated while when used for administrative purposes, the organization owns the data. To ac hieve the best results, people should be given control of their own data (Wimer & Nowack, 2006). People will feel empowered if they can choose with whom and to what extent they share their feedback. However, the feedback recipient should have access to a trained feedback giver who has experience with assessment. The recipients should also be provided guidance on how to share data and use it constructively. However, an overwhelming amount of data may

Internet and the E-Commerce Flower Business Research Paper

The final process normally involves the product delivery to the customer. This paper seeks to explain the developments achieved in the business industry by applying the internet as the trading media and the flower business as a reference. Impacts of the Internet on Global Finances Grosse explains that the internet has changed the global financial trends sine 1990 from offering financial service like banking to the provision of insurance packages that have found new measures in selling their provisions (Grosse, 35). He majorly dwells on the positive implications that the internet has accorded the banking industry with the electrical money transfer system that ensures safer measures in handling the transactions. It had become cumbersome top queue for longer hours to be serviced by the bank tellers and sometimes insecurities attributed to mugging and loss of money. The major contribution that the E-commerce has directed in the market is the management of the business time, offering minimal period spent on negotiations. The constituent of the trading commodity may be tangible or limited to internet transfer trends including money transfer. The E-business entity means the transaction happens exclusively via the electronic device, and in this case the internet provides the platform (Basu, 18). The E-commerce entity had initially been crude and mostly provided unsafe venues of trade because hackers could gain access to the information that jeopardizes the overall process. With several measures and security inscriptions, safer measures have been applied to reduce on piracy as a series of input codes and security firewalls developed to promote the medium.

Through exchange of policies, figures in numbers ad possibly images of the advertised entity, the agreement can be solved easily. The negotiation oversees the transfer of the agreement over the internet

Regression Analysis on Marathon Finishing Times Research Paper

Regression Analysis on Marathon Finishing Times - Research Paper Example These five variables were taken to be independent variables but the marathon finishing time was taken to be dependent. The main procedure utilized in this study was regression analysis. It was utilized to explain the total variation of the dependent variable, the marathon finishing time. The dependent variable was accompanied by 5 variables, which were tested against the dependent variable to determine how much of the total variation is explained. The analyses also discussed the comparison of the different regression models, and determine which model is the most effective. In regards to the regression analysis results, it is clearly evident that model 4 and 5 are the strongest model and model 1 being the weakest. Model 2 and 3 does not apply because of the reasons given .Therefore, the number of half marathon run, age and number of days of training a week have an influence on the half marathon finishing time that is related to the athlete performance. The numbers of half marathon run and number of days of training a week have a negative moderate influence on the half marathon finishing time, while the age has a weak positive influence on the half marathon finishing time. ... ed criteria, which normally entails perceived potential in relation to perceived athletic career cost and the level of achievements ( Lundqvist and Hassmen2009). Successful athletic careers are related to achieving individual peak in performance that corresponds to individual environment and resources (Lavallee and Wylleman, 2000).There are factors which are believed to affect the performance of the athlete and this study was to ascertain this basing on few chosen factors among several others ( Lundqvist and Hassmen,2009). The first factor chosen is age which is known to affect the performance of the athlete, the second one is number of sleeping hours, then number of time eating out a week, the number of days of training a week and the number of marathons ran. All this factors have been supported by research to have an influence to the athlete performance (Lavallee and Wylleman, 2000) and it was my task to prove this on the 37 athletes who are specialized in running half marathon. Re gression Analysis The survey conducted was from runners at a local 5k here on Guam. A questionnaire was used to collect the data and the sample was randomly selected. This was important because it represented the population of athlete. The challenge faced during data collection was that some individuals were never willing to respond. The first regression analysis step was to input all the collected data from the surveys into a spreadsheet. This process allows efficient running of regression models. After all the data was entered, there was formulation of the initial regression model. The first model consists of my Y variable that was the half marathon finishing time and one independent variable that was age. Different models were run to ascertain which model was the strongest as well as to

Joseph Nyes Rise of Chana and American Power Coursework

Joseph Nyes Rise of Chana and American Power - Coursework Example In brief, the good relationship dipped since the people of China perceived the recession as a decline of USA and their subsequent rise therefore they ascended to super power position. Absolute decline refers to a situation where there is decay or complete exhaustion while relative decline in its part is where the resources present in another country are used more efficiently and effectively. He mentioned that Asia and China in the past housed close to 70% of world population thereby contributing to the market. In recent years, most of the world population still live in Asia and China yet approximately 20% of world products come from Asia. Thus, it is a return because Asia and China seeks to meet its past contribution to the market by balancing it population and ability. He mentions that too little power like calories is wrong since t can make one to expire or perish. On the other hand, too much power does not represent goodness just like calories in human

Developing a Medical and Fitness Standard Essay

Developing a Medical and Fitness Standard - Essay Example As the paper stresses the medical and fitness standards within every department is essential. Its necessity is to monitor and promote safety when working. The job for the firefighters is a physical one and there is need to keep the employs fit. Ways of keeping the employees fit is through physical exercises. Just imagine how it would be if an athlete went to a running competition without trainings and exercises? It would be a mess because the athlete will not be physically fit and will tire quickly and may not finish the race. If the athlete wants to win a race, then rigorous exercises must be incorporated. According to the report findings when responding to a fire, sometimes the fire fighters may be involved in a physical injury. Therefore, after every firefighting response, they should be cross-examined by a medical practitioner to ensure that they are well. Where they have been hurt, medication should begin immediately. The regular check will even motivate the employees to perform well when working because they have peace of mind and their health is being taken care of by the management. When developing the medical and fitness standards, there should be injury programs to check on the overall health of the employees and their wellbeing. Eating habits and diet should be monitored. Health can be determined by the types of foods the officers take. Also, it predicts the physical fitness of an individual. The officers should be flexible and it should be youthful.
