Woodlice Lab Report Example | Topics and Well Written Essays - 750 words

Woodlice - Lab Report Example They have a shell like exoskeleton which progressively shed as they grow. The shedding occurs in two stages were the back half sheds first followed by the front part later usually after two to three days later as opposed to the way moulting process occurs to other antropoda where the cuticle are shed in a single process. Metabolic rate is temperature dependent in woodlice which is in contrast to mammals and bird where their rate of respiration depends directly to the external environmental temperatures (Jordan 100). Woodlice are claimed to have unpleasant taste like that of a urine despite been a crustacean which is different from the taste of other crustacean like lobsters or crabs. Woodlice breathe through their plepodal lungs and live in terrestrial environment usually damp or dark places to reduce the rapid rate at which they lose water through their cuticle and excretion (Sutton, Stephen, Paul, and David 67). Although woodlice are preyed by a wide range of insectivores itâ€℠¢s the spiders that prey on them exclusively. This experiment was conducted to determine the relationship between the variation of traits and the natural selection and the hypothesis of this experiment was that the predator preying on the woodlice determine the speed of woodlice to be found in an environment (Smith, SiaÌ‚n 98). The length and dorsal plate in all woodlice was measured using a microscope and recorded. The speed of three woodlice was obtained by taking two rulers to measure the distance and then assorted utensils for simulating predation and to mimic a predator was simulated and the timer was set from the time all the three woodlice started moving until they all reach the end of the two rulers and then recorded in seconds. Woodlice where placed in large specimen dishes and the predator for this experiment which was a spider was simulated RESULTS The woodlice traits were varying as like were the highest standard deviation error was obtained from the speed and the lowest standard deviation error was obtained from the length while the standard deviation error was zero as illustrated in table(1) below Trait Dorsal plate number Speed (seconds/10 cm) Length (cm) Color (values using soil color chart) Mean 7 21.20833333 0.991666667 5.083333333 Standard Deviation 0 +10.29131828 +0.21450989 +1.248187091 Standard Deviation Error 0 +2.100706547 +0.043786648 +0.254785123 Table (1) showing traits, mean, standard deviation and standard deviation error of woodlice In the frequency distribution below blue represents the total number of woodlice while the red represent the number of woodlice that survived after the predator was unleashed. From the graph the number of survived population is higher than the total populati on between the speeds of 1-20 and the same is exhibited between the speeds of 21-40 and between the speeds of 61-80 but between the speeds of 41-60 no woodlice survived. Frequency distribution of woodlice characterized by speed DISCUSSION From the table and the frequency distribution above it is clearly that there is a relationship between the population of woodlice that survived the experiment and their speed. Woodlice that were much fast and those that are somehow slower survived more compared to those that were of average speed as none of them survived and also the predator

An effective planning process is essential to optimizing the Essay

An effective planning process is essential to optimizing the organizations HR - Essay Example et al. 1999). Therefore, management's first and most fundamental problem is selecting the right individuals with the prospective for development. evenly important is the placement of those individuals in positions in the organizational structure where their talents are most desired. Manpower development instigates with human resources planning also known as manpower planning, which establishes a firm's specific personnel rations. These are attained by a qualitative fortitude of the individual job specifications and of the specific characteristics requisite of a person for the successful performance of each job. Once these job requirements are recognized, it is essential to forecast the number of persons desired for each job. This stage of employment is quantitative, as it entails estimates that are relatively easy to calculate from sales forecasts, labor turnover records, and other sources of data. Human resource planning involves: manpower planning and forecasting; studying the labor market; manpower recruiting; determining supply sources; selecting personnel with appropriate skills and qualifications; placing them on the job; and developing them into more productive employees (McDuff, N. 1995). Human resources planning imply a broad spectrum of activities touching many parts of an organisation. The focus of human resources planning is on decision support and policy making. It is concerned with aggregate flows of people into, within, and out of the organisation and with co-ordination of persons and jobs on an individual level. (Niehaus, 1979). Human resource planning is of great importance as it determines manpower requirements and the means for meeting those requirements in order to carry out the integrated plans of the organization (Fombrun, C.J, Tichy, N M, Devanna, M.A, 1984). It includes determining the required types of skills and capabilities and the needed numbers of people, as well as the location and timing of the manpower needs. Optimization in manpower planning is emergent where human resources are treated as capital assets in much the same way that plant and equipment are currently treated. In essence, this system attempts through an accounting model to measure the cost of the resources, what it would cost to reinstate the resources, and what their value would be based upon their potential earning ability. This system emphasizes that man is a unique entity needing individualized consideration. Thus, managers are becoming more concerned with accounting for the human resources, both in terms

Visual Journalist Websites Research Paper Example | Topics and Well Written Essays - 250 words

Visual Journalist Websites - Research Paper Example All the photographers seem interested in imagery that combines giving their photos life as well as motion. I spent an average of 5 minutes on websites created by Tatu Blomqvist, Jody MacDonald, and Jack Gruber since still imagery did not attract my attention that much (thomasboyd 2). In contrast, I spent an average of 10 minutes on Ami Vitale’s Website and 20 minutes on Thomas’s website since the overall pictorial display attracted my attention due to the amount of creativity implemented in designing slideshows displayed in the WebPages. After pasting the names of the photographers individually on Google, I noticed a specific trend that every artist has links to several social networking sites such as Twitter, Facebook, and LinkedIn. The artists have a high dependency on the social sites in order to popularize their work as well as their hosting websites (jody macdonald photography 1). A closer look revealed that all the artists had posted their profiles and portfolios on these sites in a bid to increase their visibility to potential clients. It a good way of interacting with fellow enthusiasts of photography as well as marketing their skills and previous work that is ready for sale. If I was to design my own website based on the format implemented by the above photography artists, I would include more links to my profile in order to market my skills in the trade to potential clients (Vitale 2). In addition, I would also include an online subscriber’s log that can allow funs of my work to view and download photos for their own personal consumption (Gruber 1). This will help me to monitor the traffic directed to my websites as a way of gauging its popularity among photography lovers. Lastly, I would include a safe billing system on the website that can allow online shoppers to pay for their purchases using their credit

Erotic elements in The Brothers Menaechmus Essay

Erotic elements in The Brothers Menaechmus - Essay Example There is a homoerotic and incestuous undertone to the union of the brothers at the end of the play that contributes to the production of humor. This paper shall seek to analyse these aspects of the play and why these can or cannot be used in a modern play. Erotic elements in The Brothers Menaechmus The erotic elements in The Brothers Menaechmus contribute greatly to the comedy that is an intrinsic part of the play. The presence of a wife and a mistress and the confusion that ensues is something that is a stock situation that is used for humor in many plays. Plautus combines this with the presence of the twin brothers who look exactly like each other to create situations that are not only funny but also educative and subversive of contemporary ideas of appearances and reality. Subversion occurs at another level, where the homoerotic element is hinted at. However, it is not developed fully and is turned into another occasion for laughter and the production of comedy. The name Erotium i n itself lends itself to suggestive explanations that produce situations that are worthy of laughter to an audience that heard the dialogues in the original Latin that the play was written in. The recourse that Menaechmus takes is that of taking refuge in the arms of his mistress. His wife remains an insignificant character as opposed to the prostitute. His wife is not even provided with a name in most translations.

Liberty Essay Example | Topics and Well Written Essays - 500 words

Liberty - Essay Example Other academicians have related life to existence in state of nature under a social contract. Liberty is connoted into two major different kinds. Classical liberalists and individualists have conceptualized liberty as consisting of individual freedom outside coercision and compulsion, this is the kind of liberty known as Negative liberty.Whereas, social liberalists conceptualize liberty with emphasis to the social structure and agency, this is the second kind of liberty known as Positive liberty .In summary we basically have two kinds of liberty which are: positive liberty and negative liberty. Positive liberty explains that a person can find freedom in his ability to exercise agency, by having adequate power and resources to enable him to do his will without being misled by societal views such as sexism, structuralism and racism. Thomas Hobbes explains that``a free man is he that†¦.is not hindered to do what he hath the will to do `` Hobbes (235).John Stuart Mill was the first to recognize that there is a difference between liberty as a freedom of action or to act and liberty as an absence of coercion. According to Berlin (221), the difference between the two perspectives as opposite concepts of liberty; positive liberty and negative liberty where the latter manifested a negative condition of individual protection from tyranny as well as arbitrary exercise to authority. Whereas the former meant the ability to have means or opportunity other than to lack restraint of doing things or acting. The term negative liberty has different noteworthy aspects.Firstly; it defines zones or realms of freedom in the aspect of science (science of law) Hobbes (197).The distinguishing idea between the two kinds of liberty is traced back to Kant who examined it in the year 1940s; he explained that the two kinds of liberty are not merely different but rivals. Positive liberty requires not

Plato - democracy Essay Example for Free

Plato democracy Essay Aristotle was a pupil of the famous philosopher Plato. During his lifetime (384-322 BC) he learned and taught Socratic philosophy which was taught to him. He was taught this philosophy by Plato, who is responsible for all of Socrates written works since Socrates himself did not write down his teachings. During his teen years he was enrolled in Platos â€Å"Academy† where he then taught for about 20 years after his graduation. After this he started his own school called the â€Å"Lyceum†. Here he  taught of philosophy and politics. His political teaching broke down regimes into six categories. These categories are then broken down into three groups of pairs. Each of these pairs has one â€Å"good† form and one â€Å"bad† form. The first tier consists of Monarchy and Tyranny. Each of these is â€Å"the rule of the one†, but according to Aristotle, a Monarchy was better than Tyranny because a Monarch puts the needs of his people before his own. The second tier is Oligarchy and Aristocracy. Both of these are  Ã¢â‚¬Å"the rule of the few† but Oligarchy was considered a better form because the Oligarchy was not necessarily influenced by money and class whereas Aristocracy was. The third tier was Polity and Democracy. Both of these were â€Å"the rule of the many† but Democracy was considered better for the same reasons that Oligarchy was better than Aristocracy. With his teachings of philosophy, and his image of an ideal regime which could possibly be attainable (unlike his predecessor Plato â€Å"ideal city†). he was a very influential character in the future of society. Due to his father being a court physician for King Amyntas of Macedonia, Aristotle was a childhood friend of the later King Phillip. His friendship with King Phillip was the main reason he was asked to teach Phillips son Alexander (later known as Alexander the Great). Aristotle played a pivotal role in the development of Alexander the Great and it is quite possible that he would have not had such a conquest as he did had it not been for Aristotles.
