Diffusion and Osmosis Lab free essay sample

To simulate and observe the diffusion of solutes and the osmosis of water through a semipermeable membrane through color change and sugar tests. 2. To speculate osmosis occurring In dialysis bags and potato cores by comparing percentage change in masses. Background information: Molecules are always in random, constant movement due to their kinetic energy. This causes the molecules of a cell to move around and bump into each other. The random movement of molecules from an area of high concentration to low is called iffusion. Osmosis, a specific kind of diffusion with respect to water takes place in the cells. This kind of diffusion is where water moves through a selectively permeable membrane, that Is, a membrane that only allows specific molecules to pass through. Diffusion and osmosis stops when a dynamic equilibrium Is reached, that Is, the concentration on both sides are equal to each other. To be noted, that at this point, molecules are still In constant motion and random movement; however, the rates at which molecules moving from one area to another are equal and there is no net ovement occurring between the two areas. We will write a custom essay sample on Diffusion and Osmosis Lab or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page If two solutions have reached this equilibrium state, they are said to be isotonic. If they differ, the solution with a higher concentration of solutes is hypertonic with respect to the other; the solution with lower concentration is hypotonic. Water potential describes the tendency of water moving to another area. Since solutions always tend to reach a state of equilibrium, water usually moves from a hypotonic solution to a hypertonic solution in order to dilute the higher concentration. Therefore, we say that hypotonic solutions have a ower solute concentration and a higher water potential. The net movement of water In a plant cell can be described using the two terms, turgor pressure and plasmolysis. Turgor pressure refers to the pressure of water exerting against Its plasma membrane, which helps maintain the shape of the cell. When a plant cell is placed in a hypotonic environment, water moves into the cell, causing higher turgor pressure. However, when placed in a hypertonic solution, water moves out of the plant cell, therefore causing the cell to lose its turgor pressure. The loss of water and urgor pressure while a cell is in a hypertonic solution is called plasmolysis. In conducting this lab, we will be simulating diffusion and osmosis that occurs in the cells by using dialysis bags potato cores. In comparing the percentage changes in mass of these test objects after an isotonic state has been reached, we will be able to speculate If water has moved into or out of the bag. Materials: Part A: dlalysls tubing, Iodine Potassium Iodide (IKI) solution, 15% glucose/ 1% starch solution, glucose Testape or Lugols solution, distilled water, and a 250mL beaker. nd a 1. M sucrose solution; six 250-mL beakers or cups, and a scale. Part C: a potato, knife, potato core borers, distilled water; 0. 2M, 0. 4M, 0. 6M, 0. 8M, and a 1. 0M sucrose solution, and a scale. Procedure: Safety Precautions: Keep the potato core pointing away from you and other students when cutting the potato cores out Be careful cutting the potato slices, ask an adult or get a responsible person. Reference: Refer to Lab One Diffusion and Osmosis Handout Observations: Data: Analysis: Part A: Lab IA Questions: 1. Glucose is leaving the bag, we know this because initially there was no change in colour of the Testape in the beaker, but our final data shows, there was glucose present in the beaker. The Iodine-potassium-lodide is entering the bag because initially we tested the beaker for starch using the Iodine-potassium-lodide solution and at that time, the solution color in the bag was clear, by the end of the experiment, it was a dark blue color, which is a positive test for starch. Water is also entering the bag, because although the initial and final mass of the bag before and fter the soaking was not recorded, we noticed an increase in size of the dialysis bag. 2. The results show the IKI moved from the beaker to the bag, causing the change of color of the solution in the bag. This was because there was a higher concentration of IKI molecules in the beaker than in the bag, so the IKI molecules moved from an area of high concentration to an area of lower concentration in a process called diffusion

Social Close Gap Social Justice Campaign †Myassignmenthelp.Com

Question: Discuss About The Social Close Gap Social Justice Campaign? Answer: Introducation: The closing the gap policy was introduced by the Australian government with an aim to reducing the discrimination faced by the Australian aboriginal and Torres island people. The motive behind the implementation of the policy was to provide equal opportunities to the Aboriginal and Torres islander people. Thus, the policies aimed at reducing the disadvantages with respect to poor life expectancy, increased rate of mortality in children, reduced exposure to compulsory education levels. The policy was passed in response to the drafting of the Social justice report, 2005 and close the gap social justice campaign. The Aboriginal Australians were also known as the indigenous Australians. They were the first inhabitants of the main land Australia and had a unique culture and language of their own. These people held strong spiritual connections towards their land and made their living through agriculture and farming. However, the colonisation of the Australian mainland by the Britishers had diverse effects of the culture and survival of the indigenous Australians. The British under the leadership of Thomas Cook took possession of the land inhabited by the indigenous Australians. Additionally, they also removed the white children from their aboriginal ancestries. This resulted in a situation of political unrest and discrimination towards the aboriginal Australians management. In March 2008, the aboriginal and Torres island people agreed to sign a treaty with the Australian government to gain equal health standards between the aboriginal and Torres island group (Michael et al. 2017). The council of Australian government (COAG) laid down a number of policies to meet the target health requirements of the aboriginal and the Torres islander people. The targets had been broken down into a number of components. The policies aimed at reducing the mortality rate of indigenous children below within a decade. As mentioned by Browne, Hayes Gleeson (2014),the policy was also put into action in order to ensure that free and basic education is provided to the children of indigenous origin. The education was seen as an important consortium through which equal employment opportunities could be provided to the aboriginal and the Torres island group. The gap recorded between indigenous and non-indigenous life expectancy at birth had been noted as 11.5 years for the males and 10 years for the females. As per the data recorded, the expected life expectancy at birth of the indigenous Australians was recorded at 69.1 years for males and 73.7 years for females. This was 10.6 and 9.5 years lower than that of the non-indigenous Australians respectively. Moreover, above 65 % of indigenous deaths were found to occur before the age of 55, compared to only 19% in the non-indigenous Australians (World Health Organization 2013). The government plans to close the gap with regards to the availability of the basic amenities such as a positive and healthy environment for optimum growth and prosperity of indigenous children. In this regard, the Population Health Research Network (PHRN) was setup by the Australian government to collect important and vital health related information from across the nation. This helped in the drafting of important policies for bringing about improvement within the health context of Australian aboriginal and Torres islander children. Thus, the SANT data link was established in 2009 to conduct important population based research and provide relevant data links to the government for further policy marketing and analysis (World Health Organization 2013). The close the gap policy has significant contribution in the life of the events of the aboriginal and the Torres island people. The main aim of the campaign was to close the gap between the aboriginal and the Torres island people with regards to life expectancy and better social inclusion policies. The close the gap program was formulated with main emphasis upon the human rights and privileges possessed by the indigenous Australians. The successful implementation of the program helped in ensuring that the infant mortality rates are controlled along with improving the life expectancy of the indigenous Australians. As mentioned by Parker Milroy (2014), the indigenous Australians such as the aboriginal and the Torres island group had to face severe discrimination due to their unique language and different cultural aspects. The aboriginal and the Torres island people had been forcibly removed from their land due to British colonisation. However as argued by Sibthorpe et al. (2017), the people shared a strong cultural and spiritual connect with their land. Thus, the British colonisation had a disruptive effect on the communal identity of the aboriginal and Torres island group. There had been a constant fight ever since for the basic rights and privileges between the Australian indigenous and the non-indigenous groups. As mentioned by Lannigan (2016), there had been no considerable reforms in the government policy making with respect to the indigenous Australians. However, as commented by Parker Milroy (2014), the implementation of close the gap policy would help in bringing about important constitutional reforms. The changes implemented would help in meeting the educational and health requirements of the deprived group. Thus, the policies may help in incorporating social inclusion of the Australian aboriginal and the Torres island group. Ear diseases have been highly prevalent in the Australian aboriginal and the Torres Strait islander children. As commented by Kilcullen, Swinbourne, Cadet?James (2016), high rates of hearing impairment have been noted in the Australian aboriginal and Torres islander children. This may be attributed to a number of factors such as overcrowding of household, passive smoking, premature birth, bottle feeding and malnutrition. The profound ear diseases found in the indigenous children have been widely due to otitis media. The disease has been found to occur within weeks of the birth of the child and may continue into adulthood. As commented by Stoneham, Goodman, Daube (2014), the hearing impairmentbusiness may lead to delay in speech and educational attainment of the child. The close the gap policy had been put into effect to provide additional infrastructure for the prevention and treatment of such diseases within the children. Thus, programs such as Haemophilus influenzea type b (hib) vaccination, neonatal screening along with and antibiotic treatments help in the management of such conditions. The close the gap programme helps in incorporating some of the prerequisites for the prevention and control of the otitis media in the indigenous children. Some of the effective measures such as routine health check up help in early analysis and provision of suitable remedial solution. The policy advocates the implementation of The Child Hearing Health Coordinator Program. The program ascertain that a case management model of service delivery is followed where the coordinator in-charge provides for a communicating and effective service retrieval channel between the children and the specialists. The close the gap program had contributed significantly in improving some of the basic amenities such as food, nutrition available to the indigenous group. As commented by Lannigan (2016), the implementation of the policy in 2009 had helped in removing the perils of racial discrimination faced by the indigenous group of people. The Close the Gap program further supported the conduct of the systematic review in 2006. The reviews were aimed at addressing the issue of racial discrimination and promote respect for cultural diversity along with removing the barriers to the access of adequate health services. A number of challenges are faced in the implementation of the Close the Gap program. The challenges are faced across multidisciplinary channels. One of the prime challenges faced by the government is to regularly and accurately monitor key health indicators. As commented by Dobia Roffey (2017), incorrect recording of the census might also affect the quality and timely availability of health care services to the indigenous group of people. The five year gap between the census data collection often affects the depiction of the true picture of the changes. However as argued by Panaretto et al. (2014), additional hindrances may be faced in implementation of close the gap program. The program aims at bringing more and more people within the benefits of education cover and improved health services. The language and cultural paradoxes of the indigenous Australians are different from the modern day white Australians which further intensifies into racism and discriminatory behaviours. Reports and evidences have suggested that only 1% of workforces working in health care are of indigenous origin and. Additionally, they are provided with greater amount of resistance from the white Australians practising in healthcare such as the nurses and midwives among others. This often result into discriminatory behaviour at workplace and larger communication gaps between the indigenous health professionals and the white Australians. On a concluding note, the close the gap program has the potential of neutralizing the racial and communal discrimination that the indigenous Australians had been subjected to. In this respect, implementing the policy would have been fruitful in achieving the targets aimed at reducing the social distresses suffered by the indigenous Australians. The implementation of the policy would help in meeting the educational as well as the health needs of the indigenous Australians. The current essay discusses the perils of Otitis media in damaging the hearing of the indigenous Australian children. The concern is grave and could be addressed with the conducting of neonatal screening. However, the implementation of such programmes is based upon sufficient help and support from the government along with community participation. However, lack of knowledge often becomes a limitation in achieving the target. Additionally, regularly monitoring the health care services often becomes a limitation on th e part of the government. This might be attributed to the gaps within the data collection process. The Australian aboriginal and Torres islander group possess a huge amount of cultural and social myths. In their culture health issues are rather seen as a matter of privacy and should be kept confidential. Thus, such false beliefs held by the people often make the delivery of service difficult. However, reports and evidences have suggested that with the implementation of the model a huge number of infant mortality rates had been brought down. Repeated and authentic data collection procedures helps in accessing the improvements brought about in the life expectancy of the indigenous Australians.

Through Much Research I Have Found 3 Advertisements For Popular Compan

Through much research I have found 3 advertisements for popular companies that range from well done to tasteless. Introduced first will be an ad that is done well and with taste. Then, an advertisement that seems to be done poorly and has a message that could be misunderstood by some people. Finally, a totally tasteless ad that has no right to be seen by anyone with manners. This first ad is from the Absolut Vodka company, although the product could be controversial, the actual content is simple and would not create an uproar. Absolut has a great ad compaign that uses familiar objects, sport teams, and places to push their products. It also appears that this advertisement it targeted at a more mature person and not a child or minor. The second article is by Nissan and it showing it's new Sport Utility Vehicle. Although the billboard could be found humorous, it also carries a message that dangerous driving is all right. It seems to say, go ahead, flip it over, some one else will pay for your mistake. This billboard has poor composition and could have been designed better, but is not the worst article found. This last advertisement is for Southern Comfort Liquor. This article definitely violates the ethics of advertising. The message of the billboard is that, if u get a girl hammered with our alcohol, she'll give it up to you. This billboard should not be allowed to be seen. Advertising that indorses what could be considered date rape should be taken off the market. In conclusion, it's not always what the article is advertising that dictates the content. This paper shows 2 different articles for alcoholic products that are on different side of the spectrum. While one is done tastefully, the other shows no regard for a female. Advertising is seen by many impressionable people, we must be careful what is going out there.

The Past of Pay is Paid

The Past of Pay is Paid The Past of Pay is Paid The Past of Pay is Paid By Maeve Maddox A reader expresses dismay at lapses in the spelling of the past form of the verb pay:    An article in the Burlington (VT) Free Press today had  this heading:   Isle La Motte to vote on spending repayed funds. [W]hen did repayed become an acceptable word?   The answer, of course, is that it hasn’t. Note: a Free Press reader pointed out the misspelling on the paper’s site: repayed Who buyed your English classes? and the misspelled word was promptly corrected. Our DWT reader offers another, more unfortunate example: My friends son received a report card from his teacher that read:   Tate payed attention in class.   Language changes and irregular verbs morph into regular verbs with -ed endings, but some words are in such frequent use that the older forms endure. It’s difficult to understand how someone educated as a teacher or a journalist could fail to master such a basic irregular spelling as paid. The OED does include the spelling â€Å"payed† as a form used â€Å"chiefly in the nautical sense†: pay: v. To smear or cover (a wooden surface or join, esp. the seams of a ship) with pitch, tar, or other substance, so as to make watertight or resistant to damage. Also (occas.) with over. Merriam-Webster lists â€Å"payed† as a past form used for another nautical expression: pay: to slacken (as a rope) and allow to run out For the everyday sense of pay as remuneration, the past tense is paid. Two other common verbs ending in -ay that also change the y to i in the past are say and lay: say/said/have said lay/laid/have laid Want to improve your English in five minutes a day?

Responsibility and brand advertising in the alcoholic beverage market Essay - 1

Responsibility and brand advertising in the alcoholic beverage market. The modelling of normative drinking behaviour. by Debra Jones Ringold - Essay Example Thesis Statement: The purpose of this essay is to critically review the above article by Ringold (2008). The theories, ideas or beliefs that the author tested will be summarised; the contents of the article will be condensed; and the weaknesses and strengths of the research study will be critically analysed. Ringold (2008) states that her study revealed moderate consumption of alcoholic beverages as the norm in the United States. This is similar to the results of the Gallup polls (2004) which have indicated the same outcome since 1939. The recommendations given by the United States Dietary Guidelines on moderate drinking was consistent with the consumption found in 90% of people who consume alcohol. This is supported by Saad (2005), who states that underage drinking and alcohol abuse have considerably reduced in the last three decades. The per capita consumption of alcohol has continued to decline over the past twenty-five years, states NIAAA (2006). The main aim of the article by Ringold (2008) is to study the outcome of alcoholic beverage advertising on its consumption levels. The research study takes into consideration the actual and desired impacts of, describes and evaluates the controversy regarding industry-sponsored responsibility campaigns; and identifies a number of issues that require future research. The results of the study reveal that alcoholic beverage advertising does not exert a material influence on total consumption or abuse. On the other hand, it models normative drinking behaviour, hence may be a crucial inhibitor of alchohol misuse. Responsibility efforts sponsored by industry, by government and by nonprofits lead to desired changes, modeling desired drinking behaviours, and may be more beneficial for heavier drinkers. The article by Ringold (2008) is timely, because of the continued trend of increased expenditure on advertising, undertaken by alcohol manufacturers. This is

Litature - Essay Example American Revolution and the declaration of independence play a vital role in the process of identity formation and one can find the subterranean interrelation between American literature and American identity. Technologies and electronic developments affect the reading habit and it also influences the literature in America. American Renaissance is often considered as a hopeful movement that visualized America as the real descendant to the great western civilization. Renaissance which occurred in mid 19th century has paved the way for an overall change in American social as well as literary filed. During the periods of 1800 to 1870, most of the American masterpieces were produced. After a detailed analysis of the history of American literature one can see that after renaissance writers in America followed a new style or method of storytelling and versification. The expression of national spirit is another major characteristic of new American style. Current political and cultural sphere is filled with the evilness of terrorism and other types of crisis. One can feel that literature should illustrate or reflect the evilness and futility of terrorism and other regional polarizations. The exponents of transcendentalism have focused in a new culture based on native rudiments or ‘Americans’. American ideal of individual consciousness and actions is the most significant feature of American style. Ralph Waldo Emerson, one of the striking figures in Renaissance literature has given more emphasis on the philosophy of self reliance which represents the need for the individual to check most of all types of social customs and to change ideas by the commonly accepted standards and values of the community. Self- reliance, individualistic power, enthusiastic feelings about the fascination of power, superior human intelligence and the philosophy of action are visible in American writings during Renaissance period.
