Osmosis :: Papers

Osmosis Introduction Osmosis is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water concentration. The aim of the investigation is to find the variables that affect the rate of osmosis and how they affect the rate of reaction. The variables that affect the rate of reaction of osmosis are, Â · The surface area of the object, Â · The concentration of the solution, Â · Temperature of the experiment Surface area If the surface area of the object is larger then more molecules can pass through the semi-permeable membrane. This will ultimately increase the rate of reaction. [IMAGE] [IMAGE] [IMAGE][IMAGE] Small surface area Large surface area Concentration If the concentration of the solution is high then it will contain more molecules and so the rate of reaction will be shorter. [IMAGE] [IMAGE] Low concentration High concentration Temperature of the experiment Generally the higher the temperature, the less time it takes for a reaction. But with living cells there is a point at which the cell will be denatured therefore the rate of reaction will be altered, as the cells are no longer functioning. Hypothesis ========== Osmosis is defined as the movement of water or any other solution's molecules from a region of highly concentrated solution to a region of less concentrated solution. This movement must take place across a partially permeable membrane such as a cell wall, which lets smaller molecules such as water through but does not allow bigger molecules to pass through. The molecules will continue to diffuse until the area in which the molecules are found reaches a state of equilibrium, meaning that the molecules are randomly distributed throughout an object, with no area having a higher or lower concentration than any other. To make this investigation fair, the conditions will be as follows: Changed variable Constants

Devoted and Helpful Essay

We all have that one person whom we regard highly of. That person we look up to as a role model. But what is a role model? A role model would be someone who is devoted in most aspects of life to achieve success in the future and always willing to be help usually not caring what the task is. We do not necessarily see this person as particularly perfect but just a good goal of whom we hope to become someday. My sister Priscinda is my role model and she has these traits that I find admirable: being devoted and helpful. Why is being devoted and helpful qualities seen in someone whom we should regard highly of? The reason being is that being devoted is someone who is very loyal and loving that one person who has dedicated there time to another. Being devoted means commitment, putting others needs before oneself, trusting one another. Can we imagine a life without devotion? No commitment, no follow-through, no grounding in what really matters. Maybe that’s how most people live – losing their center in the face of compelling people and situations, not taking the time to reflect on what is important to themselves. Along with devotion you must also be helpful, we were all taught to help others when we were young. Helpful is being able to help others without expecting anything in return and just doing it out of the kindness of a person’s heart. It is a value that parents and teachers have been sharing for ages. Yet, sometimes we get so focused in our own world that we do not always go out of our way to help others— we just have too much on our minds and too much on our plates to even bother what others are doing. Being devoted and helpful is of such importance in a person because without these people we would not have anyone to look up to and we would live in a selfish world. Moreover,  one person whom I know that exemplifies these traits best is my older sister Priscinda. She is one person that I know best at being devoted whether its  school, work, family she is the one to stay committed to be able to succeed.

Pandora in Art and Culture essays

Pandora in Art and Culture essays According to our understanding of Greek mythology, Pandora was the first woman created by the gods and given to the humans. According to various versions of the myth she was a true gift to them, or a trap, or even a punishment for accepting forbidden fire. One way or another, she was gifted with great beauty and important skills and charms. Pandora's very name means "All Gifted," and suggests that the gods were most generous to her and to humans through her. However, she was also gifted with a magic jar she was instructed never to open. (Over time this jar was changed into a box in most retellings) When her curiosity ot the better of her and she opened the box, all the ills of the world were released. At the bottom of This archetypical story of how woman infected the world with evil is closely related, and one might even say identical, to the Judeo-Christian story of Eve and the forbidden fruit. Historically Pandora has been consistently morphed with Eve in retellings and art. As with her Judeo- Christian counterpart, the way that society has approached Pandora and her story are a sort of litmus test for the way that society approaches women and their mythological and philosophical relationship to that society. It is interesting to see how Pandora's reflections in art have subtly and certainly changed over the centuries. Pandora was a popular figure in Grecian art, and generally represented as an idealized female progenitor. By the time of the Renaissance she had been sexualized and more thoroughly associated with death, and the sins and dangers of seductive Eve. Still the box takes a secondary place in the focus of the artwork. During the Protestant influenced baroque period her grace and beauty was stripped away leaving only the bloated distortion of female lust and greed behind. At that point she begins to be seen opening the box, and releasing its ills. Yet by ...

Taxonomy Essay Example | Topics and Well Written Essays - 250 words

Taxonomy - Essay Example A solution to this dilemma lies in the introduction of the PhyloCode way of naming, which could name and organize living beings on the basis of phytogeny, the evolutionary history of a species or group. With advances in modern science, it has become easier to perfectly determine the evolutionary history of a species, and species and clades can be accurately organized according to phytogeny. In this type of nomenclature, change in one part of the naming organization would not involve any widespread changes. This, coupled with its evolutionary accuracy, is being touted as the major advantages of PhyloCode by its proponents. Changing to PhyloCode from the deeply entrenched Linnean system would mean the re-definition of millions of species, something that the PhyloCode workers have not yet worked out conclusively. Global diversity catalogs will be the first to be affected by any changes that take place: while the Linnean system has the advantage in history and numbers, PhyloCode could soon be throwing the gauntlet, and the catalogs remain flexible to both.

Social Media - Assignment Example Value laden attitudes allow a social marketing manager conduct business within the existing ethical channels. The manager appreciates the value of the law in regulating good business conduct. They appreciate the role of good counsel and rely on the law for guidance.

Human Resource Management, Reflective Report Essay

Human Resource Management, Reflective Report - Essay Example Thus, this writing is both a reflection of personal experience and also a processing phase where what I have learned during the semester is linked to the situation. The definition of social responsibility has evolved over time. "Concern for business to contribute towards social prosperity has always persisted since the days of Aristotle who reckoned the need for business to reflect the interests of the society in which their operations are based" (Masaka, 2008 as cited in Solomon, 1999). As learned in the lecture, in 1953, Howard Bowen describes it as "the obligations of businessmen to pursue those policies, to make those decisions, or to follow those lines of action which are desirable in terms of the objectives and values of our society" (Bowen, 1953 as cited in Barry). I can relate this level of social responsibility to what a particular book describes as "doing at least some good" (Kotler, 2005). I can say that it has evolved over time, with an ever increasing responsibility on the part of the corporation. In the 1990's, the definition was notches higher that just doing something good for the community. Carroll says that "CSR at its core, a ddresses and captures important concerns of the public regarding business and society relationships" (1999 as cited in Barry). ... This definition, for me is a more active one. And this reflects the greater responsbility being passed on to the business industry. This definition also regards employee improvement. Thus, corporations are expected to protect and further the good of their employees. Social responsibility is always associated with the ethical standard that the company upholds. "Ethics is the discipline that examines one's moral standard or the moral standard of the society. It asks how these standards apply to our lives and whether these standards are reasonable or unreasonable, that it whether they are supported by good reasons or poor ones" (Velasquez). There are various ethical theories: the teleologial, deontological, and virtue ethics. Theological philosophy "derives duty or moral obligation from what is good or desirable as an end to be achieved" while deontological philosophy "holds that the basic standard for an action's being morally right are independent of the good or evil generated" (Encyclopdia Britannica, 2010). Working at the Dubai World Trade Centre as a Sales Manager made me experience a violation of deontological ethics. My director is very hard to work with and she only wants people to work her way. She was always rude and arguing on everything which made me feel not confident at all and as a result I decided to move to another department. With the course lesson, I just realized that I made the right decision of leaving the department as my Director does not observe either corporate responsibility or ethics. I would only be consenting to her unethical behavior if I had decided to stay. I observe many companies who are only driven my the profit motive so that they ignore corporate responsibility: both to their employees and to the society. One
