Investigate the Rate of Osmosis in Different Vegetables (Carrot, Potato, Swede, Parsnip and Sweet Potato) In this coursework experiment I plan to find the rate of osmosis in different vegetables (Carrot, Potato, Swede, Parsnip and Sweet Potato). I will measure the mass before and after the experiment to use the results to calculate the rate of osmosis, and to find trends in the vegetables. To ensure the experiment is fair, I will control all the other variables (Temperature, size of chip at 5cm x 1cm, concentration of solution at 0.2M etc.). I will repeat the experiment, and obtain averages for the change in mass. This allows a more accurate analysis to be obtained. Finally I will keep all the vegetables in the solutions for 1 hour, and then repeat this. As there are no dangerous chemicals, or heating taking place, there is no need to wear protective eyewear or overalls. However I will be using scalpels and sharp instruments to cut the chips. This requires general care to be taken, and to work in a clutter-free environment. When I am not using them I will place them away from my experiment and away from others. Any spillage of apparatus will be cleaned up directly after. To carry out this experiment, I will need the following equipment: · (2 x) Swede, Carrot, Potato, Parsnip and Sweet Potato. · (2 x) 50ml of 0.2M sucrose solution. (10ml each chip). · A razor to make the 5 x 1cm chips. · (10 x) test tubes. · Tile for cutting on. · (2 x) Test tube racks. · Safety Mat. · Stopwatch. · Sensitive scales. I plan to find the rate and trend of osmosis in these vegetables. I will have to do the experiment described above to accomplish this. To find the rate I have to find the mass change in 1 hour, and I will have the rate of mass gain per hour, for each vegetable. I predict that the vegetables will change in volume, mass, percentage change and general size during the experiment, varying for each vegetable. The biological construction of the specific vegetable will be the cause of different results. For example my own prediction is that a sweeter tasting vegetable must have more natural sugar in it, hence more osmosis will occur, and the vegetable will have a larger size gain, of water. Due to the vegetables being in 0.2M sucrose solution I predict they will all gain mass, but varying concentrations of sugar will alter the results. For my results, I ... ... middle of paper ... .... This anomaly is disregarded because the results were so close together that it would have been possible for the scales to pick up excess wind or someone may have lent on the table at the same time, (Swede-0.25g, Sweet Potato-0.235g). The results were within 0.015g of each other. This would explain the anomaly. When I repeated the experiment the results varied from the previous experiment. This shows that it was extremely easy to make mistakes in the experiment, and that I may not have cut the chips to an exactly identical size. This just proves that the data was unreliable, but still gave an idea of the experiment, and what the results should have been. To improve the method, I would have used a machine to cut the chips to an exact size, along with making sure that all the measurements were correct and accurate. I would also leave the chips in the solution for a longer time, as to obtain better results. This would also reduce risk of errors and anomalies. To extend my work I can do other experiments of a similar nature. For example I could vary the sizes of the chips to see if that affected the results, and also change other variables, which I kept constant in this experiment.
IX was established many people thought that women were more concerned and involved in getting married, and having children rather than continuing their education. Until the early 70's, many colleges and universities were reluctant to admit women into their student body. Fortunately, the unfairness in admissions of higher education for females that was prominent prior to the early 70’s is less common. Women now receive undergraduate and graduate degrees at a significantly higher rate than before the adoption of the Title IX's statutes. It's more common today for women to take professions that were more commonly dominated by males. Title IX is an important legislation because it helps increase women's access to higher education, protect against sexual harassment, and help increase the number of female athletics
...g Title IX’s coverage to protect those who laid claims against institutions for sexual discrimination from retaliation (“Court’s”). Another amendment made to Title IX came in 2009 as a result of the Fitzgerald v. Barnstable School Committee trial. This one is fairly straight forward and is one of the most recent amendments made. In 2009, parents of a kindergartener filed complaints against the school when their daughter came home and accused a third grade boy for making sexual comments towards her on the bus (George 53). The court found that victims of sexual discrimination or harassment could now sue the specific individual who committed the act, as opposed to the entire program or institution (George 42). The amendment also provided some suggestions to aid institutions in these cases, helping them avoid paying damages to plaintiffs for one person’s act (George 42).
Title IX is a law that requires equality of genders in every educational program funded by the federal government. It is called the “living, breathing law” because it’s been the subject of court cases, amendments, and reviews. (NWLC)
Osmosis in Potato Tubes Osmosis: Osmosis is the movement of water molecules through a semi-permeable membrane from a high concentration to a low concentration. Diagram: [IMAGE] [IMAGE] Aim: To see the effects of different concentration of sugar solution on Osmosis in potato tubes. Key factor: In the investigation we change the sugar solution from: 0%-10%-20%-30%-40%-50% this is the independent variable; the dependant variable is the change in mass. Prediction: I predict that all the potato tubes in pure water or low concentration sugar solution will swell because water enters their cells by osmosis.
Imagine, if you will, that you have just found out you have a terminal medical condition. Doesn’t matter which one, it’s terminal. Over the 6 months you have to live you experience unmeasurable amounts of pain, and when your free of your pain the medication you’re under renders you in an impaired sense of consciousness. Towards the 4th month, you begin to believe all this suffering is pointless, you are to die anyways, why not with a little dignity. You begin to consider Physician-Assisted Suicide (PAS). In this essay I will explain the ethical decisions and dilemmas one may face when deciding to accept the idea of Physician-Assisted Suicide. I will also provide factual information pertaining to the subject of PAS and testimony from some that advocate for legalization of PAS. PAS is not to be taken lightly. It is the decision to end one’s life with the aid of a medical physician. Merriam-Webster’s Dictionary states that PAS is “Suicide by a patient facilitated by means (as a drug prescription) or by information (as an indication of a lethal dosage) provided by a physician aware of the patient’s intent.” PAS is considered, by our textbook – Doing Ethics by Lewis Vaughn, an active voluntary form of euthanasia. There are other forms of euthanasia such as non-voluntary, involuntary, and passive. This essay is focusing on PAS, an active voluntary form of euthanasia. PAS is commonly known as “Dying/Death with Dignity.” The most recent publicized case of PAS is the case of Brittany Maynard. She was diagnosed with terminal brain cancer in California, where she lived. At the time California didn’t have Legislative right to allow Brittany the right to commit PAS so she was transported to Oregon where PAS is legal....
In the end, Frederick Douglass was a very successful and smart African American. Infact of him being a slave back then. Most slaves couldn’t receive education due to slavery and racism.
Title IX has drastically changed the lives and the quality of the lives of women. The law deals with schooling and sports, but the reach of it extends much further. Women are not told that they are equal, and then receive unequal benefits anymore, and they have the same opportunity of education as men. Although Title IX is not the only reason for the status of women today, it helped greatly in the process.
Title IX states that "No person in the United States shall, on the basis of sex, be excluded from participation in, be denied the benefits of, or be subj...
Douglass an individual who was born into slavery was separated from his mother at an early age, from my point of view without my parents specially my mother I would not be where I am today. Even though Douglass was separated from his family and in a way, did not have sense of family he did not let himself to be broken by this. He was a smart child who was determined to enjoy life to be best he could, even though at an early age all he understood about a slave life was misery. As he matured and grew, he started to noticed that there was more than just slavery but he was eventually broken by the harsh treatment of slavery. As Douglass

The approach of physician-assisted suicide respects an individual’s need for personal dignity. It does not force the terminally ill patient to linger hopelessly, and helplessly, often at great cost to their psyche. It drive’s people mad knowing they are going to die in a short period of time, suffering while they wait in a hospital bed.
Title IX is a law passed in 1972 that requires gender equity for boys and girls in every educational program that receives federal funding (U.S. Department of Education, 2007). No person in the United States shall, on the basis of sex, be excluded from participation in, be denied the benefits of, or be subject to discrimination under any educational programs or activity receiving federal financial assistance. – From the preamble to Title IX of the Education Amendments of 1972 (U.S. Department of Education, 2007). The actual Title IX document was based on 10 key areas: (1) access to higher education (2) employment, (3) athletics, (4) career education; (5) education for pregnant and parenting students, (6) employment learning environment, (7) math and science, (8) sexual harassment, (9) standardized testing and (10) technology (titleixinfo.com.2011). Title IX legislation has been subject to over 20 additional reviews and proposed amendment revisions due to the different interpretations and lifestyle changes that present themselves in their various court cases.
Title IX is attributed to have an important effect on the number of women in higher education. Richard W. Riley, former U.S. Secretary of Education, asserted that, "The great untold story of success that resulted from the passage of Title IX is surely the progress that has been achieved in education. In 1971, only 18 percent of all women, compared to 26 percent of all men, had completed four or more years of college. This education gap no longer exists. Women now make up the majority of students in America's colleges and universities in addition to making up the majority of recipients of master's degrees. Indeed, the United States has become a world leader in giving women the opportunity to receive a higher education." (25 Years of Progress, The U.S. Department of Education, p.online). Many universities and colleges did not allow women entrance before the legislation (The Legislative Road to Title IX, The U.S. Department of Education, p. online). Title IX has had a huge positive outcome on the availability of higher educational opportunities for women by making sure that women are given equal opportunities to men that help them graduate from and achieve academic success past secondary levels of schooling. This has logically resulted in an increased number of women in more specialized and higher paid jobs. Title IX is effectually changing the face of the American workplace by giving women the opportunity to learn, compete, and surpass men.
The confines of ignorance and both physical and mental abuse kept slaves from self discovery and rebellion. Frederick Douglass provides the journey of life as a brute to a free man. Frederick Douglass’s new identity included having a wife, a job of his own, a house, and the goal to reach out and help the people that were still stuck in slavery. From the rock bottom life of a slave he built himself up and became a successful
Osmosis in Carrots Background Osmosis is the diffusion of water from a dilute solution to a more concentrated solution through a partially permeable membrane, which allows the pass of water molecules but not solute molecules. [IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE][IMAGE]If a cell is placed in a less concentrated solution water enters because the less concentrated solution will have a high concentration of water than the inside of the cell. Once the cell takes in maximum water the cell becomes turgid. If the cell was to be placed in a high concentrated solution, water would leave the cell because the cell would contain a low concentrated solution. So in the low concentrated solution there will be a high concentration of water and in the high concentrated solution there will be a low concentration of water.
