Investigating Osmosis in Potato Tissue :: Papers

Investigating Osmosis in Potato Tissue Aim To estimate the concentration of sucrose in potato tissue. Hypothesis ========== I believe that the potato tissue that has been in the hypotonic (0.1M sucrose) solution will be more turgid than before, while the tissue in the isotonic (0.3M sucrose) will be similar to its previous state. The tissue that has been in the hypertonic (0.5M sucrose) should be far more placid than it was before. This is because of osmosis - water diffusing in and out of the potato tissue cells. Apparatus =========  · 1 potato tuber  · 1 cork borer  · 1 ceramic tile  · 1 scalpel  · Paper towels  · 6 boiling tubes  · 1 marker pen  · 0.1M, 0.3M, and 0.5M sucrose solution  · Access to an electric balance  · 1 funnel Method ====== The volume of each boiling tube was calculated, and then 2 tubes were half-filled with 0.1M sucrose solution, 2 tubes were filled with 0.3M sucrose solution, while the final 2 tubes were filled with 0.5M sucrose solution. Then 6 cylinders of potato were cut from the tuber using the cork borer. These were then all cut down to 20mm in length using the scalpel. They were then dried with the paper towel to remove excess water before being weighed on the electric balance. The weight of each was recorded. They were then all immersed in the solution in the boiling tubes, and the tubes were labelled using the marker pen and then lids were put on. They were then left for 24 hours in a moderate temperature before being taken out and dried using the paper towels. They were then weighed on the electric balance and the final mass was recorded. The cylinders were then gently squeezed to determine the condition of the potato tissue after osmosis - very firm (turgid), firm, or soft (flaccid). The percentage difference between the mass before and after the experiment was then calculated, and the

This Comfortable Cage Called America :: Personal Narrative Essays

This Comfortable Cage Called America    My brothers have a cage in which they keep two iguanas.   I'm sure these creatures were born in captivity, and I assume they will die in the same cage they are in now.   It's not a bad cage.   There are quite a few square feet for them to run around, there is a stick they can climb up and down, there is a heat rock they can relax on, and they have everything they need to survive at their clawtips.   They don't even need to hunt for their meals because their meal tickets (my brothers) provide them with four square meals a day.   They can see outside their cage, but have no idea what it would be like to live outside.   I often wonder, however, what would happen if we were to set these two animals free in what would be considered a natural habitat for most iguanas in the wild.   Would they be likely to adapt in no time at all, or would they look for a nice place with four glass walls and a stick to play on?   And how could this story about two lizards, even if used metap horically, apply to us as a race?   We are responsible for our entrapment within four similar glass walls, yet we are not aware of them.   Inside of a cage called America we sit, and though we have a great view of the rest of the world, that's all it is-a view.   If we could somehow find a way of recognizing and breaking out of this comfortable cage called life, we would be more capable of coming together as a human race and putting an end to a division so obvious that terms such as "first world" and "third world" are created to define the differences.   Although I will incorporate the use of a few references, the main section of this essay will focus on my own experiences of life in another country which, in its own way, was another world.      Ã‚  Ã‚  Ã‚   I was taught little in school or home about cultures and people other than my own.   Was theple other than my own.   Was there a reason I should have learned about a less productive people in some remote country?   There was nothing wrong with the land of the free and the home of the brave, and whether or not I was culturally diverse was of little importance in my life-until I went to live in a different country.

Argumentative Paper †Abortion Essay

Abortion is a huge problem throughout the United States. It needs to be stopped. Abortion can be defined as the deliberate termination of a human pregnancy. Abortion is not justified for three reasons. One, having an abortion is taking away an innocent life. Two, there are not many reasons that make it okay to kill an unborn baby. Three, every child needs to be given a chance to live, because every child is wanted. To begin with, having an abortion is taking away an innocent life. It’s not the baby’s fault that it was brought into the world, and it should not be punished for that. Every month, more lives are aborted than the total amount of lives taken in the Vietnam War. Statistics show that 1,500,000 to 2,000,000 babies are aborted annually. The bible tells us that God hates hands that shed innocent blood. God views the unborn as human and precious. He says, in Jeremiah 1:5 of the bible,† Before I formed thee in the belly I knew thee, and before thou camest forth out of the womb I sanctified thee, and I ordained thee a prophet unto the nations.† (Wilson) Next, there are not many reasons that make it okay to abort a child. People may give the following reasons that they think make it ok to have an abortion: rape, deformed children, or that the mother can’t afford a child. In the case of rape, abortion is an act of violence that kills a living human being. The circumstances surrounding the conception do not change this simple reality. In the case of deformed children, there are children of all ages, and adults too, who are alive today, and are living with diseases and disabilities. These physical limitations do not make them any less human. If the mother can’t afford the child, there is a solution. There are many crisis pregnancy care centers that offer financial assistance to pregnant women, and then afterwards they will place them up for adoption if necessary. (â€Å"Poverty, rape, disability†) Finally, every child needs to be given a chance to live his/her life, because every child is a wanted child. Whether the parent wants the child, there are still many people in the world who would love to adopt a child. The National Council for Adoption states that there are â€Å"between one and two million infertile and fertile couples and individuals who would like to adopt children.† There are also a large number of couples whose hearts are ready to adopt terminally ill babies, including babies with AIDS. Adoption is a responsible, helpful solution to abortion. Although the mother still has to carry the baby for the duration of her pregnancy, she is also able to give the baby a chance to live his/her life. No child should be given up because every child is a wanted child. (Gans) In conclusion, adoption is a huge problem in the United States. It is not justified for many reasons. Having an abortion is taking away an innocent life. There are not many reasons that make it okay to have an abortion. Every child in this world is a wanted child. Whether the parent of the child wants the child there is another option other than abortion. Adoption is a great option that saves a child’s life.

The last supper -movie satire analysis

After having buried 10 conservationists , the students have a garden full of tomatoes proving that † conservationists serve great as fertilizers†(NOT) and since that in life they served no good to the society from the liberals point of view, in death they can. The students invite the guests with an already planned ending for all of them: death. They are in continuous disagreement with them in order to find something that they , n turn, see as wrong and reason the death of the guest , this taking some of the guilt off their shoulders and considering it a â€Å"good gets for society' .At the slightest â€Å"counter-idea† they hurry the dinner and get to the exciting part of it by using phrases such as: â€Å"it's time for dessert â€Å". Len the movie ,this is seen in the scene where the anti ecologist gradually considers their point of view as well and starts rethinking; confused of him agreeing to the libertarian point of view, and used to Just having their gues ts poisoned, the group of students does not break the â€Å"Sunday ritual† and assures the guest( by saying † you are entitled to your own opinion†) , who comes back to his conservationists point of view.This goes to the original argument :insignificance of life. As the movie progresses the students kill more and more people ;slowly not taking into consideration their status in society , Just their â€Å"closed-minded† ideas. The director stops introducing the guests by their names as they will eventually die;instead, continues by defining(l want to say it in a different way) them by their causes and slowly Just shows the piles of soil that were once their guests.The students decide a matter of life and death by either last questioning the guest : â€Å"if you were in a bar with a guy called Doll Hitler , would you kill him to save all those life's or would you let him live†? Or â€Å"it's 4 to 1 . He lives. † This again, shows the insignifica nce of life and how little they care for the others and their fate. RACISM (DISCRIMINATION AGAINST BLACKS ) From the very beginning ,Luke is the one who initiates the idea of having â€Å"the deadly dinner† ,even though his colleagues are reluctant.He is also the one to have suggested not to call the police ,and instead Just hide the murder . While he starts off as the most rational in critical situations, he becomes the most irrational ,cruel and â€Å"quick-tempered† ; he is also very sarcastic throughout the movie ( † keep them in the kitchen barefoot and pregnant† he says to a sex offender they have had as guest) . By the end of the movie he loses control and gets to the point where he is about to kill one of his own mends.THE LAST SUPPER (RELIGIOUS REFERENCE) In the movie, the 5 students are supposed to take the place of the apostles and the guests are Jesus, who is going to be sacrificed. The characters are also given names of apostles Dude,Pauline,Ma rc,Luke and Pete) The difference is , the roles are reversed, while the apostles are meant to spread the good word of â€Å"Jesus† to other people, they kill him. This could also mean that the students represent only two apostles :Judas(who betrayed Jesus) and Peter (who denies he knows him ) ;While Jesus is aware of his scarification , the guests aren't .The guests are also served â€Å"very good food† as it will be their last meal . Unlike most movies where good always wins over bad in the end, â€Å"The last supper† ends by having Norman -(the very conservatism celebrity that is present in short scenes throughout the movie ,watched and critiqued by the students ) killing the 5 students with their own weapon and later describing himself as a â€Å"humble ,humble servant† in his presidential campaign. Why is it being satirized? ) I believe that the director is trying to say that both the right and left wing /wingers can become evil/ harmful when taken to the extreme :extreme conservationists ( the guests) and extreme liberalizes(the students) 2) Another problem I think the director meant to point out how easily people lose their life's over different causes (like those mentioned in the movie: homosexuality , anti-ecologist, racism). This makes me wonder ,† Is it really worth it to die for it or to take a life? And â€Å"When can you say it was right for you to decide that someone's existence isn't important to the society anymore ? † . This argument can be evidenced by history itself. Situations where people have died and been killed because their opinions or way of being did not correspond to the majority are many, hence Stalin's saying : † If you are not with us , you are against us. â€Å"Another example is the time of â€Å"The inquisition† (an example Ewing Galileo Gillie's scientifically proven idea that the earth revolves around the sun did not correspond to the original statement . N order to avoi d imprisonment , he was forced to deny his statement. ) 3) Throughout history , â€Å"blacks† have always been seen as the â€Å"bad guys† with bad intentions . Len the movie , they have chosen the â€Å"head of the plan† ,a black , meaning to make fun of the concept and the stereotyping . 4) â€Å"Good doesn't always win in the end , especially in the real world† is what the directors expressed through their last scene . Corrupted people become the leaders of our countries. Is it effective?In my opinion, â€Å"The last supper† is a good movie, with a well-planned plot that is rather a continuous sarcastic response to certain topics such as : discrimination, the unnecessary deaths of people and intolerance. This film made me question my own tolerance of different views; it also made me think of how ,as a libertarian myself do I change the world without imposing my own views. Some minus points , from my perspective, are the repetitive scenes in the dining room of the guests and the students and the rushed through scenes that take place in the middle of the movie.

Guidance and Discipline Issues in the Early Education Essay

Children who come from a lower economic background have a much greater disadvantage than other children. Early childhood represents a particularly important time to target children’s risk of behavior problems through proper guidance and discipline. There is a great need for preschool classrooms where processes are able to support a young child’s emotional and behavioral development. Low-income children who attend a lower quality preschool do show an emotional and behavioral adjustment and are placed at a substantially greater risk in the long run (Magnuson, & Waldfogel, 2007). This shows us that even though the intentions to teach the child where there, we may be doing more harm to the child then help. It is imperative to learn whether interventions that target social-emotional development in preschool can avert the risk of higher behavior problems among low-income children while also supporting their emotional, behavioral, and academic adjustment. Children who are exposed to a wide range of psychosocial stressors such as living in a poor neighborhood are at a greater risk for developing emotional and behaviors issues. These children also have minimal access to mental health services (Fantuzzo et al. , 1999). Early childhood is quite possibly the most important time to target children’s risk of behavior problems. Evidence regarding the onset of behavior problems as early as toddlerhood is mounting. With this evidence, it suggests that the earlier the intervention is conducted there is a better chance for a more positive result. The goal is to reduce the early childhood behavior issues while preparing the children for school readiness. In order to do this, preschool classrooms have become increasingly important. Approximately 67% of young children in the United Stated are enrolled in center-based or non-relative care prior to enrollment in kindergarten (Innes, Denton, & West, 2001). If children from ethnic and minority groups are less likely to be enrolled in a beneficial program, the gap in education may be widened. Children who spend less time in beneficial programs and attend lower-quality programs do not receive the benefit that preschool is intended to give. The experience of a high quality preschool may narrow the racial and ethic gaps, if children from minority groups are more likely to be enrolled and spend more time in them. When it comes to preschool programs and ethic gaps in school readiness, there is shown to be a difference in racial diversity of school readiness. It is shown that a child who attends a quality center or preschool program is more ready to learn upon entering school. These children are much more likely able to know what is expected as far as behavior in the classroom. These children are given the skills in classroom guidance that they needed prior to entering elementary school. However, since not all preschools are of high quality and there are differences in the type and quality of programs, not all children are receiving the benefit. According to Magnuson and Waldfogel, black children are more likely to attend preschool than white children, but may experience lower- quality care. Hispanic children are much less likely that white children to attend preschool. (Magnuson & Waldfogel 2005) The best estimates of the effects of early childhood care and school readiness note that these programs enhance children’s cognitive development and academic skills.

The Crucible Diary

I cannot believe that John Proctor! Why has he chosen his sniveling wife over me? I am more of a woman than Goody Proctor. Goody Proctor does possess of the qualities needed of a good wife. She is naà ¯Ã‚ ¿Ã‚ ½ve, simple, and talented. However, I possess the qualities of a lover. I am intelligent, able, and adventurous. To be blatantly honest, I think any man would be lucky to call me his wife. Diary, why am I good enough for any man, but I am not good enough for the man I desire? I know why. It is because I want a married man. Diary, do you agree that John should leave Goody Proctor and marry me? Do you think I am better than she is? I believe I would be a much better wife. Think about it, if Goody Proctor were good to John would he have come to me? I do not believe so. To me, it is the duty of a wife to keep her husband satisfied and in line. However, if John had not strayed from his wife, John would have never sought me. If John had never sought me, I would have never felt love. John may have sought me, but he is still married to Goody Proctor. She is keeping me from my John. Because of that, I loathe her. There is not a single thing in the world that she can do that I cannot. She can cook, clean, and pray. I can do all that, and even more! I am willing to do anything to be with my John. All I want is to be with him. Diary, do you have any ideas to cause the end of the Proctor marriage? I believe I do. I will receive vengeance on Goody Proctor. I will claim that Goody Proctor is a witch! It is a brilliant idea. When Salem village hears of this, the village people will believe it and order her hanging. It is genius! I would be overcome with joy to see the body of Goody Proctor hanging. At last, I would be with my beloved John! Oh Diary, I know it is a terrible to wish death upon someone, but in this case, Goody Proctor's death is necessary in order for John and me to be together. Diary, I need to be with John. He loves me and I love him. I know we are destined to be with one another. Diary, I thank you for listening to me. You have always been a faithful friend. Besides John, no one seems to want to listen to me, Oh, how I miss my John! Oh no, I fear Uncle has arrived home. I must go. He will be expecting me. I promise I will write again soon. Love, Abbey

Applying Student Development Theories to Experiences of Interviewees

Introduction As a practitioner of student affairs, use and understanding of student development theory is an important element in our responsibility. We have to learn how to apply different theories to specific situations where our students appear on the university campus. Student development theory is also important to understand why students can act in their own way. The theory of student development can be defined as a way to improve the ability of a student to grow after enrolling in a higher education institution, the ability to grow, or the ability. Heggins and Jackson (2003) focuses on applying student development and transition theory to understand the experience of Asian international students at university. After interviewing 28 Asian international students, I found that Asian students participating in the survey are seeking family and social support to deal with problems and challenges. Researchers recommend that teachers, resource centers, and student services provide cou nseling opportunities to enable Asian international students to make better use of existing social support networks. International Higher Education Education and Learning 2009, Vol. 22, No. 3, 374-385 http://www.isetl.org/ijtlhe/ ISSN 1812-9129 The purpose of this paper is to apply two development theories to development events in the respondents' life by questionnaire. The purpose of this article is to achieve a clear identification of the events occurring in respondents' lives. It will be discussed throughout the article, that is, they go out of the family for the first time. After that, in this paper, we outline the method of creating questionnaires and managing questionnaires. Then this article will continue to introduce Albert Bandura, the first development theorist. A brief discussion on the second development theorist Urie Bronfenbrenner and his ecological theory follows. In this article, we analyze respondents' responses in detail and explore the relationship between two the orists Bandura and Bronfenbrenner. Finally, this paper reflects the continuing relevance of the application of development theory and their development theory in the own experience of the interviewee by summarizing and summarizing all the information discussed in the thesis It is aimed to do. A respondent of this case study was a 28-year-old woman born in Victoria, Australia. In this case study, the development event she was asked was the first time she left the family. This is an important development event, but it will not give pressure or discomfort to respondents during the discussion. The questionnaire was created based on the theory of Albert Bandura and Urie Bronfenbrenner. Since these questions are aimed first to obtain some historical information about respondents,
