The Road Not Taken an analyis Essay Example For Students

The Road Not Taken an analyis Essay Do not follow where the path may lead Go instead where there is no path and leave a trail. Robert Frost Everyone is a traveler, choosing the roads to follow on the map of their continuous journey, life. There is never a straight path that leaves one with but a sole direction in which to head. Regardless of the original message that Robert Frost had intended to convey, his poem, The Road Not Taken, has left its readers with many different interpretations. It is ones past, present and the attitude with which he looks upon his future that determines the shade of the light that he will see the poem in. In any case however, this poem clearly demonstrates Frosts belief that it is the road that one chooses that makes him the man who he is.

It is always difficult to make a decision because it is impossible not to wonder about the opportunity cost, what will be missed out on. There is a strong sense of regret before the choice is even made and it lies in the knowledge that in one lifetime, it is impossible to travel down every path. In an attempt to make a decision, the traveler looks down one as far as I could. The road that will be chosen leads to the unknown, as does any choice in life. As much he may strain his eyes to see as far the road stretches, eventually it surpasses his vision and he can never see where it is going to lead. It is the way that he chooses here that sets him off on his journey and decides where he is going. Then took the other, just as fair, and having perhaps the better claim. What made it have the better claim is that it was grassy and wanted wear. It was something that was obviously not for everyone because it seemed that the majority of people took the other path therefore he calls it the road less travelled by. The fact that the traveler took this path over the more popular, secure one indicates the type of personality he has, one that does not want to necessarily follow the crowd but do more of what has never been done, what is new and different. And both that morning equally lay in leaves no step had trodden black. The leaves had covered the ground and since the time they had fallen no one had yet to pass by on this road. Perhaps Frost does this because each time a person comes to the point where they have to make a choice, it is new to them, somewhere they have never been and they tend to feel as though no one else had ever been there either. I kept the first for another day! The desire to travel down both paths is expressed and is not unusual, but knowing how way leads on to way, the speaker of this poem realizes that the decision is not just a temporary one and he doubted if I should ever come back. This is his common sense speaking and acknowledging that what he chooses now will affect every other choice he makes afterward. Once you have performed an act or spoken a word that crystalizes who you are, there is no turning back, it cannot be undone. Once again at the end of the poem the regret hangs over the traveler like a heavy cloud about to burst. He realizes that at the end of his life, somewhere ages and ages hence, he will have regrets about having never gone back and traveling down the roads he did not take. Yet he remains proud of his decision and he recognizes that it was this path that he chose that made him turn out the way and he did and live his life the way in which he lived. I took the road less trvaeled by and that had made all the difference. To this man, what was most important, what really made the difference, is that he did what he wanted, even if it meant taking the road less traveled. If .

Diffusion and Osmosis Lab Activity Essays - Membrane Technology

Diffusion and Osmosis Lab Activity Essays - Membrane Technology Diffusion and Osmosis Lab Activity Dr. Alan Rizzo IB Biology SL Year 1 October 10, 2013 Diffusion and Osmosis Lab Activity Activity A Glucose concentration Time (min)Observation Glucose stripLugols solution (Starch indicator)Dialysis tube of glucose starch solution 0Test pad has green color, indicating 300mg/dL of glucose.Dark and transparent amber with tints of red. It is not uniform: contains dark spots of red color. Solution has translucent, pale, milky, cloudy white color. 3Test pad is yellow with a tint of green in various spots, indicating the concentration of glucose as being less than 100mg/dL. 15Test pad is very dark with green color, indicating glucose concentration of 1000mg/dL.Transparent, paler yellowish brown with tints of lighter shade of orange.Solution becomes less translucent and less milky. Data collection Conclusion and Evaluation From this experiment, it is perceived that the size of molecules matter when passing through a semi-permeable membrane. The dialysis tube initially contained only starch and glucose molecules. But because it was submerged in Lugols solution that had higher concentration of Iodine for a period of time, as a result of diffusion, indicator solutions molecules that consisted of iodine naturally moved from a region of higher concentration to a region of lower concentration. On the other hand, glucose and starch are both macromolecules that are large in size. Glucose molecules are smaller, and some of them were able to diffuse through the dialysis membrane into Lugols solution while starch molecules were too large and remained in the dialysis tube. In the end, molecules in Lugols solution and glucose molecules were present outside the tube. Inside the tube, there were Lugols solutions molecules, remaining glucose molecules and starch molecules. The concentration of all solutions is balance d inside and outside the dialysis tube consequently. This experiment showed one systematic error. The dialysis tube, after being in amber-colored Lugols solution for a long time, should turn darker or black in color. Becoming darker in color indicates the diffusion of Lugols solutions molecules that pass through the membrane. In order to clarify this error, more trials of this experiment should be conducted on several dialysis tubes, which will cause the data to be less anomalous and more accurate. Activity B Potato sticks and salt concentration Introduction Hypothesis: The longer the time period potato sticks are left in salt solution, the more flexible they will become as most potato cells will be in the state of hypertonic solution. Potato sticksObservation - Effects of salt solution on potato sticks) BeforeAfter Rigid, bendable, rough Snaps broken Pale yellow Average length of 3 cmExtremely flexible Paler shade of yellow Does not snap broken when bent Average length of 2.9 cm Data collection Conclusion The experiment proves my hypothesis correct. This experiment causes potato cells to shrink as a result of osmosis diffusion. Initially, the concentration in potato cells is high, while the concentration of water in salt solution. Osmosis, movement of water molecules from a region of higher concentration to a region of lower concentration, caused water molecules within each cell to diffuse out into the salt solution in order to create equilibrium of concentration both in and outside the potato cells. Consequently of the decrease in amount of water in each cell, the flexible cellular membrane was pulled in and more wrinkled-like; the cell shrank in general. With cells now shrank and less rigid, potato sticks became more bendable and very flexible. Activity C Red onion cells and 2% NaCl solution Introduction Hypothesis: If red onion cells are exposed to 2% NaCl solutions drop longer, cell membranes will shrink further, as a result of becoming hypertonic solution. Conclusion This experiment demonstrated the process of osmosis and supports my hypothesis. By using the microscope, it was noticeable that red onion cells cell membranes were shrunk after a drop of 2% NaCl solution was put on the coverslip. It was the result of osmosis, which is the movement of water molecules from a region of high concentration to a region of lower concentration. When NaCl solution was dropped on the coverslip and entered red onion cells, the internal environment of each cell is more concentrated in terms of water. Consequently, the water molecules left the cells for the external environment, which had lower concentration of water molecules in order to create equilibriums inside and outside of the cell. The cell walls did not shrink as they serve as
