The Cold War Era - 1871 Words

After the end of World War II, Europe was in ruins. Between bomb damage, economic downturn, and natural disasters such as droughts and blizzards it seemed nearly impossible to restore Europe to its prior greatness. America facilitated the recovery of Europe with military and financial aid and helped prevent the spread of communism, which is proven to overtake even the strongest countries in times of distress. This aid crushed the Soviet dream of a communist Europe, which set off the Cold War. Over the next 45 years, the United States and the Soviet Union would resemble two angry women, avoiding each other at all costs and exploding into a furious rage at the first sight of the other. Many events contributed to and were derived from the Cold War such as the Truman Doctrine and Marshall Plan, the Civil Rights movement, the Space Race, the Cuban Missile Crisis, the Kennedy Assassination, and the hippie movement. Some of the most important questions that could be asked of these events ar e these: of what significance were they to the Cold War and where would the world be today if they had never happened? Lessons learned from the past affect everything about the future, and without these events, America, and even the world, would not be where it is today. The Cold War was largely characterized by how the United States treated the struggling European nations. Addressing a joint session of Congress, Harry S Truman requested $400 million in military and economic aid for GreeceShow MoreRelatedThe Era Of The Cold War Essay2000 Words   |  8 Pages The era of the Cold War was a tumultuous time where conflicts arose in many aspects of American culture and international wars waged to prevent the spread of Soviet influence over other nations.

Osmosis in Different Concentrations Free Essays

I am going to investigate osmosis when potato is placed in different   concentrations of sucrose. I am aiming to witness osmosis in 5   different concentrations of sucrose. I will use 5 varying concentrations so that I have a wider spread to compare the results,   and check that I don’t have any anomalies Prediction Osmosis  is the process of diffusion of water molecules from a weaker   solution into a stronger solution, through a semi  permeable membrane. We will write a custom essay sample on Osmosis in Different Concentrations or any similar topic only for you Order Now The tiny pores in the membrane of the potatoes will allow the water   molecules to go in and out of the potato cell, depending on the   concentration gradient between the potato and the sucrose solution. If   the  water concentration  is lower in the potato than in the sucrose   solution, then water will pass from the sucrose solution into the   potato, and it will gain weight. If there is a higher concentration of   water in the potato, then the water will go out of the potato and into   the sucrose solution, as osmosis is the movement of water molecules   from a region of high concentration to a region of low concentration,   through a semi permeable membrane. So, I predict that the higher the   concentration of sucrose, the lower the weight of the potato as water   from the potato diffuses into the sucrose solution. Predicted graph of results: [IMAGE] Apparatus * 6 test tubes * 6 different concentrations of sucrose solutions * Potato Potato cutter/core * Digital measuring scales * Measuring cylinders * Knife * Test tube racks * Tissue paper Method I will need 1 piece of potato in each tube. As there are 15 tubes I   will have to calculate how many pieces I will need altogether. I think   this would be a suitable calculation: 1Ãâ€"15=15. So, I will pierce out   some pieces of a potato using a core, and then cut 15 slices with a   knif e. Then I will measure 10ml of each of the 6 sucrose solutions   using a measuring cylinder. I will be given these different   concentrated solutions in the general laboratory. I will label the   tubes 1 to 15 and fill each one with 10ml of the solution. Tube 1-3 will have a concentration of 0 Tube 4-6 will have a concentration of 0. 4 Tube 7-9 will have a concentration of 0. 8 Tube 10-12 will have a concentration of 1. 2 Tube 13-15 will have a concentration of 1. 4 I will measure each slice on the measuring scales to identify each   potato slice with its weight before and after immersion in the   sucrose. Having measured each slice on the scale and recorded its   weight, I will then place the slices in the test tube containing the   solution for 24 hours. Then I will empty the solution from the test   tube by pouring it in the sink and remove the potatoes by hand and   place them one by one on the scale. For accuracy, I will make sure   that I wipe off any excess solution on the scale before placing each   new slice on it. I will record the weight after placing them in the   solution for 24 hours. This process will be repeated for tubes 1 to 15   and the results will be noted in a table and then plotted on a line   graph. I will make this a fair test by only varying the concentration of   sucrose and the size of the potato slices, but keeping everything else   the same. The same potato must be used for the whole experiment or   otherwise, the results would differ as the age and sizes might be   different, which means one potato might have more water in it than the   other. I will use a 10ml measuring cylinder so that I can accurately   measure the exact amount of sucrose needed. As the cylinder measures   different sucrose solutions, it has to be washed out each time I measure   another 10ml of sucrose for the next tube, because it may be   contaminated with the different sucrose’s. All the tubes will be kept for   the same time, in the same place, so that the uncontrollable   temperature would not affect the tubes separately. I will not be able to control: * Temperature – because I won’t be in the laboratory for 24 hours,   and the temperature could change in the night, or morning. *Temperature of solution- because I was not able to obtain a thermometer and I was not in the laboratory for 24 hours so it could change. * Weighing scales – because these are digital and therefore, it   produces results by itself. I will be able to control: Concentrations of sucrose – they are already measured * Time – I will do the experiment, and come back the next day at the   same time, and promptly record the results *weight of the potato- I weighed the potato slices before the experiment. For safety in the laboratory, I will be very careful using the sharp   knife which I will be using to cut the potatoes with. I will make sure   that I have an overall so that my clothes don’t get dirty if the   solutions spills. I will remember not to put potatoes or sucrose in my   mouth as they might have been infected by chemicals in the lab, which   are poisonous. I will measure the weight of the potato in grams, and the concentration of sucrose in percentage. I am expecting everything to work out well as I have a perfectly good   method but if I feel that the results may be wrong, I will repeat my   experiment. Preliminary results These are my results: This experiment supports my plan and prediction. The carrot gains   weight in normal water, and decreases weight in concentrated sugar   solutions. By doing this experiment, I believe that my method is good, and it   will work. I think I should specifically be aware of the scales,   because they alter a lot. However, this was carried out at home, so   the cooking scales may have not been so accurate, as accuracy is not   very important in cooking. Results these are my first results. They proved to be wrong. This mistake   would have been made my human. I assume that I used two different   scales, and have got all the weights jumbled up. The weight taken at   the beginning is also not correct, so I may have made a mistake right   from the start. Concentration of sucrose. | Weight before| Weight after| 0| 1. 28| | 0| 1. 33| | 0| 1. 29| | 0. 4| 1. 29| | 0. 4| 1. 27| | 0. 4| 1. 2| | 0. 8| 1. 31| | 0. 8| 1. 3| | 0. 8| 1. 3| | 1. 2| 1. 29| | 1. 2| 1. 37| | 1. 2| 1. 27| | 1. 6| 1. 26| | 1. 6| 1. 3| | 1. 6| 1. 31| | Conclusion I found out that as the concentration of sucrose increases, the weight   of the potato decreases. In water it gained 1. 26 grams, but in 1 Sucrose   solution, it lost 0. 16 grams. My prediction supports my conclusion. I have calculated the average change in weight to have a simple, clear   idea where the experiment is leading me to. Instead of having a large   number of weights, I combined them into one by averaging them. I found   the average by adding the weight gain/loss for each tube and divided   it by three. To find the percentage, I multiplied that decimal by 100. I drew a line graph, and then a line of best fit, which is sloping   downwards, negatively. This proves that the weight is getting lower as   the percentage of the sucrose concentration is getting higher. In my investigation I found a definite relationship between the 2   variables – weight and concentration of sucrose. Any increase in   sucrose concentration led to a decrease in weight. The prediction is supported by the evidence of the graph. Although   there is one anomaly, all the other results stand out and give a   straight line of best fit – exactly as I predicted. The point of   early plasmolysis is where the concentration of sucrose and potato   are even. There is no osmosis taking place at that point. As I said in   my plan, if the water concentration is lower in the potato than in the   sucrose solution, then water will pass from the sucrose solution into   the potato, and it will gain weight. If there is a higher concentration of water in the potato, then the water will go out of   the potato and into the sucrose solution. This is because osmosis is   the movement of water molecules from a region of high concentration to   a region of low concentration, through a semi permeable membrane. The up raise of sucrose is the downfall of potato mass. [IMAGE] Osmosis In osmosis, water diffuses through a semi-permeable membrane. This diagram illustrates the concentrated sugar solution, separated   from dilute sucrose solution by a selectively permeable membrane. This   has pores (holes) in it which are very small, and selects what it   wants to let through i. e. small molecules. Water molecules are very   small. Each one is made of two hydrogen atoms and one oxygen atom. However, sugar molecules are many times larger. In potatoes, the pores   of the membrane only let the water through. There is a higher concentration of sugar molecules on the right-hand   side of the membrane in the diagram, than in the left-hand side. Sugar   molecules would diffuse from the concentrated solution into the dilute   one until they were evenly spread out if there was no membrane, but   they cannot do this as the pores are too small for the sugar to get   through the membrane. Therefore, the small water molecules diffuse   into the concentrated sugar solution, to make it more dilute. This process is called osmosis. It is the diffusion of water molecules   from a place where they are in a higher concentration, to a place   where they are in a lower concentration, through a selectively   permeable membrane. Potato cells plasmolyse in concentrated solutions. This diagram   illustrates a plant cell[IMAGE] (which is similar to a potato cell) in   a concentrated solution. It will lose water by osmosis. The cytoplasm   and the vacuole will shrink. The cell membrane is semi-permeable and the vacuole contains a sucrose   solution. So when a cell is placed in distilled water (high   concentration) water will move across the semi-permeable membrane into   the cell (lower water concentration) by osmosis, making the cell   swell. This cell is called ‘turgid’. In potato cells, the cells would   increase in length, volume and weight because of the extra water in   the potato. If the potato was to be placed in a lower concentration, then the   opposite would happen, because water would move out of the cell into   the solution. If the solution is very concentrated, then a lot of water will diffuse   out of the cell. The cytoplasm and vacuole will keep shrinking, but   the cell wall will not as it is too stiff. As the cytoplasm shrinks   further and further into the centre of the cell, the cell wall gets   left behind. The cell membrane, surrounding the cytoplasm, tears away   from the cell wall. If this happens, the cell is said to be   plasmolysed. The potato will therefore, decrease in length, volume and   weight. Plasmolysis is the point where the membrane is totally detached from   its ell wall, and the potato is killed. Evaluation my experiment shows some accurate results. It concludes the experiment, and proves my prediction. My   final results were quite reliable; due to the precautions I took to make this  a fair test. The graph has a straight slope pointing downwards, which is the   clearest way to understand my prediction. All of them are not that   closely together, neithe r far away, so a line of best fit joins some   tips of the points, and causes it to go straight down. I have one anomalous result, which falls on 0 on the x axis. This   occurred in tube 5, which contained a concentration of 0. 4. Perhaps I did not   carry out that properly. These were the main problems in carrying out the experiment:- * Scales kept moving * Difficult to get out the potato from the core * Potatoes get stuck in tube. * Solution is still left after wiping the potato and the scales * Different scales * couldn’t control the temperature the point of early plasmolysis would not be valid. This is because   I have just plotted it on the graph on a line which suits my results. To prove that it is the right point, I would have to do another   experiment to find that out. The other evidence is likely to be valid, because as all the evidence   links to the results. My investigation is fair because I did not   change many things, expect the concentration of sucrose. I think that I have collected quite a lot of evidence to support my   conclusion. The result table is the main source of evidence. I could   try investigating with more percentages of sucrose concentration, the   size of the potato and have more short intervals between the sucrose’s. This would have a more spread to the results, and therefore, results   can be compared and evaluated more thoroughly. They would be very   accurate as well as reliable. As I have an anomaly, my evidence may not be extremely correct. I   would have to do more research to what I have already done (in the   conclusion) on osmosis, and see what actually happens, and see if it   occurs in plant cells all the time. If I were to repeat the experiment, I would use a very accurate scale,   so that results would come out accurately and then I would have a accurate   average. The graph will be fairly accurate. I would also make sure   that the scale and the potato slices are properly wiped. This is   because if they are not wiped, the weight would increase, and will not   be accurate. I could use a syringe or a burette to measure the 10ml of   sucrose solution, because those two apparatus are very accurate. I would do several more experiments with bigger sizes of potatoes to   obtain more evidence to support my conclusion. I will also do some   research on osmosis, and this will make me certain of my evidence if I   have many to compare with. I will agree with the majority. Overall, I am very pleased with these results and with the evidence I   have so far, that osmosis occurs when there is a high concentration   and a low concentration, both aside a semi-permeable membrane. The   lower concentrated substance diffuses through the membrane to where   there is the higher concentrated substance. How to cite Osmosis in Different Concentrations, Essay examples
