...The concentration versus absorbance graph yielded a straight line with R2 = 0.995. The limitation of pipetting skill can be seen clearly in the absorbance value of 1:250 solution, which slightly goes off the trendline. A possible error was that the required amount of liquid was not fully released to the tube. However, based on the linearity of the graph, the pipetting and dilution skills were acceptable. The DH5α in LB plate resulted in no bacterial growth, which indicates that some sources of error happened during the streak. Since there was no ampicillin presented, the bacteria should completely grow on the plate. One reason of error is that the loop used to streak the plate was too hot, which potentially killed the bacteria. Another possible...

...The data solute concentration of the egg was found by taking the average percent change in mass for each percent solute concentration used in the lab and putting the data into the graph(Mass vs. Solute Concentration Over 3 Days). According to the data from the class, the solute concentration inside an egg is 25.1%. The egg would be in an isotonic solution at 25.1% solute concentration. This is when the concentration outside the egg is equal with the concentration of water inside the egg. The point of equilibrium is the point at which the trendline crosses the x-axis. At this point, the egg would no longer gain or lose mass. If the concentrations are the same inside and outside the egg, diffusion will not be able to take place. All averages...

...Concentration camps in the Nazi regime * in the years of the Nazi regime there were between 400 and 1200 camps → not all death camps * before the war really began the camps were built for political prisoners of Hitler´s reign * the two main kinds of camps were: * the concentration-/work camps in which the prisoners had to do very exhausting jobs until they were too weak to work or died * the death camps where people simply were killed, mostly by gasification → in both kinds of camps there were big violations against human rights * the German industry also benefitted from the work camps because the prisoners sometimes also made things for firms * between 1933 and 1945 about 3.5 million Germans had to spend their time in a concentration camp * most of the camps were built in Poland because most of the Jews lived there and it wasn´t too far away from the eastern battlefields so it was logistically easier to transport Jews and POWs (which means Prisoners Of War) * the camp leaders decided to mark the different type of prisoners * political prisoners got red bandages; criminals got green; homosexual men pink; purple was for Jehovahs witnesses and of course yellow for Jews * the transport of the prisoners also was very dangerous for them, because in summer it was burning hot inside the small boxcars they were transported in and in winter it was freezing cold so many didn`t even reach the camp * the first camps were liberated...

...Author name: Professors name: Subject: Date: Comparison-Contrast report on the internment concentration camps placed in United States and Germany. In World War II, the people-citizens which were not needed or just migrated to the country- were detained and confined without any trail is called an Internment concentration camp. The people were prisoners and kept in very bad and extremely harsh in conditions with no rights. The present paper is to highlight the comparison-contrast of the Internment concentration camps placed by United State and Germany to imprison their own populations. Later in 1993 in Nazi Germany ,Concentration become a major source for which Nazi can easily imposed their control and across Nazi controlled Europe between 1938 and 1945 to obtain the maximum hold. The reason to setup these camps were to eliminate any opposition to Nazi by their so called enemies-people who can threat. These people includes the communists, socialist and social democrats, Jehovah’s Witnesses, homosexuals, and the so called a socials which were found in their own peoples of around 2millions in population whereas male above the age of 14, women’s and children kept in worst condition, given less water and food exposed to brutal and cruelty. They turned week and bad to continue with the deadly process. Many thousands of Jews were arrested during this period resulted bulk of the prisoners of these camps were subjected to increasingly poor conditions...

...During the time of World War II there were two types of camps made during this time. One was Internment camps for Japanese Americans and another was Concentration camps made for Jews. Internment camps may have been a harsh but they were not as bad as concentration camps. In Internment camps they wouldn't beat you for making a mistake, they let people go to school, and had good portions of meals. On the other hand, concentration camps made the prisoners work in terrible conditions, provided insignificant living conditions, and would beat and kill the Jews for no reason. Working in the concentration camp were pretty bad if you were a prisoner. The SS officer would never give any pity for the young, elderly, woman, or man. The prisoners would have to work all day till the break of dawn, in all types of weather. Let it be cold or hot, all they would have were their striped cloths. The things they worked on were war efforts, expansion of the camp and new building for the camp....

...During the reign of the Nazi regime they were able to establish almost 20,000 camps throughout Europe. With so many camps spread out across Europe each one had its own purpose. There are two sets of systems when looking at camps that were put in place by the Nazis. Each one had its own purpose; death camps were established to commit murder on a wide scale. Concentration camps were utilized for punishment or as transit between other camps. One will see the names and different types of camps that were established by the Nazis during the Holocaust. The first part one will see is the concentration camps. They played a very important role in the suppression of the Jewish people and others. Within these camps some were set as force labor to support...

...Concentration Camps during The Holocaust A concentration camp is where prisoners of war, enemy aliens, and political prisoners are detained and confined, typically under harsh conditions, or place or situation characterized by extremely harsh conditions. The first concentration camps were established in 1933 for confinement of opponents of the Nazi Party. The supposed opposition soon included all Jews, Gypsies, and certain other groups. By 1939 there were six camps: Dachau, Sachsenhausen, Buchenwald, Mauthausen, Flossenburg, and Ravensbruck. It all started in 1933 when Hitler came to power in Germany. Adolf Hitler was a very strong minded individual that liked everything to go his way, and for what he believed in. Germany was already a very racial country, and judged people strongly on their religious beliefs, and their political communities. The Nazis, also known as the National Socialist German Worker's Party, planned to murder the Jewish people. They called this plot, "the final solution." The Holocaust was a devastating time during World War Two,that changed the lives of many people all over the world. The name holocaust comes from the Greek word "holokauston", meaning sacrifice from fire. The holocaust killed many groups of people such as the Gypsies, homosexuals, Jehovah's Witnesses, the disabled for persecution, but mostly the Jews. When Hitler first gained power, he formed an advanced police and military force to smother anyone who criticized his authority. With...

...“I died in Auschwitz, but no one knows it”. These are the words of Charlotte Delbo, a survivor of Auschwitz. For many men and women Auschwitz was a time of great fear, death and despair. The Auschwitz concentration camp was a network of concentration and extermination camps built and operated by Nazi Germany in occupied Poland during World War II, and commanded by Rudolf Hoss (1900-1947). It included three main camps. All three camps used prisoners for forced labor. One of them also functioned for an extended period as a killing center. These concentration camps were made up of mainly Jewish people. An estimated 1.3 million people were sent to the camp, and at least 1.1 million died. Around 90 percent of those were Jews. As a matter of fact,...

...Westerbork was built in 1939, and was located near two towns called Westerbork and assen. The camp Westerbork was one of the 100 concentration camps used to kill Jews during the 3rd right. Over thousands of Jews were killed in the westerbork concentration camp. Some questions that are most common are. What was going on inside westerbork? How many Jews were murdered in westerbork? What type of people were in that camp? What was the environment inside the camp? The last question is we're there any people that escaped westerbork, if so how many and how? Everything the prisoners faced were unspeakable. The camp Westerbork was one of the concentration camps used to kill Jews during the 3rd right. Do you know what was going on...

...Concentration Camps The concentration camps were a major part in the second world war. Here in these camps millions died at the hands of Hitler’s ideology. These innocent people were put into camps without trial for the idea Hitler had of a “pure race’’. Origins of the Camps The first camps were originally set in Germany as detention centers for anyone who did not agree with Nazi agenda. These people were referred to as “enemies of the state” once the Nazis controlled Europe. This happened once Germans crossed Austria territory and the German Army invaded Poland. These camps were the first of the 20,000 used to cause so much death, loss, pain, and suffering (theholocaustexplained.org p?) . Notorious Camps Some of the most well known camps are such as Auschwitz, Belzec, Burgen-Belsen, Buchenwald, Chelmno, Dachau, and Dora Mittlebau. These camps were known for the death of millions of people. They were apart of the “Final Solution” program that was created for the destruction of the Jewish race. Prisoners’ Day...

...#2 Use details from the text to explain how human beings respond to the concentration camps. How do the attitudes, personalities and behavior change over time. In the story, Night by Elie Wiesel, a story is told by Elie Wiesel himself about how he and his family were captured by Nazis in 1944 and thrown into concentration camps. He recalls events that happened in that dark time period like how he and his father were separated from his mother and three sisters when they arrived at the first concentration camp, Auschwitz. Also, he talks about all of the horrible things that went on around him including the horrible conditions that he and his father had to go through. The people in the concentration camps changed throughout the story due to the circumstances they were in. The first thing that the reader notices about the people in the camps is that they had turned on each other and helped destroy each other physically while imprisoned by the Nazis. The reason for this is because they are each desperate to survive and will do anything to stay alive even if it means killing each other for food. Also...

...The Horrors of the concentrations camp is something unbelievable the crimes of the Nazi soldiers is unspeakable, they would kill, tormented and even fool around the lives of merciless people. The flesh of little children man or women burning besides each other and being able to withstand their flesh melting off their skin or even it being infuse with each other’s flesh is a crime beyond redemptions. They would force young children to adult at an early age or face the fiery cages of hell and make them work until exhaustion. The horrific devils would pile up babies the ages of 1-5 or even older and throw them into the gas chambers and face the agony of flames. Every Jewish person had to overcome this tragedy and were forced to endure the concentrations...
