During WW II, the Nazis and the Imperial Japanese both inflicted horrible cruelties upon the people whom they placed in their various camps, the main difference being that the Nazis intended that no one in the camps would survive, while the Japanese were not specifically trying to kill everybody in their camps, although they did mistreat them terribly.
The Trail of Tears was when Cherokee Indians were taken from there homes by the government, and the Japanese Internment camps were there because the government didn't trust Japanese people.
The Japanese Internment Camps were America's version of Concentration Camps for US citizens of Japanese ancestry. However we felt the term Interment was more "polite" than Concentration to describe the camps. There was little difference between them and Nazi Concentration Camps of the time, except that they were not also frequently Extermination Camps where inmates were deliberately executed en masse as in the Nazi camps.
The Japanese internment camps were sort of like special prisons for Japanese-Americans during World War II. The camps weren't very nice, nor was being imprisoned in them, but at the same time, the internees were not tortured or otherwise severely harmed. Still, it's not one of America's proudest moments. They were intended to keep Japanese-Americans on the West Coast from assisting the Japanese military if it ever invaded the USA. The Nazi concentration camps were special prisons that were initially meant to function a lot like the aforementioned internment camps. However, the Nazis didn't wait long to start doing terrible things to the internees, such as using them as slave laborers, performing medical experiments on them, or simply executing them. Unlike the Japanese internment camps, the Nazi concentration camps were intended primarily to get rid of any people that the government didn't like- Jews, Russians, Poles, Romany, homosexuals, political opponents, and so forth.
The Internment camps for Japanese-Americans were structures and the Holocaust is a concept. There were camps within the Holocaust designed and used to imprison certain sections of society, much like the internment camps in the USA. But what went on in these camps was very different.
A concentration gradient refers to the gradual change in concentration of a substance over a distance, while a concentration difference simply indicates the variation in concentration between two points. In essence, a concentration gradient describes how the concentration changes across a space, whereas a concentration difference highlights the contrast in concentration between specific locations.
It is unclear whether you mean the Japanese internment camps in the USA or the POW camps in Japan, as comparisons are often made with both, so i will answer both questions: Nazi concentration camps were camps for civilians, designed to keep certain sections of society out of the way, as were the Japanese internment caps. The really big difference between the two was how people were treated, in the Nazi camps people were used as slave labour and killed, in the American camps people were allowed to live with their families and suffered no greater persecution. Japanese had not signed the Geneva convention (despite what 'Bridge on the River Kwai' said), so felt no obligation to treat the POWs well, in fact they viewed soldiers who surrendered as unworthy, so the felt justified in mistreating the POWs. The really big difference is that they were military institutions.
There is no comparison at all!
A concentration gradient forms when there is a difference in concentration between one place and another.
The concentration gradient is the difference in concentration of a molecule between one area and an adjacent area. This difference creates a gradient that drives the movement of molecules from an area of higher concentration to an area of lower concentration, a process known as diffusion.
There is no exact number assigned to the difference between the higher and lower concentrations. However, the establishment of a concentration differential is essential for both diffusion as well as osmosis.
A gradient forms when there is a difference in concentration between two places. This gradient drives the movement of substances from areas of higher concentration to areas of lower concentration through processes such as diffusion or osmosis.
I think that depends on your school. In my school, a consentration is taken in conjunction with another language under the heading "Modern Languages" and a major is just studying the language or culture or both.
