To begin with‚ a concentration camp is a place where a large amount of people such as Jews are imprisoned in a small area with no freedom‚ and this was established by the Nazis in Germany. In 1933‚ my house was raided by the Nazis and my family was sent to a concentration camp. At the concentration camp is where I met my best friend Anahi. Anahi and I were always awakened by the Kapo very rudely. The “bettenbau” is just a good opportunity for him to beat the prisoners. When we woke up‚ we had to

The great tragedy of what we know as World War two brought great danger to lots of people‚ but to not forget of what people themselves feared most‚ concentration camps. To be more specific in this case‚ the Auschwitz camps. In its time‚ it was the most effective camp of the Nazi regime. In this place‚ it consisted of three camps‚ each with their very own deadly purposes. The reasons this camp over all was the most effective was‚ history of its building‚ the day of a prisoner in the camps as well

The fluid mosaic model of the cell membrane. What is the fluid mosaic model? The fluid mosaic model is a model conceived by S.J. Singer and Garth Nicolson in 1972 to describe the structural features of biological membranes. The membrane is described to be fluid because of its hydrophobic integral components such as lipids and membrane proteins that move laterally or sideways throughout the membrane. That means the membrane is not solid‚ but more like a ’fluid’. The membrane is depicted as mosaic

The concentration of wealth is why Western Europe never fully enveloped Marxism. In the East‚ Africa‚ and South America‚ they had wealth concentrated in the hands of a very few high classes‚ whereas in Western Europe and North America it was somewhat more spread out. In the "poor" areas‚ Marxism was seen as a way to take wealth from the elites and spread it among all the people‚ and Marxism was in most cases with the overthrow and execution of the elites. In the areas where

A solar cell (also called photovoltaic cell or photoelectric cell) is a solid state electrical device that converts the energy of light directly into electricity by the photovoltaic effect. Assemblies of cells used to make solar modules which are used to capture energy from sunlight‚ are known as solar panels. The energy generated from these solar modules‚ referred to as solar power‚ is an example of solar energy. Photovoltaics is the field of technology and research related to the practical

CELL THEORY – STEM CELLS Stem cells are a large focus of study in today’s biomedical world. “They are cells that exist in an undifferentiated state‚ and transform into differing tissue types depending on what the cells surrounding them are‚“ (National Institute of Health‚ 2012). Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition‚ they also serve as an internal repair mechanism inside many tissues‚ dividing without

Investigating in the effect of ion concentration in electrolytes on the potential difference in a voltaic cell Introduction When two electrodes made of different metals are connected together in a voltaic cell‚ the chemical energy present is converted into electrical energy and an electromotive force is generated. This force‚ called the electrode potential‚ is normally measured under standard conditions‚ which is 298K‚ 1 mol dm-3 solution for the electrolyte. However when one measures the electrode
