address this question: “Propose a possible explanation on why the light caused depolarization of the off-center ganglion cell?” we first have to describe the structure of the center -surround in the receptive fields of retinal. In the receptive field‚ there are cone photoreceptors that communicate with On and Off center bipolar cell and finally On and Off center ganglion cells that carry the action potential to the cortex. When light comes to the retina (eyes) it causes closing of channels in the

the functional role of amacrine cells in retinal dynamics. In this thought paper I will argue that together with the bipolar and ganglion cells‚ the amacrine cells operate in a parametric system similar to the feedback and feedforward systems found in motor control. In order to determine the role of the amacrine cells they needed to determine the method of bipolar convergence and divergence in ganglion cells. When stimulated individually‚ two different bipolar cells were able to elicit distinct post

Concentration of liquid foods is a fundamental operation in many food processes; it is completely different from dehydration. Usually‚ foods‚ which are concentrated‚ remain in the liquid state; while drying produces solid or semisolid foods with significantly lower water content. The concentration of liquid foods has three different methods; evaporation‚ membrane concentration‚ and freeze concentration. Evaporation usages gas liquid phase separation. It has the lowest capital cost and the maximum

The Dachau Concentration Camp was the first camp established in March 1933.It became the first concentration camp made by the Nazis. It was placed by a munitions factory by the city Dachau. It is nearly 10 miles from Munich‚ Germany. In the first year there were 4‚800 prisoners. The first prisoners were German Communists‚ Social Democrats‚ Trade Unionists‚ and other opponents of the Nazis. During 1937 the SS made the prisoners construct a large group of buildings on the grounds of

develop a manufacturing cell? Support your answer with examples. Cellular manufacturing is a manufacturing process that produces families of parts within a single line or cell of machines operated by machinists who work only within the line or cell. A cell is a small scale‚ clearly-stated production unit within a larger factory. This unit has full responsibility for producing a family of like parts or a product. All necessary machines and manpower are enclosed within this cell‚ thus giving it a level

Within Germany‚ there were types of camps that people could be sent to: concentration camps‚ labor camps‚ extermination camps and prisoner-of-war camps. Concentration camps were the Nazis’ way of imprisoning the Jews‚ political antagonists and other people deemed socially unacceptable of the country. If these people were sentenced to a concentration camp and did not arrive

him or her having Sickle Cell Disease. What this is is it’s a disease that is genetically inherited and it involves the red blood cells. Mutations in the HBB gene cause this disease. This disease is inherited in an autosomal recessive pattern‚ which means both copies of the gene in each cell will have mutations. The parents of offspring with an autosomal recessive gene each carry one copy of the mutated gene. The blood cells form an abnormal crescent shape (normal cells are in a disk form). The

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

These camps were still located on American soil and were not death camps. The camps were concentration camps‚ a place where they go to basically do hard labor all day. Many Japanese American families sold their homes and assets‚ there was no guarantee that their lives would continue as normal upon their return. Their homes sold for fractions of

Internal assessment on enzyme concentration Enzymes are proteins that act as catalysts and they are the most important type of protein. My aim in this experiment was to investigate the effect of enzyme concentration on the rate of an enzyme (protease) – catalyzed reaction ‚ catalysts speed up chemical reactions . My hypothesis is that the rate as reaction will increase as the concentration of protease in the solution increases so it will take less time for
