Jane Smith Miss Darr AP English – Night 23 August 2013 Chapter 1 1. Describe Moshe the Beadle. Explain his relationship with the Jews of Sighet‚ particularly Eliezer. Moshe the Beadle is poor and not a local Jew. He is foreign and now lives in Sighet. He’s very shy but the people welcome him with open arms despite him being strange at times. He teaches some Kabbalah to Eliezer. 2. How does deportation change Moshe? How do others’ feelings toward him change? When he comes back

The effect of increasing substrate concentration on rate of an enzyme reaction. Enzymes are biological catalysts that lower a reactions activation energy making possible many of the reactions needed for life to exist. Enzymes have a high specificity which have been explained by many theories such as Fischer’s lock and key. Currently the most widely accepted theory is the induced fit hypothesis proposed by Koshland in 1958. This hypothesis solves some of the problems with the Lock and key theory

The aim of this experiment was to investigate the effect that a glucose concentration has on the rate of fermentation. This was done by adding a variety of different glucose concentration into a test tube‚ siting in a water bath. The carbon dioxide would be collected in the test tube and therefore would measure the rate of fermentation. The results parsley supported the hypothesis that‚ “If the glucose concentration increases‚ the rate of fermentation increases‚ therefore the more carbon dioxide

Lab activity 1: Effect of temperature‚ concentration‚ and pressure on equilibrium Introduction Our ongoing discussion has been on systems at dynamic equilibrium: for a reversible reaction‚ the rate of the forward reaction is equal to the rate of the reverse reaction. What happens if equilibrium is disturbed? In this lab activity‚ we are going to examine the effect of changing reaction conditions on the position of equilibrium. Part I: Effect of temperature We will consider the equilibrium

doing‚ these are the factors I could change: * The concentration of the enzyme * Increase the temperature * Increase the PH I have chosen to investigate how the concentration of the enzyme affects the rate of reaction. I expect that the more concentrated the enzyme the faster the reaction time will be. Changing the concentration of the enzyme will affect the rate of the reaction. I predict that as we increase the concentration of the enzyme the faster the rate of reaction will be

Practical report: Determination of concentration using a standard curve Introduction Spectrophotometer is an instrument that confirms the measurement of specified wavelength of light that passes through medium. The measurement of light absorbance by a solution is also done with spectrophometer. Absorption spectrum Spectrometers are mainly and widely functional in identifying the components of solutions that helps determine the components’ concentrations. Compounds are experimentally identified

During World War two‚ the nazis captured and imprisoned many people who did not fit into their desired Aryan race or disagreed with their beliefs. During the prisoner’s time alive in concentration camps‚ some were subjected to horrific experiments. Many of them either died or were left disfigured due to these events. Many of the tests were to benefit the lives of Nazi soldiers. However‚ some doctors performed the test without a proper reason behind it. An example of how the Nazis felt about the Jews

probably have heard of the concentration and internment camps that withheld many innocent people from the outside world during World War II. These camps both had the same concept with trapping people inside a designated area and forcing them to live. They also have a major difference between how they treated their prisoners. Because the prisoners trapped inside these camps weren’t seen as equals‚ they were undoubtedly mistreated. Although both camps were similar‚ the concentration camps were made to torture
