How sodium chloride concentration affects the germination‚ growth and development of Brassica rapa. Osumi‚ K.‚ Nihei‚ B.‚ Takanishi‚ K.‚ Nakamura‚ C.‚ Warehime‚ R. Period 2. 03/05/17 Introduction: To have a successful germination‚ the plant seed needs a sufficient amount of water and oxygen present. Other conditions include room temperature‚ and the amount of light intake. Hydration of a seed‚ is an essential step for seed germination (Martínez-Andújar‚ 2014). Plants tend to germinate better in

For this data analysis project‚ I conducted and experiment to investigate how the concentration of an acid affects the rate of the reaction. I have set up the experiment’s equipment as shown on figure 1. As you can see by figure 1‚ I have used the reaction between sodium thisoulphate solution and hydrochloric acid (HCL) to come up with results that will help me draw conclusions regarding the effects of the concentration of the acid. I decided to use this particular reaction due to the fact that the

different pH solutions as well as to measure the absorbance of catecholase in solutions with different concentrations of potato juice and phosphate buffers. Absorbance of the enzyme catecholase was at an optimum level when pH was close to neutral. When pH was acidic or basic‚ the catecholase was less effective. Also‚ when there was a higher concentration of potato juice and a lower concentration of phosphate buffer‚ absorbance of the enzyme increased. Introduction According to Edmund J. Stellwag

Determination of the Concentration of Acetic Acid in Vinegar Lab Exercise 4 CHEM 1106 9/19/12 Purpose: Standardize a sodium hydroxide solution using a primary standard acid. Determine the molarity and the percent by mass of acetic acid in vinegar by titration with the standardized sodium hydroxide solution. Introduction: Vinegar is a dilute solution containing acetic acid. Since vinegar has a low pH‚ it can be titrated with a base. Titration is a method used in order to ascertain

Dachau concentration camp Dachau was not horror camp not like Auschwitz and Belzec that killed over 1‚700‚000 together.Auschwitz was famous for being the most horrific camps‚but it was not the first or long lasting concentration camps.Dachau camp was made of an old World War I munition factory.SS Weinrich Himmler announced the camps creation‚so people (Jews) were put on trains to arrive at Dachau.All of the many concentration camps (Death camps) made medical experiments on some of their

Treblinka Concentration Camp The Holocaust was a horrifying event. Adolf Hitler rose to power in 1933. Later they started constructing places to hold the Jewish and other people they called these place concentration camps.Treblinka was one of those camps. Treblinka was a part of Hitler’s final solution. Now you will learn about this terrible camp. “In July of 1942‚ the Operation Reinhard authorities had finished a killing center‚ known as Treblinka II.” (Treblinka) From late July and September 1942

Buchenwald Concentration Camp The Buchenwald Concentration Camp was a concentration camp that the Germans used for practically labor of the prisoners until they died or were killed by the SS. Hitler who was the Nazi leader wanted all the people that weren’t the Aryan race to die because they were not perfect. “The Buchenwald camp was located in Weimar Germany and was established in 1937. The main camp was constructed in a wooded area in the northern slopes of Ettersburg. Before the Nazi takeover

the molecules may have been moving slower. Part B: Title: The effect of salt concentration on osmosis in potato. Introduction: 1. The purpose of doing this lab is to observe the effects of various solute concentrations on osmosis in a potato. 2. During osmosis‚ water moves from the side of the membrane where they are most concentrated to the side where they are less concentrated. If the concentration is equal on both sides‚ there will be no movement. 3. I hypothesize that

Material and Methods * Osmosis : -thistle funnel tube -dialysis tubing sack -saturated NaCl w/food coloring -beaker with distilled H2O The experiments begins with the construction of a simple osmometer by obtaining pre-soaked length of tubing ‚opened and tied at the end. The tube is filled with saturated NaCl solution (with added food coloring) and the thistle is inserted in the dialysis tubing. The dialysis tubing is sealed to the thistle funnel with dental floss and placed in a beaker

Although we cannot compare the horrors of the Nazi Concentration camps to the American "Relocation Centers"‚ there are many similarities. Both of the groups of victims were of the minorities‚ and these cultures were somewhat of an enemy to the leader of their country. These groups (the Japanese in America nearly two thirds of which were American citizens‚ and the Jews‚ Gypsies‚ the Poles‚ Slovaks‚ Communists and other enemies of the state in Germany and Poland‚ many of which had served the very countries
