should show a red/brick color after being placed in boiling water for three minutes‚ but if a negative reaction occurs we will get blue color or no change at all. Another test that we were introduced to was the iodine test‚ which is used to detect starch. A positive reaction would result in a blue/black color‚ where as a negative reaction would be an amber color. Then in order to find the remaining agents (peptide bonds) we used Biuret’s solution‚ a violet color is produced when there is a positive

Direction and concentration gradients Bradley Benton ABSTRACT In this experiment‚ we will investigate the effect of solute concentration on osmosis. A semi‐permeable membrane (dialysis tubing) and sucrose will create an osmotic environment similar to that of a cell. Using different concentrations of sucrose (which is unable to cross the membrane) will allow us to examine the net movement of water across the membrane. INTRODUCTION A major determinant of diffusion in a biological system is membrane

When‚ and why‚ was Chelmno created‚ and where was the concentration camp located? What was the treatment like for the Jewish people who resided at the camp‚ and for the workers who occupied the camp. Where is Chelmno at now‚ and what happened to the camp? These are all simple question to answer‚ In the beginning of the war‚ the Chelmno concentration camp was one of the Nazi’s‚ and Hitler’s‚ first concentration camps. Chelmno was also one of the first camps to use gas vans. The not-so-well-known

Enzymes are important components of life‚ facilitating reactions that are necessary for an organism to live. Enzymes can be very specific to what environment they function best in1. Numerous environmental impacts were tested for the enzyme peroxidase which catalyzes the decomposition of hydrogen peroxide. The basic decomposition reaction was carried out first without any environmental alterations. The hypothesis for this reaction was supported. The enzyme caused the amount of absorbance increase

of an enzyme-controlled reaction. How do these factors affect the chemical structure and properties of the enzyme. Many things can affect the rate of enzyme activity. The temperature of the enzyme‚ the pH of the solution‚ the concentration of the enzyme‚ substrate and the product. Also‚ another affector is the number of competitive and non-competitive inhibitors. As I cannot explain them all‚ I have chosen to explain the effect of temperature and also the effect of inhibitors on enzyme activity

SOLUTION AND CONCENTRATION A solution is a homogeneous mixture‚ made up of a solute dissolved in a solvent. Ex. In a water (aqueous) solution of sodium chloride‚ the sodium chloride is the solute and the water is the solvent. Solute – the component that is dissolved or is the least abundant component in the solution. Ex. Sugar‚ salt Solvent – the dissolving agent or the most abundant component in the solution. Ex. Water Common Types of Solution State of Solution State of Solute

In order to keep the caravans away from Turkish villages and prolong marches‚ indirect routes were deliberately chosen.

Did you know the Concentration camps were divided into different categories. I will explain about the forced labor camps‚ reformatory camps‚ Pow camps and extermination camps. I will explain about the harsh living sition that millions of people that were put though. In detail I will explain their day-to-day life was like and way the Nazis developed this camp system. Concentration camps were horrible in WWII Because of their purpose and the function. The concentration camps was made by

Experiment 2: Estimation of protein concentration Introduction Protein assays are designed to measure the total protein in a solution. Protein assays are quantitative if the protein to be assayed is available in sufficient quantity such that one is able to use it to create a standard curve. If this cannot be achieved‚ then a standard protein‚ such as albumin‚ may be used for a standard curve with the understanding that the results on the unknown protein are semi-quantitative. Since most proteins
