Starch‚ one variable may be observed. 2. Biuret reagent will turn your skin brownish-purple. Explain why this occurs. Biuret reagent will turn your skin a brownish-purple because Iodine detects protein in a substance by changing the color to a brown or purple shade‚ and since your skin contains protein it will also change color. 3. When greasy food is spilled on clothing‚ why is it difficult to clean with water alone? Water cannot remove grease water is polar and grease is non-polar. They are

The initial length of the potato cylinders were 2cm as depicted in table two. Graph two depicts the correlation of percent change in length in different sucrose concentrations. The initial weights for the solutions lacking AgNO3 ranged from 1.0-1.7grams (Table 3). Graph three displays the correlation for the percent change

Auschwitz Concentration Camp Imagine that you were a 14 year old Jewish girl riding with your family and hundreds of other Jews and Gypsies packed into one tiny railroad car. You stop at an unfamiliar place were a man is screaming at you to get out. You have to watch your step getting out of the railcar because there are already dead people on the floor who passed on the trip here. Once you are out you are separated from your family‚ woman on one side men on the other. Kids are franticly

Proteins accomplish many different tasks‚ including structural support‚ storage‚ transport‚ movement‚ and defense against foreign substances. One noteworthy type of protein‚ called an enzyme‚ acts as a catalyst‚ speeding up chemical reactions in the cell. All proteins are composed of the same set of 20 amino acids‚ and each amino acid differs from the other only by the "R group" attached

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

of a functional recombinant fusion protein via the directional sub-cloning of an E.coli derived tyrosine phosphatase gene (wzb) into a pT5(6H)CFP mutant expression vector. Abstract: Application of fluorescent fusion proteins to the field of expression and interaction proteomics as a means of dynamic imaging proteins in vivo has allowed for rapid advancements in biotechnology research. Production of such proteins first involves the insertion of a given protein-coding gene transcriptionally in-frame

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.

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
