Paper chromatography is a useful technique for separating and identifying pigments and other molecules from cell extracts that contain a complex mixture of molecules. The solvent moves up the paper by capillary action‚ which occurs as a result of the attraction of solvent molecules to the paper and the attraction of solvent molecules to one another. As the solvent moves up the paper‚ it carries along any substances dissolved in it. The pigments are carried along at different rates because they

The most fundamental cause for Miss Julie’s downfall would be her cognitive dissonance as a result of conflicting values infused by each of her parents. First‚ Julie acquired her emotional aspect through her commoner and feminist mother‚ therefore acted less femininely and boldly revealed her sexual desire. In contrast‚ she inherited aristocratic status and rational aspect from her father‚ which gave Julie a notion of pride and honor with classist attitude. These contrasting identities would have

Week 4 Checkpoint Detecting Plagiarism Q: Response to Results The results of the paper‚ Lab Courses Go Virtual‚ came back with 98% similarity of plagiarism. This result defiantly exceeds the maximum amount allowed in regards to plagiarism. If I were the student‚ I couldn’t look my instructor in the eye or in this case respond to any correspondence with a clear honest and complete reason as to why I would have done something so deceitful as to copy some else’s work.

CONCLUSSION and RECOMMENDATION Computers are becoming in our life and one cannot image life without computers in today’s world. If you go in any establishment computers are all places. We can say that this kind of innovation assist each and every one of us uses to experience a well-situated life. Thus‚ we students also need to use different gadgets‚ devices or modern technologies in order to have an easy going life at school. A manual computation in a school won’t give us a quick computation.

typically symbolizes are considered human’s unacceptable behavior. Pigs are often depicted as a character who’s unclean‚ greedy‚ and conceited; being the displeasing character in stories or in religions. Marianne DeKoven‚ who wrote the article “Guest Column: Why Animals Now?”‚ explains how anthropomorphism removes the animal’s real purpose in this world. “All literary representations of animals no more form a unified or even meaningful category than do those of women or the working class.”(363) She

curvature in the neck‚ upper trunk and lower trunk is normal. Humans need these spinal curves to help the upper body maintain proper balance and alignment over the pelvis. However‚ when there are abnormal side-to-side (lateral) curves in the spinal column‚ we refer to this as scoliosis. Scoliosis occurs most often during the growth spurt just before puberty. While scoliosis can be caused by conditions such as cerebral palsy and muscular dystrophy‚ the cause of most scoliosis is unknown. Scoliosis

5.05 Mixtures and solutions Lab report Ink Chromatography Chromatography is also used to compare and describe chemical substances. The chromatographic sequence of sorbed substances is related to their atomic and molecular structures. A change in a chemical substance produced by a chemical or biological reaction often alters the solubility and migration rate. With this knowledge‚ alterations or changes can be detected in the substance. Chromatography serves mainly as a tool for the examination and

Experiment 3: Isolation of Chlorophyll from Spinach and Chromatography Performed February 14th and 16th By Kyle Herzog Organic Chemistry 344 Section 807 Spring 2012 Objective: The purpose of the experiment is to extract pigments from spinach leaves and separate them by column and thin layer chromatography‚ determining Rf values for the pigments. Equations: Rf= Distance travelled by a given compound/Distance travelled by a solvent solution 1. Crude- 4.25/5.5= 0.773 2. Carotene-

Comparison of Extended Column Test (ECT) and Propagation Saw Test (PST) Introduction: Stability or “Instability” Tests are an important tool for determining the likelihood of a slope to produce an avalanche. Many different tests have been developed over the years – each with their own strengths and weaknesses. These tests provide a way to safely apply stress and deformation to a slope that is steep enough to slide (usually 250 or steeper) and observe and quantify the results. These results
