Candy Chromatography: What makes those colors? The point of doing this project is to use paper chromatography to see which dyes are used in the coatings of your favorite colored candies. Chromatography is a technique for separating mixtures. Chromatography can be used to separate specific components from a complex mixture‚ based on molecular size or other chemical properties. It can also be used to identify chemicals‚ for example crime scene samples like blood‚ drugs‚ or explosive residue. Highly

Case Study: Newsflash! Transport Proteins on Strike! 1. What is the meaning behind the PHOSPHOLIPIDS’ chant? Phospholipids make up most of the cell membrane‚ in a phospholipid bilayer. Phospholipid molecules form two layers‚ with the hydrophilic (water loving) head facing the extracellular fluid and the cytosol (intracellular) fluid‚ and the hydrophobic (not water loving) tails facing one another. The cell membrane is constructed in such a way that it is semipermeable‚ and allows oxygen

Characterization While many people in this world embrace their culture‚ there are certain individuals who struggle to define what their culture is‚ and who struggle to find themselves. In Alice Walkers “Everyday Use‚” each character individually represents a different aspect of who they are‚ and of what they believe in. The characters Maggie‚ Dee‚ and Mama all represent a different aspect of life‚ which helps to contribute to the overall theme of heritage within a family. Ever since the family

Chromatography Experiment of the Drosophila Eye Pigmentation Pathway Introduction: How can the use of chromatography help explain single gene mutations of the drosophila melanogaster bio-synthetic pigment pathway? This experiment was meant to help connect the mode of inheritance with different eye color mutations and pinpoint where they occur in the pigment pathway. The drosophila eye color is a result of two bio-synthetic eye color pathways‚ this is expressed as a trait or phenotype‚ a multigene

Protein Article Research Kristen Roberts Immunity is the ability of a body to resist infection or to counter the harmful toxins produced by infecting organisms (Martin‚ Hine 2008). Antibodies and white blood cells are defensive cells and substances‚ these things produce an immune response. If such an encounter such as‚ bacteria‚ viruses‚ fungi and parasites occur can make the macrophages engulf the microorganism and secretes cytokines and chemokines. This attracts immune cells to the infected

In Alice Walker’s short story‚ “Everyday Use”‚ we see 3 variations of characterization. The most prominent characterization is of Mama. She is described as a masculine woman‚ rejecting the traditional role of a female. Throughout the story you can see what Mamas views on heritage and tradition are. Walker’s purpose in writing this story is to creatively give a visual on how important family relationships are‚ and how the different between members brought to light over time can create conflict.

Gas Chromatography: Purifying alcohol Introduction The goal of this lab is to understand the principles of chromatography by purifying alcohol using fractional distillation. Running standards with gas chromatography we were able to see and calibrate our data to find not only how much ethanol our alcohol attained but also what a mixed unknown sample contained. Chromatography is a way of being able to separate substances in solution that can help not only identify the analytes (the studied
