Erin Gaudet SCI-220-01 Title: Hair Lab Object: Analyze hair samples Procedure: Same as in lab handout Results: See attached data sheet Conclusion: This type of lab analysis is important to the field of forensic science because you could link a person to a crime. The removal of hair from the body often denotes physical contact between a victim and perpetrator and hence a crime of a serious or violent nature. Forensic scientists would find this lab useful because they would be able to determine

The objective of this lab was to recreate the color profile of a given solution. In this case‚ the solution was Powerade. The final solution should match the absorbance values at the peak wavelengths (420nm and 628nm) in Powerade. This lab was done using deionized water‚ FD&C Blue #1‚ FD&C Yellow #5‚ FD&C Red #40‚ and a spectrometer. To obtain the correct color profile‚ FD&C Blue #1 and FD&C Yellow #5 were utilized in the sample solutions. The experiment was conducted over two days; the first day

* Would yeast produce more carbon dioxide with the presence of sugar at room temperature or in an incubator? | -Observing Cellular respiration in yeast cells. | Yeast Lab Background Information: Yeast is a tiny unicellular fungus that obtains energy from outside sources (a heterotroph) mostly sugars in order to grow and reproduce. Yeast is often used in bread dough to make the dough rise. With the presence of oxygen a yeast cell creates energy by performing cellular respiration and

Meiossis and Genetic Diversity in Sordaria Meiosis and Genetic Diversity in the Model Organism‚ Sordaria. By: Katie Fiorillo BIO110 Lab TA: Lauren Smith October 30‚ 2012 A. INTRODUCTION: In this lab‚ the organism Sordaria fimicola was used to explore factors contributing to genetic evolution of sexual reproduction. These organisms are found in “Evolution Canyons‚” which occur when two mountain slopes with very different climatic conditions congregate with a comparatively small valley

the highest amount rise‚ which will show us the optimal color of light for photosynthesis. These different colors of light included blue‚ red‚ green‚ fluorescent‚ regular light‚ and classroom light. The classroom light was our control cup during the lab. Before we conducted our experiment‚ the class learned about the photosynthetic process of‚ not only spinach discs‚ but plants in general. As I did more research on photosynthesis‚ the Calvin Cycle‚ wavelengths and pigments required for a proper equation

The purpose of the lab was to measure the effectiveness of antacids at neutralizing excess stomach acid. A neutralization reaction is when an acid and a base react to form water and salt. To illustrate‚ H+ hydrogen ions from the acid react with the hydroxide ions OH- from the base. Antacids are taken to relieve heartburn or indigestion caused by excess stomach acid. For instance‚ antacids such as alka-seltzers contain baking soda which is highly reactive with acids‚ settling the discomfort of indigestion

Osmosis Lab Research Question: In this lab‚ our goal was to look at the effects of different sucrose concentrations on osmosis in potatoes. Our research question was “How do the sugar levels affect the rate of osmosis in potatoes?”. Background Information: Solutions consist of solutes dissolved in a solvent. In all living organisms there are many different types of solutes including salts and sugars. The major solvent is water. There are different concentrations of solutes in various regions
