Science Lab- Determining the Most Effective Antacid Robby Grewal SNC2D0 Introduction: Heartburn is a form of indigestion by acid digestion it affects many people worldwide. A solution to defeat heartburn is to take an antacid. An antacid is medicine which neutralizes your stomach acidity. In this experiment‚ we will be using three liquid antacids which are Phillips Milk of Magnesia‚ Life Brand Milk of Magnesia and Diovol plus AF and determine which one is the most effective at neutralizing

bacteria will be one of the following: Enterococcus faecalis‚ Staphylococcus saprophyticus‚ Escherichia coli‚ Enterobacter aerogenes‚ Proteus vulgaris‚ Salmonella [I assume typhimurium]‚ or Shigella [either flexneri or sonnei‚ we used both in our lab during the semester]. Procedure {and observations}: Observe bacterial colony morphology. {Colonies are large‚ beige or cream-colored‚ with irregular borders.} Prepare two slides for gram staining and viewing under a microscope. {Either my gram-stain

The PLGAh and PLGAh+Q carrier was tested by these assay for rate of apoptosis in the in Michigan cancer foundation (MCF-7) cell lines. The control was the normal cancer cell lines without any PLGAh and PLGAh-Q carrier. The PLGAh carrier was tested in assay in two different concentrations which was found above 1.5 µg and 3.0 µg. The summation of early and late apoptosis was just 8 % in concentration

one outlier that was strange was the one paper towels. Only 14 of the 15 seeds germinated in that group. The difference that we could observation was the healthiness of the plants. IV. Conclusion Paragraph 1 Recap (Evidence): The purpose of our lab was to see if the amount paper towels would affect the germination of the seeds. My hypothesis was‚ if I increase the amount of paper towels‚ then the germination rate would increase too. We observed the petri dishes in class and we would add 2 ml of

This lab activity will go over environmental factors that affect the folded structure of proteins. We used a raw egg and noted the changes that happen when there were changes in temperature‚ pH levels‚ and salinity. Five eggs were cracked open and placed into different bowls with different solutions placed into each bowl. What we looked at was the process of denaturing of proteins seeing how it affected the composition of the raw egg between the yoke and white portion. My hypothesis for this experiment

Meiosis and Genetic Diversity in Sordaria 979554296 Biology 110 Lab Introduction: In Israel there exists multiple spots in the mountains called Evolution Canyons‚ which are all located between a southern facing slope (SFS) and a northern facing slope (NFS). What’s particularly interesting about these locations is that despite the two slopes being on opposite sides of a small canyon‚ they exhibit extremely contrasting conditions. The SFS receives multiple times the UV radiation from the sun
