Generally these stocks are often found under $1.00 but most identify them as stocks that trade under $5.00. Penny stocks cannot trade on the Dow Jones or Nasdaq but over the counter. There are several reasons why such types of stocks are so economical‚ but they can potentially be very good investments. First reason why penny stocks are so cheaper is because they signify a financially troubled firm. You

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

Abstract Photosynthesis is a food making process for algae and plants. The photosynthesis process rate varies from different wavelengths and intensities of light. This lab will evaluate the optimal wavelengths and degrees of intensity during photosynthesis when chloroplast is exposed to light. The mixtures of DCPIP with water‚ PO4 buffer‚ and chloroplast will be prepared in a number of cuvettes. The cuvettes were tested individually at different wavelengths and intensities to find the optimal rate

Introduction During the course of this lab‚ we explored whether or not certain processed foods contained Genetically Modified Organisms. Genetically modified food is an important subject in the world today. Ever since Flavr Savr came out with their tomatoes grown from genetically modified seeds in 1994 genetically modified foods has become ever more popular amongst distributors of produce (Mestel‚ 2013). The world’s population has grown by around one billion in the last decade (US Bureau of the
