Each individual cell is covered in a hardened frustule made from silica. They are both alike in that they are both protists. However‚ dinoflagellates are a part of a group called alveolates. They are most common in marine and freshwater phytoplankton. Some are heterotrophic. Diatoms‚ on the other‚ are a part of a group called stramenopiles. They are unicellular‚ photosynthetic algae with cell walls that contain silica. Dinoflagellates are a diverse group of flagellate

tricalcium aluminate (Ca3Al2O6). When water is added‚ a number of complex hydration reactions take place. A typical idealized reaction can be represented as 2 Ca2SiO4(s) + 4 H2O(l) Ca3Si2O7. 3H2O(s) + Ca(OH)2(s). The hydrated silicate‚ called tobermorite gel‚ forms strong crystals that adhere by means of strong silicon-Oxygen bonds to the sand and aggregate (small rocks) that are mixed with the cement. Because the other product in this reaction is Calcium hydroxide‚ the mixture should be treated as a corrosive

In 1871‚ Grand Prismatic Spring was discovered and named by the Hayden Expedition for its striking coloration. Later‚ many geologists‚ traveled to the area to confirm the colors described by explorers and trappers. Grand Prismatic Spring is noted for being the largest hot spring in Yellowstone National Park and third largest in the world. The spring is located halfway between the Upper and Lower Geyser Basins. The central location provides dramatic scenery for Yellowstone’s fast visitors. The spring

Lipid and protein composition varies in tissue types. Results: When comparing liver‚ muscle‚ and adipose tissue‚ adipose tissue had the highest percent lipid and liver tissue had the highest percent protein. Conclusion: Based on analysis of the gels‚ the liver appeared to have the most variety in proteins when comparing liver‚ muscle‚ and adipose tissue. Significance: In order to determine the composition of a tissue‚ specific macromolecules can be extracted‚ quantified‚ and analyzed. ABSTRACT

Acetylation of Ferrocene 17. October 1996 Experiment #7 Introduction In this lab we will be utilizing the Friedel Crafts process of acetylation of ferrocene. Ferrocene is an atom of iron bounded by two aromatic rings. We will use some reagents that will cause the ferrocene to add either one acetyl group to an aromatic ring or add two acetyl groups to each of the aromatic rings. In order to determine how well this process had worked we employed: IR spectra analysis‚ column chromatography‚

endonucleases with gel electrophoresis. The DNA fragments‚ after cutting has occurred‚ are separated using agarose gel electrophoresis. The DNA fragments are placed in the gel‚ and an electric current is run through the matrix of the gel-like agarose. Migration of the fragments across the gel is based on the size and charge of the fragment. After the fragments have been run in the gel‚ they are stained with methylene blue and viewed on a light box. This allows the DNA bands to be viewed on the gel. Introduction
