This experiment was tested in Rock Hill‚ South Carolina at The Winthrop Recreational Research Complex location. Using a dissolved oxygen probe connected to a LabQuest Vernier with the software Logger Pro‚ the experiment was tested in the woods‚ wetlands‚ lake‚ and a water area near the woods. In each location there were five samples taken to be tested. Every location had the samples taken in different positions inside

between the substances and the column is determined based on the number and strength of intermolecular interactions between the two species. Substances that pass quickly through the column exhibit fewer intermolecular interactions with the column. The Vernier Mini GC uses a metal column with a nonpolar coating‚ called the stationary phase. A sample‚ consisting of one or more compounds‚ is injected into the column and is carried through the stationary phase by atmospheric air‚ which acts as the mobile phase

Introduction A key concept in evolutionary biology is that divergent selective regime will often generate and maintain some type of phenotypic diversity (Langerhans et al. 2003). This divergent selection can lead to differences in phenotypic expression either by a genetic differentiation or phenotypic plasticity (Levins‚ 1968; West-Eberhard‚ 1989: Robinson and Wilson‚ 1994; Orr and Smith‚ 1998; Schluter‚ 2000; cited in Langerhans‚ 2003). Such divergence is significant as it can influence microevolutionary

under the force of the fall without the egg cracking or popping out. The first test was to determine the average mass and dimensions of the eggs. The materials needed to conduct this section of the lab include 60 eggs‚ a scale‚ a string‚ and a caliper. In order to obtain the mass‚ an egg was placed on a scale and the mass was recorded; this was repeated for the other 59 eggs. After they were all weighed the average mass was recorded by adding up all 60 masses and dividing by 60‚ this measurement

the rate of ethanol oxidation through the LoggerPro System. This data then helped determine the kinetic rate constant‚ k‚ and the order of the reaction. First‚ the wavelength of maximum absorbance was determined using the LoggerPro interface and a Vernier colorimeter. Beer’s law was then used to determine the molar absorptivity. Finally‚ a kinetic study of ethanol oxidation was completed through the kinetic run on the LoggerPro interface. Chemical kinetics is the study of chemical reactions in relation
