Material Prokaryotic and Eukaryotic Cells Worksheet Provide a list describing at least three differences between prokaryotic and eukaryotic cells: 1. While Prokaryotes contain just one copy of each gene‚ eukaryotic cells have two. For such reason‚ prokaryotes are known as haploid and eukaryotic as diploid. 2. While Prokaryotes see some nonessential genes being encoded into extra-chromosomal plasmids‚ such activity is typically absent in Eukaryotic cells. 3. The own way DNA is present in each type

Lab #3: Ion Exchange Chromatography Objective The purpose of this experiment was to separate proteins on the basis of their net charge at a particular pH. In cation exchange chromatography positively charged molecules are attracted to a negatively charged column. Conversely‚ in anion exchange chromatography‚ negatively charged molecules are attracted to a positively charged column. Experimental results could be monitored in a predictable way by controlling running pH‚ salt concentration‚ and by

Khanya Ramey Tuesday Nov. 24 Intermolecular Forces Intermolecular Forces Lab II. Goal: The central goal of this experiment is to depict the intermolecular forces of four different properties of solubility‚ evaporation‚ viscosity‚ and boiling point. The reason for achieving the goal is so we can further understand solubility‚ Evaporation‚ viscosity‚ and the boiling point of liquids. III. Experimental procedures In this Lab there were four different stations to experiment with‚ my partner and

the Plant the Longest? Daniel Rivera Alfonso Pineda Mrs. Fraijo AP Biology 10 June 2012 Abstract: In this experiment‚ 8 plants will be tested. Each except one plant (which will be the control group) will receive a certain amount of water starting at 0 teaspoons of water. Each plant will receive 1 more teaspoon than the previous cup‚ so it would be increasing. For example‚ cup 4 will have 4 teaspoons of water and cup 3 would have 3. The data recorded will be the length the plant grows
