    better grasp on the concepts of enthalpy‚ heat capacity‚ and thermochemical reactions‚ all of which were necessary for us to understand to complete the task. Paraffin wax produces more energy per gram than Ethanol based on our test results‚ and simply by the molecule comparison itself. Since Ethanol is an oxygenated molecule and already contains oxygen‚ it cannot burn at the same intensity as Paraffin does‚ since Paraffin is

    Computer Simulation of Cell Transport Mechanisms and Permeability: Passive Processes and Active Processes Introduction In this lab we will establish a difference between the two types of cell transport mechanisms and their permeability. The first type of cell transport is passive processes which are driven by concentration or pressure differences in the interior and exterior of the cell. The second type is active processes which use energy known as ATP to power the transport. There are two

    Purpose: Examine the role of the cell membrane in the cell by disrupting its function using temperature (Biology 107 Laboratory Manual 2014). This will improve the general understanding of optimal growing temperatures and the breakdown of the cell membrane Procedure: Betacyanin solution of a known concentration was diluted to create a dilution series‚ then placed in a spectrophotometer set to 525 nm. The absorbance of the dilution was used to create a standard curve for betacyanin. Discs of living

    Materials & Methods Brook trout blood was used throughout our experiment as our erythrocyte suspension‚ which consisted of ten drops of fish blood in a test tube containing 10mL of 0.7% NaCl. Eleven other solutions‚ (erythritol‚ xylose‚ monacetin‚ diacetin‚ triacetin‚ urea‚ thiourea‚ glycerol‚ ethylene glycol‚ glucose and fructose) all isosmotic but not necessarily isotonic with the cytoplasm of the erythrocyte‚ were combined with a 0.2mL of well-mixed stock suspension were added to 0.27M of each
