Termite Line Width Preference by‚ Kat Lab Group: Eliot‚ Sarah‚ Nathalie September 21‚ 2012 Justification & Hypothesis During initial observations of termite behavior on a number of flat white sheets with varied lines [color‚ pattern etc...]‚ there was a reported perceived termite preference of lines. Teams were divided and free to differentiate their particular white sheet using identical ball-point pens with various lines. Some teams observed termites

LAB #1 - Assessment Worksheet 1) What does DACL stands for and what does it mean? DACL is a list of Access control entries; it defines access control for users and groups. 2) Why would you add permissions to a group instead of the individual? What policy definition do you think is required to support this type of access control implementation? When adding permissions to a group it makes it easier for a large organization and just set up the access for the departments‚ or job roles. Creating GPO

Alcohol Lab Data Conclusion Objective: The objective of this lab was to find the concentration of an unknown alcohol solution. Procedure and Data: We found the masses of 10.00 mL of each of the known concentrations of alcohol (minus the beaker mass) by placing the beaker onto the scale‚ zeroing the scale‚ and then pouring alcohol into the beaker‚ repeating for each different concentration solution. Then‚ using the same method‚ we found the mass of 10.00 mL of the unknown concentration. We recorded

The purpose of this lab was to understand that because substances have different properties‚ such as mass‚ that can be separated by chromatography. In our experiment‚ we chose 4 different color source to separate in water. We made sure that all the sources were water soluble because only polar substances will dissolve in water. We chose a black wet-erase marker‚ a red marker‚ a green marker‚ and mixed food coloring to test. The chromatography paper was split into 4 sections‚ about 2 cm above the

Enzymes are organic catalysts; where a substance speeds up the rate of chemical reactions without changing being changed by the reactions. In lab they tested this by seeing how H2O2 and the catalysts from the banana and liver react to make H2O+O2. Depending on different conditions; like decomposition of H2O2 (surface area)‚ temperature on function‚ reusing the catalase‚ reaction rate of iced liver returned to room temperature‚ and effects of pH on enzyme activity‚ to see how much O2 was released

DENSITY OF LIQUIDS AND SOLIDS by Lab instructor: Due date: Results and discussion: The purpose of the experiment was to determine the densities of the unknown liquid and solid as precisely and accurately as possible in order to identify them. It was carried out first on distilled water in order to rule out systematic errors. A 10 mL beaker was placed on a top pan balance and “tared”. The beaker was then removed and 10 mL of distilled water was pipetted into it before it was placed

Homeostasis Lab Analysis Assigned Challenge: Doorframe Look at the data for your assigned challenge. Why did the “guinea pig’s” body react the way it did during the challenge? What was happening inside of the body that you couldn’t necessarily measure or see? The “guinea pig’s” body had the reaction of soreness and weakness as time increased because the body was using more and more energy as time passed with little rest. The form of pushing that every guinea pig was excelling on the doorframe
