Potter December 5‚ 2012 Lab Section 503 Abstract The over all goal of the Irresistible lab was to verify a buffer’s ability to resist changes in pH with consecutive 1mL additions of either a strong acid (HCl) or base (NaOH). The experiment entailed preparing a combination 10 buffered and non-buffered solutions and then monitoring the pH changes as a strong acid or base was added to the solution. By performing this experiment‚ it was found that with increasing amounts of buffer in the prepared solutions

in the reaction rate. To begin this trial‚ we gathered 3 cuvettes in which we added horseradish peroxidase in the following amounts; .5 mL‚ 1.0 mL and 2.0 mL. In each of these cuvettes‚ we added 2.0 mL of H2O2‚ 1.0 mL of Guaiacol and enough pH 5 Buffer to fill each cuvette to 8.0 mL with all of the materials combined. Immediately after adding the materials in each cuvette‚ we placed it in the spectrophotometer to get an absorbance reading @ 500 nm in 20 second intervals commencing at 20 seconds

of the consequences of excessive drinking. After connecting with her‚ I wanted to know if alcohol concentration in spirits would affect the cells in the body. Thus‚ I decided to test my theory by adapting a class beetroot experiment to my investigation. The aim of this experiment is to investigate the effect of alcohol concentration on a biotic cell membrane. The human body cannot live long with damaged cells because they are the building blocks of life. Cell membranes are phospholipid bilayers meaning

- Quasi Experimental Design: If the researcher lacks control over the assignment of participants to conditions and does not manipulate the causal variable of interest‚ the design is quasi experimental. o Quasi Experiments do not have internal validity because participants are not randomly assigned to conditions and the researcher may have no control over the independent variable. - Basic Confounds in Quasi Experimental Design are : o History o Maturation (Emotional‚ Physical & Psychological)
