Changes in Physical Properties on Enzyme Activity By Alex Hoffmann First Individual Lab Report Wednesday 7:30-10:15pm 10/24/12 Meghan Duell Abstract The goal of this lab was to determine the effects of certain physical properties on enzyme activity. Enzyme activity was measured by the height of the bubbles that appeared after the enzyme was added which are proportional to the rate of the reaction when time is constant. The fact that enzyme activity is affected by physical properties such

While the text states that taking "drugs won’t enhance creativity"‚ I disagree‚ because for one‚ some of our best music comes from the major drug using era known as the 60’s‚ 70’s‚ & 80’s. All joking aside‚ I mainly just disagree with this statement in particular because I think it could have been worded a bit differently and really define what they mean by a “drug” especially because I think addiction affects everyone. What people think about when they see the word can be anything (usually derived

Derricka Joe Period 5 1 Oct.‚ 2014 Lab Experiment One: Physical Properties Lab Analysis: For our first unknown‚ we observed the color and odor of the substance. The substance was a clumpy‚ white‚ crystal-like substance and it smells like new plastic. When we tested the solubility in water it resulted insoluble and in ethanol it resulted soluble. This substance could not be tested for electrical conductivity because the water was insoluble. We then tested for the PH value and it was neutral. The

PHYSICAL PROPERTIES OF THE PERIOD 3 OXIDES These pages explain the relationship between the physical properties of the oxides of Period 3 elements (sodium to chlorine) and their structures. Argon is obviously omitted because it doesn’t form an oxide. A quick summary of the trends The oxides The oxides we’ll be looking at are: |Na2O |MgO |Al2O3 |SiO2 |P4O10 |SO3 |Cl2O7 | | | | | |P4O6 |SO2 |Cl2O

Manual Testing Faq’s What is software testing? Software testing is the process used to help identify the correctness‚ completeness‚ security‚ and quality of developed computer software. Testing involves operation of a system or application under controlled conditions and evaluating the results. Controlled conditions should include both normal and abnormal Why Management some times not serious about testing? Solving problems is a high-visibility process; preventing problems is low-visibility

Math Practice Lab Pre-Lab Questions: 1. The rules concerning handling significant figures are as follows: When dividing/multiplying The answer has no more significant digits than the number with the fewest significant digits (the least precise figure). Round off after calculations have been performed. When adding/subtracting Answer has no more places than the addend‚ minuend‚ or subtrahend with the fewest number of decimal places. Significant figures are irrelevant when adding/subtracting
