Measure and record the depth of the H2O2.Place 1 vial in the 0°C bath and leave 3 at room temperature. This is necessary because heat will destroy the hydrogen peroxide. 4. Allow the catalase and substrate to incubate at each temperature for about 5 minutes‚ then test the reaction time at each temperature by dipping a filter into enzyme at the

Evolution Lab Report Marcos Chapa July 3‚ 2013 BIO 101 Rebecca Avants The purpose of the lab I have conducted is to analyze how altering the finch’s environment would affect the evolution of the finches by isolating each population of finches from each other‚ placing them each on a different island. This influence on the species by the environment is called allopatric speciation. One population of the finches that are located Darwin Island‚ which is 1 km‚ and the other population of finches

The correlation between Firing Rate and Stretch of the slow adapting crayfish receptor for four different sets of data is represented in this figure. The recordings are taken at stretches of 2‚ 4‚ 6‚ 8‚ and 10 mm of the crayfish tail. The best fit lines for the different sets of data are as follows: Ali and Emily- Linear best fit line‚ Dave and Laura- Exponential

A. Goal and Purpose: Session 1: In this lab‚ we will achieve a simple Friedel-Crafts alkylation of anthracene. The choice of anthracene as an aromatic substrate stems from two considerations. First‚ there is a question of regioselectivity. Second‚ anthracene and its derivatives are highly visible under UV light. Session 2: In this lab‚ we will complete a partial conversion of 9-acetylanthracene using m-chloroperoxybenzoic acid (mCPBA). We will also determine by NMR‚ the regiochemistry of the

The particular conditions that had to exist for this to apply were that the population had no mutation‚ had no natural selection‚ was a large population‚ had only random mating‚ and had no migration. For the cases to follow later in the lab‚ Cases 1 and 2 exemplify Hardy-Weinberg conditions. All of the others either have selection or not enough members in the population‚ which will be the most-closely observed
