Jeanine Campa Biology 101 10/20/2010 Ecology-Interspecific Interactions Lab Intro: Ecology is the study of how organisms interact within their environment. Every species interacts with its surroundings‚ whether it’s within their populations‚ community‚ ecosystem‚ etc. In this lab‚ we will be comparing two different species and how they grow alone as well as together‚ in the same environment. More specifically‚ in this lab‚ we will be dealing with one of the most important ideas in ecology‚ the

Collision Lab Simulation Purpose: To study elastic and inelastic collisions in one-dimension. Background Information: Momentum: is a measure of mass in motion. It is the product of mass x velocity. Conservation of Momentum: in the absence of external forces‚ such as friction‚ the linear momentum of a system remains constant. Procedure: 1. Open web browser and go to the site: http://phet.colorado.edu 2. Click “play with sims”‚ then “physics”‚ and then “motion” 3. Find the “Collision Lab” 4

Effects of Enzyme Catalysis of H2O2 by Catalase Report by: Timmy Lin (#269164729) October 17‚ 2011 Mr. Rienzi AP Biology Problem: Measuring the effects of Catalase enzymes on hydrogen peroxide decomposition. Measuring the rate of the reaction when hydrogen peroxide and Catalase are mixed at the same ratio for different time (10‚ 20 30 60 120 180 360 seconds). Background: Enzymes are biological catalysts that carry out cellular metabolic processes with the ability to enhance the rate

In each station there was a positive and a negative control. If the substance was the same as the negative control then it was negative. If the substance was the same as the positive control than the substance is positive. In the first lab we did the Paper Spot test‚ one would have had to apply the substance on a cardboard like paper. If it looked oily it was the biomolecule called lipid. The result of test one was it stayed the same‚ it did not turn oily and was clear. Next was the test

Part 1A Analysis questions: 1. How many “chainobeads” was your enzyme able to make per minute in the 0 – 15 second interval? Our enzyme was able to make 6 chainobeads in the 0-15 interval. 2. How many “chainobeads” was your enzyme able to make per minute in the 60 – 120 second interval? Our enzyme was able to make 49 chainobeads in the 60-120 intervals. 3. Did your enzyme’s rate change over time? How does this compare to a real enzyme? The enzyme’s rate did change over time. This compares to a

structures. However‚ this means that once the structure of the enzyme is denatured and changed‚ the functions will most probably modify as well. In nature‚ this happens when the temperature and concentrations of different components are altered. In this lab experiment‚ we will be doing an in-depth research of exactly what happens to the enzymes‚ when it happens‚ and why it denatures the way it does. b. Hypothesis Materials and Methods a.
