substrate fits the shape of the active site‚ the enzyme will alters its shape so the active site embraces the substrate and maintains a firm grip‚ known as induced fit. This allows for great variations of enzymes. Abstract In this experiment‚ my lab partners and I tested how time effects a catalase reaction. The amount of hydrogen peroxide was recorded after the reaction for the certain time given has taken place. We used sulfuric acid to stop the reaction with the catalase from occurring. This

Aim: 1) To determine the effects of different salt concentration on the percentage of weight change in potato cubes 2) To determine the isotonic solution concentration for the potato Hypothesis: 1) If the concentration of the salt solution is higher than the concentration in the potato cubes‚ the percentage of weight change in potato cubes will be higher (positive). If the concentration of the salt solution is the same as the concentration in the cell‚ there will be no net movement of water through

Evolution Lab “Evolution by Natural Selection” The object of this experiment is to determine how changing the size of the beak of a finch will affect the population as well as the growth rate of the finch’s beak. The reason for the experiment is to evaluate evolution and how it affects the finch’s population‚ and how natural selection is always present in life. In this experiment I will show that the finch will continue to evolve until its beak has reached the optimal size for sustaining

Introduction: This lab helps further our understanding of essential principles behind diffusion and osmosis. Permeability‚ concentration gradients‚ plasmolysis‚ water potential‚ and equilibrium were also concepts that were delved into in this lab. Understanding how diffusion and osmosis works is essential to understanding biology. Each time a cell has something move into or out of it‚ some sort of principle studied in this lab is occurring. Diffusion‚ osmosis‚ and passive and active transport are

The hypothesis for this lab was that Core B will be the least flexible due to a loss in water. Unfortunately‚ my results led my hypothesis to be incorrect. The results that were received was that Core C was the most flexible‚ Core B was somewhat flexible‚ and Core A was not flexible and stiff. Core A was the most non-adjustable due to it being hypertonic which means that the total concentration of all the dissolved solute particles is greater than the other solution. Core B was isotonic meaning

balloon Bar Graph: Discussion Questions: 9) My prediction had been that the test tube with 10% of sucrose inside of it would make the most amount of carbon dioxide. My hypothesis was correct‚ and the size was gradually increasing throughout the lab. At the end it was the biggest‚ so after 1440 minutes‚ the 10% test tube was the only solution that had visible bubbles of carbon dioxide. After 1440 minutes there were no carbon

Zak Shively Environmental Science Human Demography Final Lab Report Keywords- human demography‚ environmental issues‚ economic issues‚ population‚ growth rate. Introduction- In this lab we examined data collected on 230 countries. We examined the human population characteristics and determine if environmental and economic issues impact human population. We collected data from the fields of demography‚ economy‚ education‚ health‚ geography‚ and energy. We searched for data that directly correlated

Plant Pigments and Photosynthesis Problem: We are going to separate and identify pigments and other molecules from cell extracts through a process called chromatography. We will also test the theory that light and chloroplasts are required for light reactions to occur. Background: Pigments are chemical compounds which reflect only certain wavelengths of visible light. This is what makes them seem colorful. Many things contain pigments including flowers‚ corals‚ and even skin. More important than
