Lab 6.C Hypothesis: If enzyme activity is affected by the pH of a solution‚ then the enzymes will experience the greatest activity at a pH of 6. Variables: Independent Variables Dependent Variable Controls Four different pH values (10‚ 7‚ 6‚ and 3) Change in color of the solution The amount of potato extract‚ pH solution‚ and catechol used (1 cm +/- .1cm) Size of the test tubes Amount of time allowed for the catechol to sit with the potato extract and pH solution (20 minutes with 5

Variables: Independent variable: the mass of the beans Dependent variable: the different types of beans Control: The beans Purpose: The purpose of the lab is to find equal measurement of each type of bean. After you find the mass of each bean you need to find the relative mass of each bean. The navy bean will have the smallest relative mass. You will need to wear safety goggles and a lab apron and wash hands after the lab is finished. If you drop any beans pick them up immediately to prevent

rate is the speed of the change in either reactants or products over a period of time. General kinetic rate equation is: Where [A] and [B] are the concentration of the species in the reaction. The variable k is the rate constant‚ which is a function of time and catalyst presence. The variables m and n are the order of reaction for their respective species concentration. The higher the value of the reaction order the larger the effect of that specie’s concentration on the rate of the reaction

Chapter 7 Notes Page 1 Variable Costing Absorption As we have seen in previous chapters‚ when you manufacture your own inventory‚ the cost of that inventory includes all of the costs associated with running the factory that produces the inventory. Generally‚ no part of the factory cost is expensed. Instead‚ it is capitalized as the cost of the inventory produced. It is only expensed when the inventory is sold. At that point the cost of the inventory becomes Cost of Goods Sold. This system is

Difference between Variable & Absorption Costing When it comes to managerial accounting‚ the way that information is presented can affect decision-making for a business. In a manufacturing environment‚ companies can use absorption costing or variable costing when accounting for the costs of products produced. While these methods are similar‚ they have some key differences that can impact the company. Absorption Costing * Absorption costing‚ also known as full costing is a method by

Collisions in Two Dimensions Abstract: This lab was conducted to investigate the theories of conservation of momentum and kinetic energy in different types of 2D collisions. In order to do this‚ both an elastic and inelastic collision was conducted on an air table with pucks. A video was taken and analyzed to determine velocity‚ allowing for future finding of momentum and kinetic energy values. By finding these‚ it was possible to determine which kind of collision took place. With low values of

People had become extremely dependent on technology. Nowadays‚ people have laptops‚ eBooks‚ etc. Life has come way easier than before because of all this new technology. People are just commonly fascinated in all that has been created in today’s world that makes the one task little bit easier by the push of a button. People cannot imagine their lives without technology. People start feeling anxious when hand phone and laptops are not with them. Dependent too much on technology has caused people

Within the languages of the world lie an abundance of linguistic tools to express meaning and ideas. This inherent variability in is a fundamental and defining characteristic of language. Individually‚ each language possesses a spectrum of various registers which branch from the substrate and each are assigned distinctive linguistic features and guidelines. The processes by which formal and dialectical languages are produced and applied are defined by many varying conditions. As speakers‚ we call
