What pH Level Causes a Plant to Grow Best Alexis Chavez‚ Heather Nutt‚ Nguyen Phan Introduction We knew that water is normally stated as the best form of liquid to make sure plants grow as best as they can‚ but we wanted to know if causing the water to be more basic or more acidic would affect how the plant grew. Our hypothesis was that if the plant is treated with a pH of 12 then treated with another pH. Materials The materials used were three identical plants‚ that each had 4 sections that were

Period 1 10/14/12 Enzyme lab Enzymes are biological catalysts that speed up the process of chemical reactions. They are also proteins‚ and most enzymes activities occur within organism. They decrease activation energy‚ energy that is needed to start a chemical reaction. Enzymes are substrate specific substrates ending in "-ase"‚ enzymes ending in "-ase". External factors‚ such as temperature‚ pH‚ and concentration of the substrate‚ affect the enzymes activity in the lab‚ pectase and cellulase will

Roy Levin Bio 11 Lab Dr.Izquierdo Analysis of Macromolecules in Tissue Homogenates of Bos taurusMaterials and Methods The homogenates provided were made by homogenizing tissues in a sucrose phosphate buffer in a 1:20 ratio. The protein concentration in bovine cells was measured by diluting the homogenate with a 1:5 ratio; 50 microliters of homogenate and 200 microliters of water. Then 5 known protein concentration samples which were 0.4‚ 0.8‚ 1.2‚ 1.6‚ 2.0 mg/ml of bovine serum were used to

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

indicated by a very pale pink color. To calculate the molarity of NaOH‚ the following equation was used MNaOH x VNaOH = MKHP x VKHP therefore the molarity was .125 M. INTRODUCTION This lab experiment covers the preparation of standard solution and the acid/base titration. The first part of the lab is to prepare a standard solution of Potassium hydrogen per. A standard solution is a solution of known concentration‚ in which it is prepared using exacting techniques to make sure that the molarity

The 7 Deadly Sins and 7 Cardinal Virtues ======================================== Overview -------- The "Seven Deadly Sins"’‚ also known as the "Capital Vices" or "Cardinal Sins"‚ are a classification of vices that were originally used in early Christian teachings to educate and instruct followers concerning (immoral) fallen man’s tendency to sin. The Roman Catholic Church divided sin into two principal categories: "venial"‚ which are relatively minor‚ and could be forgiven through any sacrament

The Effects of pH‚ Temperature‚ Enzyme‚ and Substrate Concentrations on Benzoquinone Production BIOL 2051 June 10th 2013 Introduction Enzymes are the ultimate catalysts of living things. Enzymes are made of proteins which are structured and directed by amino acids chains. Enzymes attract and fit substrate molecules to an active site. The active site binds the substrate molecules covalently to enzyme forming an enzyme-substrate complex‚ which catalyzes

the tube with the highest concentration of yeast will produce the most carbon dioxide and will have the fastest rate of alcoholic fermentation. Results Two separate experiments were conducted to determine the effect of yeast concentration and pH level on the rate of fermentation. The first experiment involved the placement of different concentrations of yeast‚ glucose‚ and distilled water in four different tubes. Pipette pumps were placed on each tube to allow the solution to ferment
