Lab Report: Understanding Photosynthesis Gen Biology Lab Abstract: This lab was called photosynthesis: understanding photosynthesis. It is a highly complex process that needs to be broken down in many steps to understand how it works. This lab covers the big components in photosynthesis including carbon dioxide intake‚ light consumption‚ and varying pigmentation. Introduction: Photosynthesis is a huge concept to learn and understand in the field of biology. Plants have their own special

Mallory Charland February 9‚ 2015 Mutations of E. coli Lab Report Advanced Biology Deducing Mutations of the Lac Operon of E. coli Abstract: In this lab we determined a possible mutation in unique bacterial strains of E. coli by observing the proper responses of wild type E. coli Lac Operon as a control group. Mutated strains of E. coli were placed in four test tubes‚ each containing a different substance (lactose‚ glucose‚ water and lactose and glucose)

Hanging at a Constant Determining the effect mass has on acceleration Block 5 11/25/12 Purpose: The purpose of this lab is to determine the effect of additional mass added to a cart’s existing mass‚ without changing the applied force‚ on the acceleration of the cart. We will test this effect by hanging a constant mass to a cart and use a computer program‚ LoggerPro‚ to calculate the acceleration which is expressed through the

Lab Report Microbiology Introduction Bacteria can be found almost anywhere. For human life‚ some help us‚ some hurt us‚ and others are neutral. It is now known that good bacteria‚ or normal microflora‚ can reach 1014 microbial cells. This is far more than the 1013 cells that make up the human body (Tannock‚ 1995). The total number of bacteria on Earth is estimated to be around 4-6 x 1030 (Horner-Devine‚ 2004). It is important to know the extent of bacteria‚ how they live‚ and how they are

Shalacia Gilmore Fall 2012 BIO 1107 Natural Selection Lab INTRODUCTION In the 1850s‚ two scientists by the name of Charles Darwin and Alfred Russell Wallace composed the theory of evolution by natural selection. (1) Darwin characterized several claims needed for natural selection to happen‚ including heritable variation within the population‚ and the presence of more individuals than the environment can support. They also discovered that certain environments favored certain traits. These

cName: Nicholas Cassel Gen Chem 1210 23 March 2013 Blinded By the Light Abstract: In this experiment we were provided a cereal box spectrometer to observe the emission lines of noble gases and hydrogen. Based on the scale readings on the spectrometer and the Balmer-Rydberg formula‚ their wavelengths and percent error were able to be extrapolated. Based on the literature values‚ the cereal box spectrometer proved its value as a decently accurate spectrometer. Introduction: Every element

December 8‚ 2013 Soil Analysis Lab Report Intro: Soil is produced over hundreds of years through the weathering of rocks and the decomposition of organic material. Soil contains nutrients that are taken from decomposed animals and plants which turn to detritus. Nutrients such as nitrogen are added to the soil in these ways by organisms such as nitrogen fixing bacteria. Soil is important because it is the fuel to the plants that we need in order to survive and for all species to survive. Soil

Organismic Lab Lab1- Dichotomous Key Introduction A dichotomous key is a series of paired statements or questions that are used to categorize organisms with their similarities in characteristics and or structure. The word dichotomous comes from two Greek words that translate to “divided in two parts.” In a Dichotomous key each step has two choices: whether a particular characteristic is present or absent. The questions

AIM: Finding the gravitational field strength by using a simple harmonic motion of a spring and slotted masses. INTRODUCTION: When a mass suspended from a spring is displaced‚ due to the acceleration‚ kg s-2‚ from its equilibrium and released it will oscillate up and down with a kind of motion called simple harmonic motion‚ shm. The period (T)‚ time taken to measure for one complete oscillation‚ of this motion is: m/kg =

Bio Lab Report Erica Patterson September 10‚2013 Intro to cellular and molecular Biology Lab Abstract: In the Biology Laboratory Manual by Darrell S. Vodopich and Randy Moore are results to a similar experiment. The studied the hypothesis of carbon dioxide production by yeast fed sugar is not significantly different than the carbon dioxide production by the yeast fed in protein. Their hypothesis is the one that has helped formulate ours. We also will be answering the same to questions “What
