In bio lab‚ my lab partners and I did a lab experiment involving yeast fermentation. Fermentation is an anaerobic process to regenerate NAD+ to keep glycolysis active. Yeast preforms ethanol fermentation which create ethanol and NAD+. The class used six different types of sugars to determine which fuels fermentation by measuring the amount the carbon dioxide bubbles produced by the yeast. Yeast are single-cell fungi that cannot make their own food. They take the sugars in the surrounding environment

Introduction On Saturday morning of the 24th of October‚ there was report by an employee of a homicide incident on 4011 N. Central Ave‚ Phoenix‚ AZ. University Center building on the 3rd floor of Arizona State University. The victim was describe as a 24 year old Caucasian female‚ by the name of Kelly; who works as a programs coordinator for Arizona State University. The victim was working late hours as usual on a Friday night‚ she was on her office cubical. The body was found laying on the floor

______________________ LAB ____. ANATOMICAL EVIDENCE OF EVOLUTION In our studies of the anatomy and development of animals we have discovered that many living creatures that look quite different on the surface have similarities underneath their skin that suggest that they are related to each other. This is evidence that living creatures have evolved‚ or gradually changed over time. In this lab‚ you will learn about homologous‚ analogous‚ and vestigial structures and their value as evidence for evolution. INSTRUCTIONS

follows; 6H₂O + 6CO₂ C₆H₁₂O₆ + 6O₂1 There are four variables that affect the rate of photosynthesis; light intensity‚ temperature‚ CO₂ and water.2 However‚ is it possible to count in the colour of light‚ too‚ which I am going to investigate in this lab. Since the photosynthesis takes place in chloroplasts that has chlorophyll‚ the rate of photosynthesis can be affected by different colours of light‚ since the absorption of light changes within different colours. Research Question: What colour of

Laboratory Report 4: Invertebrate Animals Section: I Table: 6 Date: September 26th‚ 2013 Introduction: In our group‚ our task was to observe the selected four invertebrates and familiarize ourselves with their taxonomic levels through the organism’s mechanisms of feeding‚ motility‚ and reproduction. Our group used the prior knowledge we possessed about the Hydra‚ Rotifer‚ Gammarus‚ and Planaria organisms to complete the lab. We knew that all of these small invertebrates have a

The Evolution of Island Finches by Natural Selection The Evolution of Island Finches by Natural Selection The Evolution Lab experiment of finches located on two separate islands was conducted with purposes of evaluation and study of important principles of evaluation that include adaptation‚ natural selection process and finally the evolution process as a whole. In this study‚ "Darwin Island" and "Wallace Island" are lab environments that were used to conduct the experiment. By manipulating

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
