In my BIO 102 lab I have learned about the Microscope and Lab Safety‚ Sensory Organs (Eyes and Ears)‚ The Human Blood and Circulation‚ and Respiration. Once I first started this class this semester taught us about the Microscope and Lab Safety. According to google online dictionary a Microscope is an optical instrument used for viewing very small objects‚ such as mineral samples or animal or plant cells typically magnified several hundred times. We used this instrument to look at different types

Introduction The function of the aggregate supply and aggregate demand model is to give details on how real growth domestic product and the price level are determined and how they interact with each other‚ this is as according to Parkin et al (2013:632). As defined by Parkin et al (2013:636) the quantity of real growth domestic product demanded is the overall volume of final goods and services produced in South Africa that people‚ businesses‚ governments and foreigners plan to buy. The quantity

Enzyme Lab Introduction/ Abstract An enzyme is a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. They are mainly made up of proteins and can tremendously speed up reactions. E. coli ( a bacterium) has about 1‚000 different types of enzymes floating around in its cytoplasm at any given time. Enzymes can be used to join and even break up molecules as shown in the diagram below. (1)

TITLE Homeostasis –Urine Analysis OBJECTIVES 1) To know know the various urine components 2) To detect abnormal constituents 3) To get a brief introduction on clinical biochemistry INTRODUCTION Homeostasis mechanism of human body will regulate the osmotic pressure of the blood. This function is carried out by the kidneys‚ that will filter blood and produces urine through three stages: ultrafiltration‚ reabsorption and secretion. The end product of the process will produce urine

Plasmid Grant Zarrinmakan‚ Berkley Kruschke‚ Erika Lawrence. Wed/Fri‚ D-Block‚ 12-January-2015 Introduction Transformation is the genetic alteration of a cell resulting from the direct uptake of exogenous DNA from its surroundings. By doing this lab‚ we will answer the essential question: What influences transformation efficiency? Although there are many possible influences‚ our hypothesis is that plasmid has a positive influence. To test this hypothesis‚ we will set up an experiment in which we

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
