Journal Questions 1. Make a hypothesis about how you think the two species of Paramecium will grow alone and how they will grow when they are grown together. (Make sure you understand what a hypothesis is before you address this!) Each paramecium growing on its own will be able to grow and flourish because there is nothing stopping it or competing with it. It will be able to grow to its full capacity. When there are both parameciums growing together; one paramecium‚ the stronger of the two

Enzyme Kinetics and Protein Determination: How Enzyme Catalase Concentration Affects Reaction Rate and Determining the Identity of Unknown Proteins through Absorbance By: Alexander Mak 7238991 Partner: Yasmin Ismail BIO2137 Section A7 Corrector: Chieu Anh Ta September 18‚ 2014 Introduction: The first lab’s primary objective is to observe the different reactions rates amongst the five different catalse concentrations of parsnip. The rate at which the enzyme catalyzes increases in

In this lab we tested to see if the amount of sunlight exposed to the basil seed‚ would affect the growth. The null hypothesis for this experiment was that there would be no statistical difference between the green‚ yellow‚ and red basil seeds’ growth. Three alternate hypotheses are: If we expose the green seed to 48 hours of sunlight and the yellow seed to 24 hours of sunlight‚ then the green seed with grow more than the yellow. The opposite of this hypothesis would alternate 2. Another alternate

Lab Assessment Questions & Answers 1. What is the significance of creating Groups and adding Users to Groups? Explain. It is important to put user in groups because it is easier manager there permissions. Instead of assigning permissions to a new user every time someone is hired‚ you would just add them to the groups they need. 2. Given a scenario where there are five (5) database administrators that may periodically need access to a given system. Discuss a concept to better manage these administrators’

Analysis of Silver in an Alloy Introduction In this experiment an alloy of silver will be analyzed to determine its silver content. The silver-copper alloy will be dissolved in nitric acid‚ the silver will be precipitated as silver chloride‚ and the silver chloride will be filtered‚ washed‚ dried and its mass determined. From the mass of the silver chloride formed and the mass of the original sample‚ you will be able to calculate the percent of silver in the alloy. Because the results are

Appendix Abstract: This experiment is intended to introduce the basic concepts of the operational amplifiers and to help us better understand the relationship between the resistances and the amplifier gain. The main experiment focused on op-amps of which we have two types‚ inverting and non-inverting. With the inverting op-amps there is no current

6 – Empirical Formula of a Compound INTRODUCTION Chemical formulas indicate the composition of compounds. A formula that gives only the simplest ratio of the relative number of atoms in a compound is the empirical formula or simplest formula. The ratio usually consists of small whole numbers. We call a formula that gives the actual numbers of each type of atom in a compound the molecular formula. The numbers in a molecular formula will be whole number multiples of the numbers in an empirical formula
