Lab 2 – Water Quality and Contamination Experiment 1: Effects of Groundwater Contamination Table 1: Water Observations (Smell‚ Color‚ Etc.) Beaker Observations 1 This beaker has water only‚ clear with no smell 2 I mixed oil in the water‚ the oil then started to settle at the top of the water. (oil is not a soluble) 3 Beaker contained vinegar and water‚ the water got a little cloudy and the vinegar smell is very strong. 4 The water and laundry detergent mix had a soapy look to it‚ water also

the Environment Week 1 Biomes and Diversity. As you have learned in the readings‚ extinction is a natural selection process. You have also read that humans are often responsible for accelerating this process. Using at least two scholarly sources‚ address whether or not we as humans should be concerned with the extinction rate. Additionally‚ discuss whether or not humans strive to preserve representative samples of all biomes on the planet Introduction to Science. Read Lab 1: Introduction

Alarms DeVry University NETW420 Alexander Davis Jun 1‚ 2014 This week’s assignment is to describe various event categories and event based transactions that are used by the Network Management System. It would be impossible to categorize all potential causes for alarms in all existing network systems however‚ understanding some common alerts and categories is essential for any network manager. Many Network Management Systems have a log and event manager that collects data

Assignment Week 4 Chapter 11 20. A parallel RL circuit has values of IL = 240 mA and IR = 180 mA. Calculate the magnitude and phase angle of the circuit current. It=√ IL^2 + IR^2= √ 240mA^2 + 180mA^2= 0.3 x 10^-3= 300mA θ= tan^-1(-IL/IR)= (-240mA/180mA)= -53° 300mA∟-53° 22. Calculate the total impedance for the circuit shown in Figure 11.38b. It= √IL^2 + IR^2= √800mA^2 + 120mA^2= 0.808949 x 10^-3= 808.95mA Zt= Vs/It= 120V/808.95mA = 148Ω θ= tan^-1(-IL/IR)= (-800mA/120mA)= -81.5= 82° 148∟82° 24

Evolution Lab BIO/101 Pooja Thakur 7-23-12 Evolution Resulting From Natural Selection INTRODUCTION The Evolution Lab simulates environmental situations to determine effects on evolution over periods of time. This lab experiments with the evolution of finches on two different islands over 100‚ 200‚ and 300 years. By manipulating parameters that influence natural selection‚ the effects that natural selection have on the evolution process can be studied. HYPOTHESES • The size

Lab Report 7: Analysis of Cereal Introduction: The objective of this lab was to consult for the FDA regarding a recently surfaced scandal involving false reporting of iron content in cereal as well as iron tablets. The makers of the cereal and the iron tablets‚ respectively‚ were allegedly reporting higher amounts of iron in their products than actually existed‚ as a way to save money but continue to provide products with “adequate” amounts of iron. The FDA needed consulting in order to analyze

Lab Report 3 In this lab‚ we will take a trip to the planetarium lab and will learn about Right ascension and declination‚ and altitude and zenith. After looking at the different points shown‚ we will log the altitude and zenith in the chart in our lab manual. Now we will look at the same points and label the right ascension and declination. Then we will learn about the easiest way to locate the star Polaris. As we started the first program‚ we answered a few questions to make sure we knew
