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

Experiment on Cellular respiration of Mung Beans Seeds with the Effects of Temperature Introduction: ATP is generated from aerobic respiration from the use of biosynthetic pathways. Glycolysis is where respiration starts in the cells and produces ATP‚ NADH‚ and 2 pyruvate molecules from the oxidation of six carbon carbohydrate and glucose. Even if oxygen is there or not‚ enzymes are mediated in the cytoplasm. The electron transport chain‚ chemiosmosis‚ and aerobic respiration use NADH molecule

Abstract The enzyme peroxidase has been shown to break down H2O2. Enzymes are known to increase the rate at which a chemical reaction occurs. We looked at factors that affected the breakdown of hydrogen peroxide. These effects are the different temperatures and pH levels the enzymes were placed in. We found that the optimum‚ or best condition‚ temperature for the enzymes tested was about 22 degrees Celsius. The optimum pH level for the enzyme was 7. Introduction Enzymes are biochemical that catalyze

Dylan McFarland 9/15/14 Honors Chemistry Richardson Lab: Measuring the Density of Pennies Pre-Lab Questions: 1. The equation that relates density‚ mass‚ and volume is: density = mass / volume. 2. All substances have unique densities‚ so if you are able to find the density of a substance‚ you can properly identify it. 3. We measure irregular-shaped objects with the use of water displacement because it would be nearly impossible to get the exact measurements

Light Microscopy Lab Lab write-up 1 Parveen Rajper Biology 101 Principles of Biology 1 September 29‚ 2012 Introduction: The light microscope helps see the microscopic world that the naked eye cannot see. If there were no microscopes in the world‚ than it would be very difficult to understand the many particles that surround the living world. The purpose of this lab experiment is to become familiar with a microscope. It is hypothesized that it will be difficult

CHM1032L pre/post lab instructions Preparation is a key to success in this lab. For this reason‚ you are required to thoroughly read through the experiment information presented in the lab manual‚ and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab‚ I will not allow you to enter the lab and you will receive

Safety Concerns in the Laboratory Safety goggles must be warn at all times during a lab session. This is very important because they protect your eyes from harmful matter such as chemicals‚ glass‚ and fumes. It is very important to note that they must be goggles and not glasses. Safety glasses may protect the eyes from flying debris and splashes but may not protect the eyes from gas fumes or splashes from underneath. Also‚ wearing contact lenses in a chemical laboratory without proper coverage

Utilizing the Lab Results PS2200 - Criminal Investigation Unit 04 Assignment 01 As the lead homicide investigator for this case I had recently learned that the crime lab has concluded that the finger print that was recovered belonged to the boyfriend‚ they were from a piece of notebook paper found under the body of the victim. Interviews are conducted in criminal cases for the purpose of gathering information from people who have‚ or may have‚ knowledge needed in the investigation. (Swanson
