The machine was unplugged. * Using a ruler‚ a pencil and the Ticker Tape‚ all the data were recorded on a Data Table. * Using the Data Table the position versus time graph and the velocity (instantaneous) versus time graph were plotted. Analysis There were in total of 37 dots recorded on the piece of the Ticker Tape. Every sixth dots represented the 1/60th of one second. Because of the lack of the information‚ as shown on the Data Table‚ every third dots were used to expand the amount

Introduction The lung is a spongy organ made up of of irregularly shaped air spaces called Alveoli. The alveoli are lined by a single layer of flat cells and supported by a mesh of fine elastic fibers. The alveoli are surrounded by a rich network of pulmonary capillaries (Couch and Berger‚ 2004). Our lungs are a network of connected tubes that bring oxygen from the air into our blood‚ nourishing the trillions of cells that make up our bodies. The lungs also clean the blood of carbon dioxide waste

ADI Lab Report Every living thing is made up of cells. All cells have some part in common. Some multicellular cells are highly specialized and carry out some very important functions. One of the special cells are red blood cells‚ their functions‚ transporting oxygen from the lungs to the cells in the body. Red blood cells look like little discs. Red blood cells can change their shape‚ this ability allowing them to squeeze through capillaries without breaking. Our task is to Design and carry out an

A. Avril Crayfish Lab Report November 9‚ 2012 Dr. Marvin Results: Figure 1. Firing Rate of Tonic Receptor in Response to Stretch. The correlation between Firing Rate and Stretch of the slow adapting crayfish receptor for four different sets of data is represented in this figure. The recordings are taken at stretches of 2‚ 4‚ 6‚ 8‚ and 10 mm of the crayfish tail. The best fit lines for the different sets of data are as follows: Ali and Emily- Linear best fit line‚ Dave and Laura- Exponential

In 1860‚ the first instrumental analysis was performed by Robert Bunsen and Gustav Kirchoff who used flames tests that led to the discovery of the elements rubidium (Rb) and caesium (Cs). After this‚ this method was used everywhere to find the chemical make ups of many substances. For example‚ in 2007 there was a huge problem where tainted pet food would cause many pets to become ill. Qualitative analysis was used and it was discovered that Melamine was found in the pet food which altered the results

Introduction and Purpose: This lab focuses on how weight affects the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s) respectively. The primary goal of this lab is to investigate and explain the relationship of these two factors. During the process of conducting this experiment‚ learning to design a lab will also be achieved. Research Question: What is the effect of weight on the time it takes for a rotocopter to fall from a drop height of 1 and 2 meter(s)? Variable

Hanging at a Constant Determining the effect mass has on acceleration Block 5 11/25/12 Purpose: The purpose of this lab is to determine the effect of additional mass added to a cart’s existing mass‚ without changing the applied force‚ on the acceleration of the cart. We will test this effect by hanging a constant mass to a cart and use a computer program‚ LoggerPro‚ to calculate the acceleration which is expressed through the

Purpose The purpose of this experiment was to become familiar with the electrocardiograph to help us determine the electrical activity of the heart. As well as‚ to observe how exercise and different body positions(conditions) can affect the activity of the heart. Introduction Trained professionals can look at the EKG tracing and determine if the heart is normal or if the heart is abnormal. “An ECG records the electrical activity of the heart. The heart produces tiny electrical impulses which spread

Malak Zomrawi 4/9/15 Bacterial Transformation I. Abstract In the lab‚ the purpose is to see if we could move genes using plasmid. As well as getting better understand of transformation methods using shock wave. To see the effects five trays are being used containing LB nutrient broth. The results showed that the LB‚ ampicillin‚ and arabinose with a positive pGLO had the most amount of growth compared to the other four trays. Although when there is arabinose there is no fluorescence‚ fluorescence

Instruments: UV/VIS spectroscopy was used to analyze the absorption spectra of the many solutions in this experiment. It was chosen for its ability to collect absorption data quickly and efficiently. A Target Factor Analysis program was used to treat the UV/VIS data collected. Target Factor Analysis was used as the calculation method instead of CLSR due to it taking into account the interference2. Discussion: Table 1 is the calibration matrix
