...Vass, Ed.D. Version 42-0007-02-01 Lab RepoRt assistant This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor. Exercise 1: Observing Blood Questions A. What are the components of blood? Plasma, platelets, red blood cells and white blood cells are the components of blood. B. What is the function of red blood cells? Red blood cells carry oxygen to your cells and remove carbon dioxide from your cells. A. C. List the five types of leukocytes and describe the function of each. Neurtophils are white blood cells that attack the infection before other white blood cells. Eosinophils are white blood cells that protect the body by killing and swallowing bacteria. Monocytes help with immune defense and rebuild damaged tissue. Basophils increase in numbers when the body has an infection and accumulate at the site of the infection. They help to increase blood flow and decrease inflammation. Lymphocytes are mostly responsible for helping the body’s immune system. They consist of B and T cells. B cells release antibodies into the body’s fluids and T cells directly attack viruses. www.LabPaq.co m 14 ©Hands-On Labs, Inc. Experiment CardiovasCular...

...environemnt while operating around it. Kineses is a random movement in response to an environmental incentive. When animals behave in a kinetic way, they are not moving towards or away from the stimulus, just in correspondence to it. It is important to consider that this was only one trial. It is practical to accept the hypothesis because the pill bugs could have used cell communication to split up to obtain an equal amount of the varying substances. In addition decomposing organisms need four key elements to thrive, nitrogen, carbon, moisture, and oxygen. The organisms may have sensed these substances in both the lemon juice and the bleach, so no preference was established. The usage of second messangers could explain this because they are molecules that relay signals obtained at receptors on the cell surface in order propose the arrival of vital substances. Sources of error include that I did not perform enough trials to aquire a definite answer. If I perfomed more trials I would get a wider source of data and be able to determine other factors that are involved in this experiment. Also if others conducted this lab I could have obtained class data for comparing. I also may not have equally allocated the solutions of bleach and lemon juice, and that undermined accurate results. This could be fixed by using a graduated cylinder or a measuring tool that is...

...Life 120 Lab #1 “Cell Structure and Function And Movement of Materials across Cell Membranes” 1-20-15 Plant Cell Structure Abstract: In cells, water will move from areas of high concentration to areas of low concentration. This was addressed by observing the changes in cells as they were surrounded by NaCl solution and later by a water solution. The results support our hypothesis and show that the composition of the surroundings has a visible (under a microscope) effect on the shape and structure of each individual cell. As the NaCl concentration increased, water rushed out of the cells and caused them to pull away from the wall while as the water concentration increased water rushed into the cells and caused them to swell. Introduction: The “big problem” that is being addressed is the change in a cell’s structure when surrounded by different concentrations of solutions. It is known that substances move from areas of high concentration to areas of low concentration, but to validate this knowledge, we must observe the change in a cell from its “normal” state with the addition of solutions. Questions that must be answered are what affect a different NaCl solution has on plant cells as compared to water? The hypothesis being tested in this report is that when a plant cell is introduced to a NaCl solution, the water in the cells will move out to an area of low concentration, thereby altering the shape of the cell. This directly relates to the key question. Materials...

...The Effect of Calcium on Hatching Brine Shrimp Eggs science fair project will investigate how the addition of various amounts of calcium to brine shrimp eggs will affect their hatch rates. I was drawn to this area because I have an interest in how several outside factors can affect the nature of a process. My hypothesis for this lab is that the larger amount of calcium added into a petri dish will result with a faster hatching rate due to the extra nutrients. The independent variable of this lab is the concentrations of calcium, while the dependent variable is the brine shrimp eggs hatch rate. The constant is petri dish A that will have no calcium added. I plan on measuring this rate through observing the individual petri dishes every twelve hours under a magnifying glass and counting the number of eggs that hatch. The science of this lab can be traced back to the background...

...Reports Lean Laboratories: Competing with Methods From Toyota Mark Graban, BSIE, MSME, MBA, CPIM, Shana Padgett, BS, MT(ASCP) (ValuMetrix Services, Ortho Clinical Diagnostics, Raritan, NJ) DOI: 10.1309/LMX0LEMR7R0USKUM Hospital laboratories throughout North America are successfully using “Lean” methods based on the Toyota Production System to win against multiple competitive threats. Some hospitals have used Lean to help eliminate point-of-care testing for the emergency department (ED). Other hospitals have used Lean to “insource” testing that had previously been done in outside reference laboratories. Lean can defend and protect employment for the laboratory, while also improving turnaround times and service for patients and reducing costs for the hospital. Hospital laboratories have also used freed up capacity to increase their reference laboratory work, bringing additional revenue to the hospital. an improvement of 37%, as shown in Figure 1. The laboratory was also better satisfying physicians who ordered tests for morning rounds, as the percent of tests on the charts by 7 am improved from 65% to more than 90%, as shown in Figure 2. After laboratory professionals demonstrated that they could dramatically reduce turnaround times, the ED discontinued the point-of-care trials. Since Lean implementation, Dr. Decker said, turnaround times “are definitely faster. All the docs agree,” adding, “the lab is no longer the rate-limiting step in the process.” Lean Instead of...

...Lab Research Report SCI 110 January 27, 2014 Strayer University Lab Research Report Research in the physical sciences has often been limited by our abilities of safety observing and studying the phenomenon in question. Even before the thought of microscopes, it would have been impossible to comprehend the composition of the most basic cells. The exact issues are the current issues in the field of physical science today, but it’s particularly true in the world of physics. While new technologies exist to measure phenomenon, it is not always safe to do so in the field that deals with radiation, unstable compounds, particles and atoms. As a result, the technology that we have in the field of physics, but across the board in the physical science field of astronomy, chemistry, physics and earth science. Challenges in Measurements Over the years there have been many adventures that allow for direct measurements within the field of physics, there are still many obstacles and challenges to making direct observations. Physics is the study of energy and matter and the interaction between-both of which are impossible to observe with the naked eye. The first major challenge in making direct measurement in physics is the size of the particles being studied. To solve this issue, physicists study these particles indirectly through things like associated radiation, their energy, or the displacement of other atoms. Almost all measurements that have been made on atoms or...

...UTAR FHSC1214 Fundamentals of Cell Biology Trimester 1 How YOU can do well in BIOLOGY Follow the 4A’s and you can expect A’s. A ttitude • Attend ALL lectures, tutorials and practicals on time without fail. • Be attentive in class and revise your notes after class while the topic is still fresh in your mind. Why waste time re-reading 2-3 months later? • Do your assignments faithfully as they carry marks for the finals. • Come prepared for lessons (i.e. read up beforehand). • Read up beforehand before attending lectures so that you won’t be lost and wasted hours of your life week after week. • Why stress yourself out if you can avoid it? Do NOT count on last minute revision for tests and examinations, as it will be too late to catch up and seek help in areas where you may find confusing or unclear of. • Why panic before exams because you can’t find this or that? Keep separate files for lecture, tutorial and practical. File up the respective notes systematically so that you do not lose them along the semester. • Do you expect the lecturer/ tutor to be available all the time to answer your questions? It is YOUR responsibility to take the initiative to clear your doubts or satisfy your curiosity to understand certain scientific phenomena by reading up on the relevant topics.

...In “Compassionate Cosmetics” (Kathi, Keville) it mentions “As the validity of animal testing falls further into question, interest in alternative testing methods is on the rise. These include cell cultures, eye bank corneas and sophisticated computer and mathematical models. Statisticians and epidemiologists also can judge safety by analyzing clinical surveys, human volunteers, case studies, autopsy reports, statistical analyses and environmental factors related to human disease. As technology advances, these types of tests are becoming less expensive and often produce much faster results than traditional animal testing.” “The United States Department of Transportation, Consumer Product Safety Commission and Food and Drug Administration (FDA), among others, have approved the use of Corrositex, a protein membrane designed to function like skin. It can replace rabbit skin tests with results available in just a few hours at a low cost of $100 per test—compared to the 21-day, $1,000 price tag of a single Draize rabbit test, a traditional method...
