the building blocks of muscle in a cell. Nucleic acids are used to transfer genetic information from one cell to the other. The purpose of this lab is to simply determine the absence or presence of the main chemical content of a given substance. In previous labs‚ there were tests with three chemicals‚ Lugol’s solution‚ Benedict’s solution‚ and Biuret solution. The tests were qualitative and tested for the presence of sugars‚ starches‚ or proteins within a given substance. The substances were already

is no such thing as animal testing. One day your kid gets sick‚ deadly sick with smallpox‚ you take them to the hospital‚ they inject your kid with a bunch of random medicines to try and help but nothing helps. Your child later dies because there was no way to help‚ all of those doctor bills‚ useless injections‚ and the death of your child could have been avoided if there was animal testing to find the cure. Animal testing is needed in our world‚ we need animal testing to find cures for deadly diseases

There are several purposes to the amino acid lab experiment. One reason is to help us understand the concept of acids and bases and how they interact with one another. Another purpose is to understand what occurs when placed with the existence of buffers. Lastly‚ the experiment is to help us understand the applications of titrations and how it can be used in a real world setting‚ in this case‚ the identification of an amino acid. One must understand that amino acids all have special characteristics

Alhia Harris October 18‚ 2011 Biology Lab report Proteins are very important throughout the body. They have a lot of functions in cells. Antibodies are proteins that help cells rebuild the cells when they are destroyed. Transport proteins move substances from one place to another. Regulatory proteins control cellular metabolism in a way that cells throughout the body can have the right amount of glucose in the blood. A common protein is an enzyme; in cells they speed up chemical reactions. For

Moment of Inertia and Rotational Motion Garret Hebert PHY 2311 Tues 1:00 garret.hebert@hindscc.edu Abstract: During this lab we will study what rotational Inertia is and how different shapes of masses and different masses behave inertially when compared to each other. We will specifically study the differences of inertia between a disk and a ring. We will use increasing forces to induce angular acceleration of both a disk and a ring of a certain mass. We will then then measure the differences

characterization of a material’s properties. Among those properties the greatest interest lies in the strength of materials‚ being the most basic requirement for any kind of construction. This lab aims first to describe the strength of 1045 annealed and cold-rolled steel‚ 2024-T4 aluminum‚ and cast iron through tensile testing. This includes characterization of yield strengths‚ modulus of elasticity‚ ultimate tensile strength‚ and fracture strength for each material. An emphasis is placed on elastic-plastic

6.1 Testing Principle Following are the testing principles‚ which are used: The role of a test plan is to guide all testing activities. It defines what is to be tested and what is to be overlooked‚ how the testing is to be performed (described on a general level) and by whom. It is therefore a managerial document‚ not technical one - in essence; it is a project plan for testing. Therefore‚ the target audience of the plan should be a manager with a decent grasp of the technical issues involved. You

Ellen Grant Honors Bio I Organic Compounds Problems and Objectives: The purpose of this lab was to select the suitable test for an organic molecule and define the safe process for that test. An organic molecule is normally found in or produced by living systems. (Unknown Author‚ 2014‚ www.biology-online.org/organic_molecule)In this lab one was supposed to infer the results of the test and be able to identify if major biomolecules are present. You were to analyze a variety of tests including

Introduction Chemical kinetics is the study of reaction rates. A reaction rate is the speed of the change in either reactants or products over a period of time. General kinetic rate equation is: Where [A] and [B] are the concentration of the species in the reaction. The variable k is the rate constant‚ which is a function of time and catalyst presence. The variables m and n are the order of reaction for their respective species concentration. The higher the value of the reaction order the
