In this report‚ the concentration of total protein and albumin were calculated with the interpretation of a standard curve. To determine the concentration of total protein in human serum‚ a total protein assay was performed by using the Biuret reagent. Proteins react to this compound because it contains two amide bonds. When the Biuret reagents is introduced to a sample of protein‚ it forms a blue or violet complex. The concentration of albumin in human serum is determined by using the Bromocresol

What Factors Affect the Rate of Photosynthesis in living leaves? Abstract: In this lab‚ four different types of leaves were tested to see the rate at which each leaf photosynthesized. This lab demonstrates how plants store light‚ capture light‚ and use light as energy for reproduction and growth‚ by photosynthesis. The control in this experiment was spinach‚ which was tested before any of the other plants were. The other plants that were tested were English Ivy‚ C4 Plant‚ and a multicolored

Biology Enzyme Catalase Investigation Aim: The aim of this investigation is to study and observe whether or not the concentration of hydrogen peroxide (varying from 10 – 30 millilitres) affects the rate of reaction. Hypothesis: With the increase of the concentration of Hydrogen Peroxide 3% substrate‚ I prediction that the rate of pressure increase will begin to amplify. The pressure is bound to increase because the catalase quickly reacts with the hydrogen peroxide; this is why the more substrate

My hypothesis was ‘as the surface-area-to-volume ratio decreases the diffusion rate increases’ my results support my hypothesis‚ because in my table of results when the surface area to volume ratio is at 14 the diffusion time is 38 seconds‚ then the ratio goes down to 9‚ and the time increases to 90 seconds. My graph also supports

How weather can affect food prices Diagram 1 - supply and demand: P = Price Q = Quantity D = Demand S = Supply Q₁‚ P₁ = Original equilibrium Q₂‚ P₂ = New equilibrium Diagram The main factor that I will focus on in this price shift is the weather. That is because the weather is one of the most important factors when it comes to agriculture. As you can see in the diagram above; when the supply decreases there

CHM 116 Lab Investigations of Buffers I. Purpose The purpose of this experiment was to get an understanding as to how to properly prepare chemical buffers. Also part of this experiment was to gauge the effectiveness of the buffers by measuring their pH levels in various titration solutions‚ using a pH meter. II. Procedure To start our experiment we had to prepare Buffer B‚ which was the .060 M Ammonia/Ammonium solution. Using 3.0 M ammonia‚ we had to calculate

which listening to music can affect the body and brain. Specific Purpose: To inform the audience as to how music can affect the moods of an individual‚ the brain function‚ productivity‚ and stress and anxiety. Thesis: Listening to music is a very popular and common activity among many people of all ages‚ and while most people listen mindlessly without thinking about the effects it has on our body‚ music plays a huge role in how our brain functions‚ our moods and health‚ and how we go about life.

1.0 Introduction of Investigation Investigation can be defined quite simply as a systematic fact finding and reporting process. It is derived from the Latin word vestigere‚ to “track or trace‚” and encompasses a patient‚ step-by step inquiry. Investigation is finding facts; it is akin to research conducted in the academic arena. Investigation is a multi-disciplined field of study. It encompasses law‚ the sciences‚ communications‚ and a host of other things. Investigation requires an inquisitive

The Sociological Investigation ~ These notes are taken and adapted from Macionis‚ John J. (2012). Sociology (14th Edition). Boston: Pearson Education Inc. There are two basic requirements for sociological investigation: 1. Know how to apply the sociological perspective or paradigms or what C. Wright Mills termed as the “sociological imagination.” 2. Be curious and ready to ask questions about the world around you. There are three ways to do Sociology. These three ways are considered as

Solutions and Their Concentrations 1. Molar Concentration or Molarity – Number of moles of solute in one Liter of solution or millimoles solute per milliliter of solution. 2. Analytical Molarity – Total number of moles of a solute‚ regardless of chemical state‚ in one liter of solution. It specifies a recipe for solution preparation. 3. Equilibrium Molarity – (Species Molarity) – The molar concentration of a particular species in a solution at equilibrium. 4. Percent Concentration a. weight
