Main aim of experiment 5 is to use the biuret test to quantify the concentration of the Bovine Serum Albumin (BSA) then constructing a standard curve graph and to use the spectrophotometer to perform an enzyme assay using different concentration of the BSA. Experiment 5 also verifies the Beer-Lambert Law‚ which is the linear relationship between absorbance and concentration of an absorbing species. Absorbance formula is shown in fig. 1.1. However‚ the Beer-Lambert Law is not obeyed at high concentration

and so much more. Some factors that affect biodiversity of species are what are around the biomes‚ the unnatural species living there‚ extreme climate changes (in general)‚ pollution‚ unusual weather changes(drought‚ flood‚ snow‚ etc.)‚ littering‚ loss of natural resources‚ extinction of plants/animals‚ and much much more. The difference between biotic and abiotic factors in an animal’s habitat is that the biotic factors are living or have lived while the abiotic factors are not living‚ will not

4 EXTERNAL FACTORS THAT AFFECT HUMAN RESOURCE MANAGEMENT Government Regulations – With the introduction of new workplace compliance standards your human resources department is constantly under pressure to stay within the law. These types of regulations influence every process of the HR department‚ including hiring‚ training‚ compensation‚ termination‚ and much more. Without adhering to such regulations a company can be fined extensively which if it was bad enough could cause the company to shut

Lab Report: How Temperature affects Reaction Rate Aim: The Aim is to investigate how temperature can affect Reaction Rate. The experiment will be performed by heating equally sized and weighted lime stones with equal amounts and concentration of Hydrochloric acid at different temperatures. The temperatures will be 35˚C and 40˚C. We will measure the reaction rates by observing gas release of the reaction between lime stones and Hydrochloric acid. The amount of gas release at different

What factors affect the resistance of a piece of wire? What I am going to investigate is‚ what factors affect the resistance of a piece of wire. To start this experiment I will need the following equipments: Power pack Ammeter Voltmeter 1 meter ruler (100cm) 110cm of wire Crocodile clips This shows how the equipment will be set up. A V I will measure the Voltage and also Current of the wire. Once I have recorded the results

A reaction is a chemical process in which substances decomposes‚ or combines with other substances. In this case it is synthesis chemical process which creates new products. However‚ the rate of a reaction can be altered either faster or slower depending on certain variables. These variables are concentration‚ temperature‚ surface area‚ and catalysts. A reaction can be made faster or slower with a variation in the concentration of reactants; a reaction goes faster when there is an increase in concentration

Concentrations of HCl on the Rate of Reaction Between HCl and Sodium Thiosulfate Chemistry Lab report Aim: The aim of this experiment is to determine how concentrations of HCl acid affect the rate of reaction when reacted with Sodium Thiosulfate (Na2S2O3). This experiment would require measuring the mass of the reaction over a period of time to be able to determine the rate of the reaction. Safety Precautions: In this experiment‚ SO2 gas is produced from the reaction between Sodium Thiosulfate and

of the Enthalpy of an Acid-Base Reaction Abstract The purpose of this lab was to first‚ determine the specific heat capacity of a homemade calorimeter‚ and second‚ to calculate the enthalpy of reaction for an acid-base reaction between 6M KOH and 6M HNO3. To determine the specific heat capacity of the calorimeter‚ two differing temperatures of water were measured and volume was measured and mixed within the calorimeter. The enthalpy of reaction for an acid-base reaction was found by these steps:

SpokAnimal main “priority has [always] been taking in animals from area shelters whenever the need arises” (SpokAnimal‚ 2015b). However‚ a major issue affecting SpokAnimal is the increase in displaced or abandoned animals as a result of recent wildfires. As of 2014‚ SpokAnimal regularly takes in about 3‚301 cats and dogs within a year (SpokAnimal‚ 2015c). This number has only increased since the fires have
