The Effects of Individuals’ Detection of Changes in Images on Reaction Time Abstract The purpose of this current study was to examine how individuals detected or noticed change when viewing images on their level of attentiveness. The experiment consisted of 22 participants who had to detect change across conditions for 20 minutes. These conditions were importance of change (marginal and central) and change type (color‚ location and disappearance and reappearance of images). These

If the solution appears milky than it is known as a precipitate reaction‚ meaning it is soluble‚ and that the ions separated and became surrounded by water. Precipitates in this experiment are electrically uncharged. To identify which compounds are

BIOLOGY LAB REPORT (UNIT 7: ENZYMES) GENERAL Enzymes are protein that acts as catalyst‚ lowering the activation energy need for reactions to progress in cells. The reaction can still occur without the presence of the enzyme‚ but at a much slower rate. The activation energy is the minimum amount of energy need for a chemical reaction to occur‚ yielding from a given set of reactants. In enzymatic reactions‚ we have substrates which are reactants of reaction bound to an enzyme. While an active site

Organic Chemistry II Lab Diels Alder Reaction Purpose: In this experiment a Diels-Alder reaction was used to form the products. Cyclopentadiene and maleic anhydride were reacted together to form cis-Norbornene-5‚6-endo-dicarboxylic anhydride. 7-oxabicyclo{2.2.1}hept-5-ene-2‚3-dicarboxylic anhydride was also produced through a Diels-Alder reaction with the combination of furan and maleic anhydride. Equation: Procedure: Part 1 In a flask equipped with

INTRODUCTION The lab introduced the relationship between reactants and products‚ and sought to discover which ratio of an acid and base reaction produced the most amount of carbon dioxide gas (CO2) without leaving leftover reactants. 5 varying amounts of bases were added to a constant amount of acid (10 ml) to better understand which ratio was the most efficient. RESULTS Data collected from the lab suggests that the ratio of acid to base that produced the most carbon dioxide gas (CO2) was 1:0.5

Enzymes Lab Report Inroduction In this lab we explore an enzymes activity and how it can be affected by changes to its environment. An enzyme is a protein and is a catalyst to chemical reactions. It helps accelerate reactions by lowering the activation energy‚ which is needed for reactions in cells to progress at a higher rate. Activation energy is the minimum amount of energy needed for a chemical reaction to occur‚ yielding products from a given set of reactants. (Unit 7: Enzymes lab) Products

Reverse Transcription Polymerase Chain Reaction (RT)-PCR Employing PCR-based procedure in analyzing RNA would require cDNA to be synthesized using reverse transcription. When reverse transcription and polymerase chain reaction are combined together‚ it will permit detection of low abundance RNAs. RT-PCR is distinct from Real Time Polymerase Chain Reaction (qPCR). The latter measures the amplification of DNA in quantitative way and it uses fluorescent
