hope to fully understand the Stroop effect‚ yet several issues remain open. The primary purpose of this study was to determine whether the Stroop phenomenon is equally strong in both brain hemispheres. Participants collected from our research methods lab were asked to complete an online experiment measuring the time of interference it took them to depict the color of the ink of the color-words. Furthermore‚ each color was assigned a number. For example‚ the ink color red was represented by the number

Carbohydrate Lab Report Introduction Qualitative identification of a substance is of significant importance in chemistry. Physical constants such as melting points have traditionally been used by organic chemistry for identification of unknown compounds. As for inorganic substances‚ the precipitation of a solid‚ results of a flame test‚ or the formation of a colored substance could all be keys to identifying a sample. Chromatography and spectra are amongst the newer techniques

Table 8.1- Combustion of magnesium ribbon Observations Reaction was exothermic; magnesium ribbon burned and was glowing a bright white color when ignited. Reactants: Mg and O2 Products: MgO Balanced chemical equation 2Mg + O2 2MgO Table 8.2- Combustion of heptane Observations When holding test tube inverted over heptane flame‚ condensation formed against top walls of the test tube. When the burning splint was added the walls of the test tube became less foggy from the condensation

The Gene Lab 1. Introduction The purpose of this report is to inform dog breeders of a very common genetic disease known as Progressive retinal atrophy (PRA). The report will also inform buyers of the disease so they are aware of the disorder and they can check to dog’s pedigree for the disease. PRA could affect any dog‚ as a result of this it is recommended that the offspring should be examined by a board-certified veterinary ophthalmologist and screened for the existence of the disorder.

Ketchup Lab Report Problem: People visiting fast food restaurants complained that ketchup was dripping onto their fingers and clothes. What could we do to insure that the ketchup will not drop all over the customers? Hypothesis: If I put one ketchup packet in a hotter bath then it will move faster down the styrofoam plate. Independent Variable: The temperature Dependent Variable: The viscosity of the ketchup’s “runniness” Constants: The type of ketchup

Introduction Reactive oxygen species (ROS) include super oxide ion (O2-)‚ hydrogen peroxide (H2O2) and hydroxyl radical (HO- ) are the causative agents to produce oxidative stress. ROS are produced by two independent pathways: mainly the mitochondrial oxidative metabolism and cellular responses to bacterial invasion‚ xenobiotic and cytokines. To counteract the formation of ROS‚ a number of antioxidant proteins have been described. These proteins are superoxide dismutase‚ catalase‚ glutathione peroxidase

Stoichiometry lab 1 Purpose: The purpose of this lab is to find the limiting reactant‚ also to find the percentage yield and percentage purity of the reaction that happens between Calcium Chloride and Sodium Carbonate. The other purpose was to know how the reaction can be balanced and created. Hypothesis: In this lab we are going to see a precipitation reaction. This is a reaction where two soluble salts Sodium Carbonate and Calcium Chloride are added together and the result is the precipitation
