Adwoa Fosuah Bio Psych Lab Report 4 Cold Pressor Task Aim The cold pressor test is done by having the subject submerge their hands in a bucket of cold water to determine cardiovascular changes such as blood pressure and heart rate. For this experiment we wanted to know how long participant can keep their feet in the bucket of ice water before they experience any pain while looking at neutral and positive pictures and also rate the intensity of their pain. For this reason we hypothesized that

Diffusion Lab Report Emily Cocq Research Question: Will there be a difference in the experimented potato cores after being subjected to high concentrations of sugar? Introduction: Water can move through protein channels in cell membrane/cell walls. The water will move due to the water potential of the cells. If there is a greater concentration of solutes (chemicals) inside the cell than outside the cell and the chemicals can not move‚ then water will respond by moving into the cell. This process

affect the cell membrane‚ thus would then releases the purple pigments out of the vacuole which causes the leakage of the purplish liquid. Background Information The outermost layer is the cell wall‚ which is present only in plant cells and is made up of a carbohydrate called cellulose and also has other protein substances embedded within it. The cell wall is a rigid layer and gives structural stability to the cell and also limits the permeability of large substances into and out of the cell. Within

Lab report As part of my module Nip1002 I was required to perform a set of observational skills which included; pulse‚ blood pressure‚ respirations‚ hand washing and urinalysis and then compare them to previous results. In this lab report I am going to discuss blood pressure in detail. Procedure * Explain the procedure to the patient and gain consent * Wash hands thoroughly following the hand wash technique to prevent the transfer of bacteria * Clean equipment e.g. blood pressure cuff

Chemistry Lab Report Water Hydration Introduction: A hydrated crystal or hydrated occurs when water becomes tightly attracted to a metal salt base on it’s polarity. The water molecules maintain integrity as molecules‚ however they are considered to be part of the formula of the hydrate. When the hydrate metal salt crystal is heated‚ the attractions to the water are broken by the heat energy and the water escape from the crystal. After heating the salt crystal is called as anhydrous‚ which

Introduction Regulating the water in living organisms is very important. Throughout the body‚ water transports nutrients and removes excretory products. The human’s total body weight is about sixty to seventy percent water (age‚ gender and weight can be a factor in this statistic along with many others). Furthermore‚ water is very crucial to living organisms‚ because it maintains the body temperature and metabolizes body fat. If your body doesn’t receive enough water‚ it will take water from other

Coulomb’s Law Purpose: The purpose of this lab was to demonstrate that the force between two stationary charges is directly proportional to the product of the charges and inversely to the square of the distance between them. Coulomb’s law tells us that the force between two charges depends (1) linearly on the strength of each charge‚ and (2) inversely on the square of the distance between them. Mathematically we would write this as . Procedures Part1 Begin by removing the right side

Lab Report 1: Subculturing Adherent Cells Fibronectin‚ integrin alpha 3‚ and actin are all involved in cellular adhesion at both the cellular and molecular levels. Integrins are the primary trans-membrane receptors that mediate dynamic interactions between the extracellular matrix and the actin cytoskeleton whenever a cell is motile. Integrins bind to the extracellular matrix and link to the actin cytoskeleton via a shirt cytoplasmic tail; they also help determine cellular binding specificity because

INTRODUCTION The measurement of fluid flow is very important in our daily life from measurements of blood-flow rates in human artery to the measurement of liquid oxygen in a rocket. In this experiment‚ students are to adapt to various ways to measure the flow of essentially incompressible fluids by using the flow measuring apparatus. Students will also be able to understand the application of Bernoulli’s equation in this experiment. The flow is measured by using a venture meter‚ an orifice meter
