Practical 1 - Investigation into size and scale of microscopic tissues This practical focuses on microscope technique and using graticules and stage micrometers to determine size and scale in biological cells and tissues. Intended learning outcomes By the end of this practical you should be able to: • Use a microscope fitted with an eyepiece graticule and stage micrometer • Calibrate the eyepiece graticule using the stage micrometer • Use the calibrated graticule to determine the actual

Acids and Bases are two groups of chemical compounds that generally have opposite characteristics. They have there own unique traits‚ acids taste sour‚ turn litmus red while bases taste bitter and turn litmus blue. The term pH relates to measuring the acidity or alkalinity of a solution‚ such as vinegar‚ or even a damp substance like soul. The neutral pH is 7‚ which is essentially water‚ with lower numbers indicating acidity and higher numbers indicating alkalinity. Hydronium ions (H3O+) are

The Vineland Adaptive Behavior Scale-II (VASB-II) was completed by Leyla’s mother to determine Leyla’s daily functioning skills. More specifically‚ these daily skills are necessary to get along with others and taking care of oneself. The VASB-II included domains in communication‚ daily living‚ and socialization. Leyla’s mother spoke with the evaluator about Leyla’s functioning skills at home‚ at school‚ and in the community. Leyla achieved a standard score of 113‚ which is in the Adequate adaptive

Purpose: The purpose of this lab was to test how objects slightly acidic or slightly basic will affect the way catalase‚ the enzyme tested‚ denatures‚ or breaks down. Hypothesis: If the potato is acidic‚ it will react with the H2O2 more than it will with the raw‚ plain potato because the acid will denature the enzyme faster. The manipulated/independent variable is the raw‚ plain potato while the responding/dependent variable is the other types of potatoes used in the experiment. Materials:

SMALL-SCALE MINING (Lives at risk in the Philippine Gold Mines) INTRODUCTION Gold is the number one mineral produced by the Philippines in value terms. Although total local production was low relative to world production‚ it ranked 2nd to Africa in gold production per unit land area in 1988 and ranked 29th as top gold producer in 2002(Israel and Asirot 2002). In the year 2002–2007‚ the Philippines’ gold production increased by 8.2%. This contributed an average of 2% gross domestic product (GDP)
