Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

Sofia Dominguez 10-O 19/03/14 Effect of pH on germination of seeds: Design Practical Introduction: The term pH stands for Hydrogen Potential it is used to determine the acidity of a substance. The pH scale goes from 0 to 14. The values that are smaller than 7 indicate the range of acidity. Higher pH values are alkaline and a pH of 7 is neutral. Acidity is a function of the concentration of hydrogen ions (H+)‚ or protons. The strength of alkaline solutions is measured by the concentration of hydroxide

Photosynthesis Lab Report Purpose: To research the effect of different wavelengths (colors) of light on plant growth during photosynthesis. Background Information: Photosynthesis is the process by which sunlight is captured by chloroplasts within plant cells and turned into energy. This energy is used to help the plant grow roots‚ leaves‚ flowers and fruit. Energy is required by living things

connectors. THEORY: The oscilloscope is a very widely used instrument because of its versatility. It is a standard piece of equipment used in many types of scientific laboratories. It moves a beam of electrons across a fluorescent screen that gives off light where the electrons hit it. It can be used as a graph to draw vertical and horizontal displacement from the origin along the y and x axis respectively. The values displayed along these axes are that of the voltage. The y measure is taken to be the

Title: You Light Up My Life Purpose: To determine how different environmental conditions affect a plants starch levels. Hypotheses: 1. If the plant that is in absence of CO2 and is kept in a closed environment‚ then it will have a starch level of 1 because the plant is missing CO2‚ which it needs to complete the photosynthesis process. 2. If the plant is in a closed environment‚ then the plant will have a starch level of 3 because it has all the environmental conditions it needs. 3. If the plant

Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

EXPERIMENT NO. 1 INTRODUCTION TO LAB INSTRUMENTS. 1. BREADBOARD We should be familiar to the following things about a breadboard: * What is a breadboard and what is it used for? * How does it work? * Setting Up. * Limitations. What is a breadboard and what is it used for? A breadboard (or protoboard) is usually a construction base for prototyping of electronics. The term "breadboard" is commonly used to refer to a solderless breadboard (plugboard). It was designed by

TITLE OF EXPERIMENT 2 : DILUTION 2.1: OBJECTIVES Upon completion of this experiment‚ students should be able to: 1. determine the concentration of coloured solution such as FeCl3 by using dilution and colour differentiating (colorimetric) techniques. 2.2: INTRODUCTION Concentration can be expressed in many different ways such as percentage volume and percentage weight etc. In laboratory‚ normally concentrations were expressed as molarity and normality. Molarity is the
