MANIPULATION OF BACTERIA INTRODUCTION: In this experiment that we performed‚ there were many methods that were used to help us manipulate and identify the bacteria E.coli on a MacConkey agar plate. The first part of the experiment involved the methods of manipulating‚ identifying and counting the bacteria and the second part was to find out whether the bacteria E.coli was the only type found in the given area by gram staining. E.coli was the chosen bacteria for this type of experiment. It is

Lab 3 : Techniques in Microscopy Title : Preparation of light microscope observe cell organisms. Objective : To observe and investigate the cell structure under the light microscope. Introduction A microscope is an instrument used to magnify and resolve a specimen. It is important to know several important features of microscopy which involves magnification‚ resolution and contrast. Magnification is the enlargement of a specimen while resolution is the ability to distinguish detail or the

Acid Base Titration Purpose: The purpose is to calculate the molarity of a NaOH solution by titrating the base with 5mL of standard HCl solution in each trial. By adding the base with unknown molarity to the acid with 0.10M the molarity of NaOH can be calculated. The base‚ NaOH‚ helps bring the pH of the acid‚ HCl‚ closer to seven‚ which neutralizes it. When using the buret the amount of NaOH used is able to be determined. Then by writing a balanced chemical equation and using the titration

Chemotherapeutic Agents of Control: Introduction: Chemotherapeutic agents are chemical substances used to treat various forms of infectious diseases. The chemotherapeutic agent works by stopping the bacteria from reproducing. There are two different kinds of chemotherapeutic agents. The first kind is an antibiotic‚ which slow down the growth of microorganisms. The second kind of chemotherapeutic agent is synthetic drugs. Synthetic drugs are artificially made in a laboratory.

Abstract This lab’s purpose was to test the patterns of percolation in various places. This lab tested how soil would absorb water based on different places. Distance from a group of trees‚ distance from a swamp‚ and different types of soil were tested. From the results collected‚ you can not prove‚ but you can infer that the ability to absorb increases as you go farther away from a swamp‚ and a group of trees. The ability to absorb also increases based on how much silt is in soil. Introduction
