purpose of antimicrobial drugs is either to inhibit virus replication‚ without harming host tissues or to interrupt the cell processes or structures of bacteria‚ fungi‚ and protozoa. This lab has brought great interest to me because this is the way physicians’ control/treat infectious disease within our bodies. In this lab‚ chemotherapeutic agents were evaluated by the disk-diffusion method. Chemotherapeutic agents are placed on the surface of a Petri plate containing Mueller-Hinton agar‚ which allows

December 5‚ 2012 Lab Section 503 Abstract The over all goal of the Irresistible lab was to verify a buffer’s ability to resist changes in pH with consecutive 1mL additions of either a strong acid (HCl) or base (NaOH). The experiment entailed preparing a combination 10 buffered and non-buffered solutions and then monitoring the pH changes as a strong acid or base was added to the solution. By performing this experiment‚ it was found that with increasing amounts of buffer in the prepared solutions there

colorless when suspended in an aqueous medium. To study their properties and divide microorganisms into specific groups for diagnostic purposes‚ biological stains and staining procedures‚ in conjunction with light microscopy‚ have become major tools in microbiology. Chemically‚ a stain may be defined as an organic compound containing a benzene ring plus a chromophore and an auxochrome. Stains are of 2 types: 1. Acidic stains e.g.‚ picric acid 2. Basic stains e.g.‚ methylene blue. Types of staining techniques:

How does the concept of civic culture’ differ from that of political culture’? To what extent can the latter explain why the politics of countries differ? "When we speak of the political culture‚ we refer to the political system as internalized in cognitions‚ feelings‚ and evaluations of its population." Almond and Verba In their classic 1963 study‚ Civic Culture‚ political culture was defined within very narrow parameters‚ concerning only political’ attitudes. This neglected the existence

transport of water molecules across a selectively permeable membrane” (Lab Manual 2nd edition). It was hypothesized that osmosis will occur when there is an uneven distribution of solute in a solvent. The more abundant the solute is in solvent‚ the higher the rate of osmosis through the diffusion gradient forming a hypertonic or hypotonic solution. Solvent with equal or no solute forms an isotonic solution. Throughout this lab‚ data was collected and compiled to analyze these effects across selectively

Unknown Lab Report Microbiology Unknown A Sonia Kabra November 26‚ 2014 Introduction There are numerous reasons for identifying unknown bacteria. Some of these organisms have distinct qualities that set them apart from one another‚ such as the exposure to certain environments. Through out the semester in the laboratory‚ we are able to encounter some of the few microorganisms that we as humans have come into contact with. With the knowledge gained from the sessions in the laboratory‚ we can now

1. Describe the two theories regarding how inmate culture becomes a part of prison life. a. Culture is indigenous to prisons; it was believed that it was developed as inmates’ loss connection to their previous environment and freedom. b. Culture is imported‚ in other words inmates brought in some types of characteristics into the prison that would then help create a subculture. 2. List the methods correctional agencies use to control prison gangs. a. Transferring gang members to maximum-security
