Groundwater is an important source of drinking water for more than half of the nation’s population and nearly all its rural population. In recent years‚ widespread reports of bacteria‚ nitrate‚ synthetic organic chemicals and other pollutants in groundwater have increased public concern about the quality of groundwater. What do we know - and what don’t we know - about groundwater quality? What causes groundwater contamination‚ and to what extent are the nation’s groundwater supplies at risk?

Effects of Different Antibiotics on Bacteria Because of their small size‚ rapid rate of reproduction‚ and relatively simple structure‚ bacteria are excellent subjects for laboratory studies. This investigation will introduce you to techniques of microbiology that will be of use to you throughout your biological work. Procedure 1. Heat the test tubes of sterile agar medium in the water bath until the agar melts. 2. Remove the test tubes from the water bath. Let them cool enough to hold in your

to avoid is cross-contamination. This essay will tell you what cross-contamination is‚ how it occurs‚ what happens when you eat contaminated food and how to prevent it. To begin with‚ what is cross-contamination? Well‚ cross-contamination is when bacteria from one food is transferred to another and contaminates the other food. Usually‚ contamination occurs between a raw food and a cooked food‚ vegetables and meats‚ or for hygienic reasons. For example‚ cross-contamination can occur if the

The disease I’ve chosen to write my research paper on is Bacterial Vaginosis. Bacterial Vaginosis is vaginal condition that can produce vaginal discharge and results from an overgrowth of normal bacteria in the vagina. In the past‚ the condition was called Gardnerella vaginitis‚ after the bacteria that was believed to have caused the condition. However‚ the newer name‚ Bacterial Vaginosis‚ reflects the fact that there are a number of species of bacteria that naturally live in the vaginal area and

Activity 3: “Using Sources” Emma Ballew Washington State University Tri-Cities For my lesson‚ I did “Using Sources”. 1) The first thing I learned was the 2 different ways to use sources to argue. The first way to use a source is by agreeing with the source (Atias‚ Lennard‚ & Zuckerman‚ 2013). This can be done in two ways. One way is to use the research that other sources have done (Atias‚ Lennard‚ & Zuckerman‚ 2013). Using the research of others can help to lay a foundation for a paper’s argument

The discovery of antibiotics has proved to be a boon a boon to human welfare but some also have the opinion that they are the necessary evils. We do have Alexander Flemming to thank for this discovery back in 1928[1]‚ when he forgot to clean up his workstation before going on holiday after which the golden age of antibiotics started. Antibiotics are the

If bacterial meningitis is suspected several tests sound be done before beginning treatment. A blood sample should be taken and a complete blood count (CBC) should be performed and a lumbar puncture should also be performed as soon as possible. Laboratory findings The white blood cell count (WBC) should be 5‚000-10‚000 /mm3. Critical values associated WBC are 30‚000 /mm3. Variables that may increase white blood cell count include: Physical activity and stress‚ final months of pregnancy and/or labor

This type of cross-contamination is especially dangerous if raw foods come into contact with cooked foods. Here are some examples of food-to-food cross-contamination: * In a refrigerator‚ meat drippings from raw meat stored on a top shelf might drip onto cooked vegetables placed on lower shelf. * Raw chicken placed on a grill touching a steak that is being cooked. Top of Page People to Food People can also be a source of cross-contamination to foods. Some examples

multiple cloning site (MCS) which is artificially implanted by adding a polylinker sequence to it. The pUC19 plasmid is also altered by inserting a gene that codes for beta-lactamase which confers resistance to the antibiotic ampicillin (Read and Strachan 2011). The MCS occupies the 5’ end of the gene lacZ (Sherwood‚ Willey and Woolverton 2012). This gene codes for only the alpha-peptide of beta-galactosidase‚ an enzyme used to break down the disaccharide lactose into glucose and galactose (Read and
