Overview A transistor is a semiconductor device that amplifies and switches electrical currents. They are the core component of any modern electronic devices‚ such as computer‚ telephones and other electronics. Nowadays most transistors are use to produce integrated circuits. There were a numerous inventions‚ or problems with the inventions that lead to the birth of the transistor. Radio signals‚ could be sent carrying information over a long distance away; the only problem was there was no device

things can look and feel clean but they are actually filthy. It is also crazy how many surfaces we touch every day and how one thing we touch can make us sick. Overall‚ I learned many things about growing bacteria. Hypothesis I think the computer lab keyboard will have the most germs. I think that because it is the hardest to clean and many kids touch it.

Microbiology Lab Report II Title: Determination of a Bacteriophage Titer Purpose: To determine the number of phage particles or plaque-forming units in a suspension of T4 bacteriophage. Materials: 18 24 hour broth culture of Escherichia coli B. 2 ml suspension of T4 bacteriophages with a titer of at least 10‚000 phages/ml 5 trypticase soy agar (TSA) plates. These should be warmed to 37c before use 5 tubes of soft agar (0.7% agar). Prior to

disk‚ impregnated with the compound to be tested‚ is placed on the surface of the agar. The compound diffuses out from the filter paper into the agar. The concentration of the compound will be higher next to the disk‚ and will decrease gradually as distance from the disk increases. If the compound is effective against bacteria at a certain concentration‚ no colonies will grow wherever the concentration in the agar is greater than or equal to that effective concentration. This region is called the

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 a gram negative bacterium that will grow rapidly given ‘any culture medium with the necessary energy source‚ nutrients‚ pH‚ and temperature’. Therefore‚ MacConkey Agar being the

Experiment 6: Microbial Cultivation Objectives: To successfully cultivate microorganisms from different sources to medium. Materials: Broth‚ Agar‚ Sterilized cotton swab‚ Procedure: 1) Get your broth with cotton swab inside containing your bacteria. 2) Remove the cotton and flame sterilize the mouth of the testtube. 3) Get your cotton swab inside‚ flame sterilize again the mouth of the testtube then plug it with cotton. 4) Grab the inverted plated media and flame sterilize the
