the unknown experiment is to understand and identify a gram positive and a gram negative. Bacteria can be very helpful in clinical uses and many pharmaceutical drugs are based on the organism. Knowing how a bacterium works and how it is structured can be crucial to determine how it affects each individual. Several biochemical tests were performing to separate and determine the identities of the microorganisms. Broth tube number 31 containing unknown microorganisms. One of the microorganisms is gram positive which can be separate from the gram negative using the four-way streak isolation from the lab manual. The purpose of the streak isolation is to obtain single colonies on a Columbia CNA agar plate. C-CNA agar is a type of selective media that can be used to select for gram positive (Cain et al., 2014). Gram stain was performing in order to confirm the isolation of gram positive which had the end result of purple stained cocci. Catalase test was negative because there was no bubble observed which concluded the genus of the gram positive is Streptococcus. Streptococcus ID introduced many different tests to further identify the gram positive species. One-fourth of the blood agar plate is to determine the hemolysis of the bacteria which is Alpha/Beta because of the partial to complete clearing of the red blood cells. Three-fourth of the plate was used in order to see the susceptibilities of the SXT and Bacitracin discs. There was no zone clearing for SXT which is resistant…
specific organism. Methods and Procedures Our group was given unknown bacterial sample number 7 to test and identify. As with all other experiments where we dealt with bacteria, aseptic techniques are necessary to prevent contaminated test samples and incorrect data. Our first procedure was to streak two agar plates to observe growth factors. A sterilized inoculating loop was used to streak first a mannitol salt agar (MSA) plate. This media is selective and inhibits the growth of Gram negative…

Since the dawn of time, technology has been significantly life changing. As modern day humans discover mind blowing uses for the technology, it is shared and used among society, until something else is improved or created. Modern day technology, such as cell phones, computers, and television, allow for a whole new approach to communication, and create platforms to share beliefs, ideas, and news. It has allowed for families and friends to communicate easily and bond even when they are miles away…
uses technology to give people their food ASAP, so they do not have to wait. Fast food, with the help of technology, has made it possible for people to grab food to go at any point and time, without having to wait a few minutes. It has affected the ability for parents to be able to effectively teach and communicate with their children. Technology captivates the hearts and minds of youth; completely captivating their attention and distracting them from the important moments of life. And…
Gerard Jones is an American author and a comic book writer about media. Jones argued in his essay “Violent Media Is Good for Kids” to discuss several good reasons that violent media is beneficial to kids.

Jones believes violent media assistances children to be more courageous to face their obstacles. Jones gave a very good example of his son, who was not able to…
Modern media is made by a small number of people and usually relies on technology. Storage and transmission with media began more than 30,000 years ago such as cave drawings. Modern media must go out a mass amount of people which means mass production. Gutenberg Press which is the first printed press and it printed 180 copies in Europe. Which started newspaper in the 1960s in England. The idea of photographs is more than 1000 years old. Radio was invented in 1894 and became a wireless…
