controlled variable is important in order to be able to look at what the bacteria would look like if it hadn’t been contaminated and just left as agar. Having a sample of agar that wasnt exposed to any bacteria will provide a clear picutre of what grew on the agar upon feeding bacteria to it. 2. Why shoudn’t a student swab his or her mouth or cough onto an agar plate to initiate a culture? Even though most bacteria in the human body is harmless‚ if one was knowingly or unknowingly ill then harmful

beauty in times of ugliness in Liesel’s life. Some examples of this are‚ when Hans reads to Liesel after she has nightmares‚ Liesel reading (using the power of words to calm people down in the bomb shelter‚ when bombs are dropping‚ and Liesel reading Mein Kampf with Max in the basement. The reason why Hans‚ reading to Liesel after she has nightmares‚ is a great example of beauty in ugliness‚ is because of the fact that it shows how Hans cares for Liesel after she just moved to 33 Himmel st.

With as many losses as that‚ you must question the reasoning for it starting. Hitler took advantage of Germany feeling angry due to the Treaty of Versaille‚ and used historical anti-semitism to justify his horrific interpretation of Jews displayed in Mein Kampf‚ to create a lot of conflict that led to World War 2. Germany felt angered and wronged because of the Treaty of Versaille. In Article 231 the government agreed and signed the document accepting all the blame for World War 1 while many Germans

Identification of Unknown # 15 Abstract. One of the most fundamental differential staining techniques used in the study of bacteriology is gram staining. There are two main types of bacteria‚ gram negative and gram-positive. The purpose of this experiment was to perform a variety of tests to identify the bacteria contained in the unknown sample labeled number 15. The following are the tests that were used to identify the two different bacteria. The

The first test conducted on unknown bacteria 32 was the Gram stain. From this stain‚ unknown 32 was found to be a Gram-positive cocci. This test eliminated all possible Gram-negative bacteria‚ Gram-positive rods and Gram-positive spirillium. Next‚ the endospore test determined whether or not the Gram-positive bacteria contained endospores. With the use of malachite green‚ steam‚ and safranin it was found that unknown bacteria 32 did not contain endospores. This eliminated Gram-positive cocci Sporosarcina

bacteria uses citrate as a source of carbon‚ Simmon’s citrate agar was used as the medium on which the bacteria was grown. The Simmon’s citrate agar consists of sodium citrate as the source of carbon‚ ammonium dihydrogen phosphate as the source of nitrogen along with pH indicator such as bromothymol blue. Procedure: The Citratase activity was detected by inoculating the unknown bacteria on the slant surface of Simmon’s citrate agar. Followed by overnight incubation at 37°C. Day after the slant
