if antimicrobial concentration increases‚ then the zone of inhibition will increase because the higher the concentration‚ the more the antimicrobial will disinfect the area of bacteria and thus the zone of inhibition will increase.The results of the lab do support my hypothesis. Paragraph 2: My antimicrobial was bleach. Bleach contains hypochlorous acid which “causes bacterial proteins to unfold and stick to one another‚ making them nonfunctional and leading to cell death”(publications.nigms.nih.gov)

Carbohydrate Lab Report Introduction Qualitative identification of a substance is of significant importance in chemistry. Physical constants such as melting points have traditionally been used by organic chemistry for identification of unknown compounds. As for inorganic substances‚ the precipitation of a solid‚ results of a flame test‚ or the formation of a colored substance could all be keys to identifying a sample. Chromatography and spectra are amongst the newer techniques

Lab Report 1/28/13 Observations of Chemical Changes Page. 14 Objectives: The objectives of this experiment are: 1. To observe some properties of chemical reactions 2. to associate chemical properties with household products Background Information: Chemical changes are often accompanied by physical changes. Three that you should not see in this lab are changes in temperature‚ presence of a flame‚ and evolution of light‚ as when as firefly glows. Three physical changes that indicate a

Wanni Lin Biology 110 March 2‚ 2015 DNA Lab BACKGROUND In this laboratory experiment‚ students were introduced to DNA electrophoresis. DNA electrophoresis is an instrument that many forensic scientists use to get a DNA fingerprint as an evidence for crimes. Not only can it be used for forensic science‚ people can use this for paternity test‚ as well as look for evolutionary relationships among organisms. Agarose is used to make the gel that the DNA fragments are going into. Since DNA particles are

SCIE211 Phase 2 Lab Report Title: Speciation Instructions: You will need to write a 1-page lab report using the scientific method to answer the following question: • What would happen if a species within a population were suddenly split into 2 groups by an earthquake that creates a physical barrier like a canyon? When your lab report is complete‚ post it in Submitted Assignment files. Part I: Use the animated time progression of speciation to help you write up your lab report. Part II: Write

started immediately with concomitant formation of a brown precipitate of crude acetanilide. 50ml of water and a magnetic stirring bar were added to stir the reaction mixture and the flask was heated on a magnetic stirring hot plate until all of the solid and oil were dissolved. The temperature of the reaction mixture at this point was close to 100°C‚ the boiling point of water. A few milliliters of hot solution was removed from the flask with a disposable pipette and placed in a test tube. The test

NaOH(aq)‚phenolphthalein indicator‚ commercial vinegar (5% acidity)‚ distilled water Procedures: Part1: The density of the commercial vinegar was found. A small breaker was put on an electronic balance and the reading of the balance was set to zero gram. 10.0cm3 of the commercial vinegar was pipetted into a small beaker. The vinegar was weighed with an electronic balance. And the density of the vinegar was known as 1gcm-3. Part2: The commercial vinegar was diluted 10 times. A 25.0cm3 pipette
