performed this test‚ the initially slant for unknown microorganism #17 is important. For this lab‚ two identical slants are used for two reasons. Firstly‚ the slant can be used to make sure that there is no contamination from the Nutrient Agar plate. Secondly‚ the second slant will become a stock culture to prevent the shortage of slants during performing the series of tests. Kliger’s Iron Agar tests can be used to determine multiple characteristics of unknown microorganism #17. Kliger’s Iron Agar slants

Abstract: Protecting biological diversity is defined based on analyzing the cladistic information. In this lab the null hypothesis was examined through interpreting constructed cladograms. A cladogram of five mammalian species include domestic dog (canis familiaris)‚ the Virginia opossum (Didelphis virginiana)‚ the domestic horse (Equus caballus)‚ the domestic cat (Felis cattus) and the white-tailed deer (Odocoileus virginianusis is generated based on the morphological feathers of these mammalian

Cogswell ENG2D- 02 October 15‚ 11 Fear of the Unknown People are quick to judge‚ fear and hate the unknown. Some people may not admit it but everyone is plagued with the tendency to let our imagination take over reality and turn it into the unknown. An excellent example of this is in William Golding’s novel Lord of the Flies. All the boys in Golding’s novel are totally indulged in the theme of fear of the unknown. All of these have some “unknown” element to them; they can’t see in the dark‚ they

The melting point range is defined as the span of temperature from the point at which the crystals first begin to liquefy to the point at which the entire sample is liquid. This data can be tabulated experimentally through multiple trials for an unknown and referenced against the chemistry literature for a known compound. In Macroscale and Microscale Organic Experiments‚ 5th ed‚ Williamson notes that most pure organic solids will melt repeatedly over a narrow temperature range of 1°C. As a measure

LAB#: 20 SKILL: Planning and Designing OBSERVATIONS: A student is given a small beaker containing an unknown salt‚ x. The salt is crystalline‚ deliquescent and colorless. The student is asked to perform test and observation on the salt to determine the cation and anion present. HYPOTHESIS: Perhaps by using the flame test or reacting salt x with NaOH‚ or NH4OH the cation could be distinguished by observing the color changes or solubility while reacting salt x with H2SO4 or a mixture of copper

The poem the unknown citizen written by w.h Auden portrays from the point of view of the government what or how an ideal citizen should look like. This piece is written in third person omniscient to project a non-bias perspective and that way transmit the “truth” without being affected by feelings or personal point of views. Moreover at the end of the poem the author makes a relevant turn which effect is making the reader question himself if what was depicted before is the right thing‚ if that ideal
