  • How Different Ph Levels Affect The Population Growth Of Yeast

    1180 Words  | 5 Pages

    Introduction Through this lab, we were trying to solve the problem of how different pH levels affect the population growth of yeast, which was based on the mm of carbon dioxide produced. Through this, our independent variable was the pH level of solution added to the test tube of yeast and sugar. Our dependent variable was the mm of CO2 produced, indicating population growth. For this lab, the proper control was a test tube with the yeast and sugar but no pH solution added. This was useful to

    Lab Report 1 Purpose To develop an understanding of the metric system and use it to measure common objects. To also learn about how to report uncertainty in your measurements. Lab Observations Most flat objects do not consist of uncertainty. When we measured round objects, because of its shape, it contained uncertainty. Lab Answers 1. Using a metric ruler, determine the length of the items in Table 1.1 below: In the final column, you are to estimate your measurement precision. To do

  • The Effects Of Microbial Cell Culture On Human Development Essay

    1864 Words  | 8 Pages

    INTRODUCTION MICROBIAL CELL CULTURES TECHNIQUES Microbial cultures are foundational and basic diagnostic methods used extensively as a in research tool in molecular It is important to have pure culture isolation. A pure culture is a population of cells as a multicellular organisms growing in the absence of other species or types. A method in which microbes are cultured by letting them reproduce in the predominated culture media under controlled laboratory conditions,

  • Natural and Sexual Selection of Vestigial and Wild Type Drosophila Melanogaster

    rotten bananas, and yeast were used. The bananas chosen to be an accelerant for the growth of the yeast and were frozen so they would be easier to cut. The yeast was used because the drosophila melanogaster prefer this as a food source.  The vestigial and wild type flies were sexed (to determine their sex), sorted, and counted.  An initial population size of 100 total flies was decided so that it would be easier to determine the phenotypic percentage of the total population. Fly paper was placed

    Da Ye Kang Population Design Lab Ms. Chow 6th May 2014 Research Question/ Aim To investigate how the change of the temperature on the surface of a glass jar, in conditions of 18°C(±0.5),20°C, 22°C, 24°C, 26°C, 28°C , 30°C respectively, affects the population growth of Drosophila melanogaster for 17 days. Independent Variable Seven different temperature conditions of 1L glass jar: 18°C(±0.5), 20°C, 22°C, 24°C, 26°C, 28°C, 30°C. Dependent Variable The number of adult Drosophila melanogaster (±1

    changes in their life’s. There are trials of treating and controlling HD, Question 2 : Characterising Yeast Mutants. Wild-type haploid or diploid yeast strains ferment sugar to form ethanol, but the yeast are somewhat sensitive to ethanol and this sensitivity limits production of ethanol to ~6% weight by volume (w/v). The Chapelcross brewery mutated their haploid production strains of yeast and found three mutant strains that are tolerant to ethanol (up to ~15%). They plan on exploiting these

  • Microbial Diversity Of Soil And Determine The Population Density Of Bacteria, Actinobacteria, And Fungi Essay

    1937 Words  | 8 Pages

    Soil samples were collected from a construction site in North Norman and the duck pond at the University of Oklahoma. To demonstrate the microbial diversity of soil and determine the population density of bacteria, actinobacteria, and fungi, the samples were cultured in the laboratory. Serial dilutions of the samples were prepared and grown on different growth media for selective culturing of the three groups. Following incubation of the plates at 37C for two days then at 4C for five days, it was
