the different types of cell‚ cytoplasmic streaming‚ and plasmolysis of Egeria densa. First‚ the microscope was examined and investigated to master the use of the equipment. A microscope slide grid which was on the slide glass was required to be seen clearly using 4x‚ 10x and 30x. During the latter part of the experiment‚ the Egeria densa was observed using the microscope to understand the use of microscope by actually examining Egeria densa. The different types of cells of Egeria densa that were

Lab Report The Effect of Resting on Clothespin Squeezing. Hypothesis: If you rest then the clothespin squeezing rate will increase. Materials:- Clothespin Clock Sneakers Procedure: Separate class into two groups (exercisers and resters). Exercisers will do jumping jacks for a minute. Exercisers and registers will squeeze clothespin for a minute Repeat steps two and three. Total of three trails. Precaution: Shoes must be tied. Space between exercisers. Healthy exercisers

this unknown lab report various test were performed to differentiate microbes from each other and to compare metabolic and biochemical process. The gram stain distinguishes between Gram positive and Gram negative bacteria based on the composition of the cell wall. The Gram stain procedure distinguishes between Gram positive and Gram negative groups by coloring these cells red or violet. Gram positive bacteria stain violet due to the presence of a thick layer of peptidoglycan in their cell walls‚ which

Microbiology Laboratory Report Identification of Unknown Bacteria 03/10/05- 04/01/05 Authors: Richard Hendricks‚ Jessica Prebish; NMU Abstract: Broth culture 16 was randomly selected by our group and subjected to qualitative tests for taxonomic identification. The culture did appear homogenous throughout the testing period and is currently retained by Northern Michigan University’s department of Microbiology. We suggest that culture 16 is an example of Escherichia coli. Background: Techniques

Lauren Sullivan Plants Imperfections Abstract The purpose of this experiment was to plant different crosses and observe the different phenotypic ratios the plants present. The procedure of this experiment was plant six different crosses and water them correctly so that we could observe the different phenotypes and compare them to Mendel’s proposed ratios. Mendel‚ who had studied peas‚ did a similar experiment and came up with specific ratios that a monohybrid and dihybrid cross should show. His

LAB Report #3 Introduction: In this lab we have focus on Isolation of bacteria from environment. Microorganisms are found throughout the environment: in the air and water; on the surface of any object such as clothes‚ walls‚ furniture; in soil and dust; and on and in our own bodies (skin and mucous membranes). In order to demonstrate the ubiquity and diversity of microbes in the environment‚ samples from immediate areas of the environment and/or from your body will be obtained and cultured

Cell Membrane Transport ZOOL 2011.19 A. Introduction: Cells are the most significant building blocks of all living things. They are also the tiniest living organisms in the human body which provides structure for the body and intake nutrients that become energy. Cell membranes control what goes in and out the cell‚ it protects it. The lipid bilayer describes the membrane of both animal and plant cells where the properties that make up phospholipids are very important
