Count the number of elementary bodies you see through the microscope (recall that elementary bodies stain green)‚ enter the number of elementary bodies in the field below‚ and then click Submit Data to display your results in the grid. After you click Submit Data‚ the slide will automatically be placed in the biohazardous waste disposal. You answered: 0 elementary bodies 16. Drag the next slide (patient B) to the fluorescent microscope. Count the number of

was observed using a microscope. The task was to observe and identify 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

1.0 INTRODUCTION: AISI 304L austenitic stainless steel is widely used as engineering materials due to its high strength and good corrosion resistance properties. However‚ AISI 304L stainless steel undergoes extensive wear and erosion when applied as components in aggressive environments such as petro- chemical and marine atmosphere [1]. Solid particle erosion is defined as the progressive loss of material from a solid surface due to mechanical interaction between the surface and some fluid entrained

Middelburg‚ credited with inventing the first microscope‚ which at the time was a tremendous increase in technology and allowed for detailed drawing‚ sketching‚ and recording. His microscope was very simple‚ hand-held‚ and consisted of three draw tubes with lenses inserted into the ends of the flanking tubes. The lens for the eyepiece was bi-convex and the objective lens was plano-convex‚ which was a very advanced compound design during this time period. His microscope was able to magnify objects up to three

Endospore and Capsule Cell Staining Allison Lui Partner: Mary Chagin BIOL-235 W07 Dr. Runco 2/10/15 Introduction The purpose of this lab is to learn what endospore and capsules are‚ and how to identify them under a microscope using capsule and endospore staining methods. Capsules are found only in select bacteria‚ and serve a protective purpose. Made out of sugars and proteins‚ they are antiphagocytic‚ which prevents other cells to engulf the bacteria through phagocytosis. It

Practical 1 - Investigation into size and scale of microscopic tissues This practical focuses on microscope technique and using graticules and stage micrometers to determine size and scale in biological cells and tissues. Intended learning outcomes By the end of this practical you should be able to: • Use a microscope fitted with an eyepiece graticule and stage micrometer • Calibrate the eyepiece graticule using the stage micrometer • Use the calibrated graticule to determine the actual
