INTRODUCTION Microorganisms such as bacteria‚ fungus‚ mold‚ and yeast are present and common in almost every environment on earth. The normally microscopic organisms can easily be seen using differing types of agar‚ which creates an ideal environment for the organisms to form colonies‚ which are groups of hundreds of organisms that can be seen with the naked eye. In order to see individual microorganisms‚ it is necessary to use the magnification of a high-powered microscope. These techniques

The mouth-watering aroma flooded my nose as I entered a room full of patrons and food. I was mesmerized by the atmosphere of the restaurant. The sound of the music mixed with the clashing of utensils and plates‚ and the sizzling sound of food being cooked by professionals was all too familiar. It was here where my family had our very first high class dinner. As my parents were ordering from the menu‚ I was witnessing the chef preparing beef. He first placed the beef on a pan and poured

An agar plate is a Petri dish that contains a combination of agar and nutrients that help microorganisms grow. The proper method of setting microorganisms on an agar plate is know as “streaking”. In order to streak‚ the microorganisms are placed on a sterile swab or metal wire‚ which is then dragged lightly against the agar solution‚ leaving

result indicated that my unknown was negative because no bubbles formed when I placed a loop of the organism into hydrogen peroxide. The next step was to examine a blood agar plate to examine the colonial morphology of hemolysis ‚ my organism produced gamma hemolysis on the blood agar because there was no hemolysis on the plate after 48 hours incubation period. After examining my unknown for hemolysis I set a series of five experiments: Bacitracin SX CAMP Enterococcosel 6.5% NaCl My unkown

basic categories of rocks include igneous‚ sedimentary and metamorphic. The rock cycle is largely driven by lithospheric plate movements which cause oceanic crust creation and subduction with its associated melt and igneous rock formation‚ and uplift with it’s associated metamorphism‚ along with exposure and erosion from climatic conditions due to the exposure. Plate tectonics (from the Late Latin tectonicus‚ from the Greek: "pertaining to building” is a scientific theory that describes

As Bangladesh is the world’s most densely populated area‚ any future earthquake shall affect more people per unit area than any other seismically active regions of the world. 2. Causes of Earthquake 2.1. Plate Tectonics An earthquake is the violent shaking of the Earth caused by a sudden movement of rock beneath its surface. Rocks respond to stress (squeezed or pulled apart) near the Earth ’s surface

hour. 3. FORMATION OF THE SWISS ALPS The Swiss Alps are a mountain range formed by the convergence and collision of the European and African tectonic plates approximately 100 million years ago. As a result of this collision‚ the Tethys Ocean basin gets pushed upward by the African tectonic plate and into the Eurasian tectonic plate. The bottom of the Tethys Sea experiences enormous pressures‚

Mount Saint Helen’s Volcano‚ part of the cascade mount range‚ is associated with the subduction zone of the Juan du Fuca plate into the North American plate‚ as is most of the volcanism in this mount range (USGS Geology & History). The eruption intensity is normally quite explosive but Mt. Saint Hellen’s has experienced the peaceful one on occasion (USGS Geology & History). With frequent eruption every couple hundred years (rough estimate at best)‚ Mt. Saint Helen’s is the most active volcano of
