yeast and mold in a sample. It counts the number of colonies produced by a very dilute suspension of bacteria on an agar plate and to observe the differential staining behaviour of the living bacteria. This involves counting the colonies produced by viable cells under favourable growth conditions. Some techniques needed before the viable count‚ like pour plate method‚ spread plate method and most probable number method. The viable count is very specidic‚ as it represents the number of colony forming

Aseptic Technique and Streak Plates Purpose The purpose of this exercise is to learn aseptic technique procedures and there importance and also to learn to isolate colonies using the streak plate technique. Introduction Bacteria are inoculated (introduced) and cultured (grown) in the laboratory for test studies to determine their morphology (the shape‚ size‚ arrangement‚ and internal structures) and pathology (ability to cause disease). Inoculation has to be performed without adding other microbes

His theory found more scattered support after his death‚ but was still rejected by most geologist. It was not until the 1950’s when increased exploration

Course Syllabus College of Natural Sciences GLG/150CA Version 1 Exploration of Earth Sciences Course Description This course focuses on the dynamic forces impacting Earth’s environment. It is a study of the major constructs in geology‚ oceanography‚ meteorology‚ and astronomy collectively called Earth science. A scientific approach will be used in orienting students to develop an understanding of the interconnectivity of each of these sciences. Policies Faculty and students/learners

able to penetrate our atmosphere and cause immense damage (Goulding). The damage a large meteor would cause would be catastrophic. Several ramifications that probably dont come readily to mind are the effects on the human body‚ thermodynamics and plate tectonics. Without friction‚ many functions of the human body would not work. Procreation would be impossible as friction is necessary for the male orgasm. Digestion would be impossible as the human body uses friction to digest and move food throughout

between the crust and mantle. Crusts and Plates The crust is not the same thing as the plates of plate tectonics. Plates are thicker than the crust and consist of the crust and the shallow mantle just beneath it; the two-layered combination is stiff and brittle and is called the lithosphere ("stony layer" in scientific Latin). The lithospheric plates lie on a layer of softer‚ more plastic mantle rock (the asthenosphere or "weak layer") that allows the plates to move slowly over it like a raft in thick

set of natural processes that lead to the formation and transformation of igneous‚ sedimentary‚ and metamorphic rocks. The rock cycle shows that each type of rock can change in a certain way to form another. The driving force of the rock cycle is plate tectonics. The transition to igneous is when rocks are pushed deep under the earth’s surface and may melt into magma‚ if there is no condition for the magma to stay in a liquid state‚ it will cool and solidify into an igneous rock. The three main

Evidence for plate tectonics (http://www.bbc.co.uk/schools/gcsebitesize/science/aqa/oils/changesrev3.shtml) b About fifty years ago‚ new evidence convinced scientists that the Earth’s crust is made up of tectonic plates that are moving very slowly. Give two pieces of evidence that have helped to convince these scientists that the tectonic plates are moving. The movement and separation of continents and Earthquakes are a result of plate movement. They are the sudden
