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

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

Practical guide to detection and identification of Phytophthora Leaf blight A number of Phytophthora species cause leaf blight. These include: P. infestans on potato and tomato; P. palmivora on a large number of tropical fruit species including rubber‚ durian and macadamia; and P. colocasiae on taro. These blights on leaves are first seen as small flecks but within 3-5 days they expand to produce large lesions. Initially‚ infected tissue is water soaked but becomes necrotic (brown or black) in

ASEPTIC TECHNIQUES AND SOURCES OF MICROBIAL CONTAMINATION. Introduction The spread of infections has come to a point where it has become catastrophic. Aseptic technique is the method used to prevent contamination of infections. It is widely used in hospitals‚ pharmacy‚ and pharmaceutical industries and in laboratories. Different establishments have come up with more ways to improve infection control. In hospitals health care acquired infections are costing the NHS £1 Billion a year and

when volcanic islands collided in the south west of America‚ where the North American plate is now. Mountain building occurred about 75 million years ago when the uplift of almost 2 miles in the region‚ (called a Laramide orogeny event) started and created the Colorado Plateau. The rocks in the Grand Canyon were igneous or sedimentary rocks before the collision of tectonic plates. The collision pushed the plates under the earths crusts. The rocks recrystallized under high temperature and pressure
