DIFFERENT TYPES OF AGAR Mac Conkey‘s Agar plate MacConkey (also McConkey) agar is a culture medium designed to grow Gram-negative bacteria and stain them for lactose fermentation. It contains bile salts (to inhibit most Grampositive bacteria‚ except Enterococcus and some species of Staphylococcus)‚ crystal violet dye (which also inhibits certain Gram-positive bacteria)‚ neutral red dye (which stains microbes fermenting lactose)‚ lactose and peptone.

Plate Tectonics: An Essay By: Grace Park Science 9 Mr. Achor 11-22-11 In the early 1900’s‚ scientists began to ask questions about the earth and it’s continents. Why are the same fossils found on opposite sides of the globe? Why do South America and Africa seem to fit together like two pieces of a jigsaw puzzle? Some scientists went to rather extreme measures to explain these strange phenomenons. Others took the time to come up with detailed theories

The Printing Press There have been many important inventions over the past millennium. Many of them have helped shape society into what it is today. None however have contributed as much to the world as the printing press has. The printing press was invented in the year 1440 by Johann Gutenberg of Mainz‚ Germany. The printing press consisted of a large press which held plates where movable type could be inserted to spell out entire books page by page. The press was either operated by a large

Heat Exchanger Rupture and Ammonia Release The CSB Case Study on the incident‚ examines the events leading up to the rupture of the heat exchanger and the ammonia release‚ and the corresponding emergency response to the event. It is clear that there were many failures and opportunities to correct and prevent this incident from occurring. As they performed their investigation‚ they were able to identify several direct‚ contributing‚ and root causes‚ although they don’t specifically designate

been linked to discomfort in muscles following bouts of athletic performance. Myofascial release is often used as an aid to help alleviate this discomfort. This‚ however‚ is often utilized only as a post-exercise treatment and limited research has been done for its pre-exercise benefits. Of the literature available‚ there is a strong disconnect to the observed benefits for pre-exercise myofascial release‚ especially from foam rolling. The purpose of this study is to reconcile the conflicting

CONSERVATIVE PLATE MARGINS (TRANSFORM FAULTS): When two plates slide past each other they create a conservative plate margin. The relative movement is horizontal‚ and classified as either sinistral (moving to the left) or dextral (moving to the right). Along these margins crust (lithosphere) is not being destroyed by subduction‚ neither is it being created. There is no melting of rock‚ and‚ therefore‚ no volcanic activity or formation of new crust. Despite the absence of volcanic activity‚ these

Parole Release Should parole release be abolished? This is one of the most talked about topics in the criminal justice field today. Many people feel it is time to do away with parole‚ while others are fighting to keep it around. There are pros and cons to both sides of the argument‚ all of which are very convincing. One of the strongest arguments against the parole system is the overpopulation problem in most prisons. Between 1986 and 1991‚ prisons have seen a 41% increase in the population of

“The extent to which tectonic processes represent hazards depends on when and where they are experienced.” Tectonic hazards are dangers caused by the movement of the earth’s plates. The majority of hazards represent by plate tectonic occur at plate margins where two plates meet. These natural processes become hazardous when they affect people and cause material losses such as the destruction of infrastructure as this inhibits sustainable development. These hazards can be reduced depending on when

events are major pieces of evidence towards proving that plate tectonics theory is valid (40 marks) The theory of plate tectonics states that the Earth’s lithosphere (top layer of the Earth’s crust) is split up into rigid sections called plates that are moving relative to one another as they move on top of the underlying semi-molten mantle. These plates are either continental‚ The North American Plate‚ or oceanic‚ The Nazca Plate. Tectonic plates are powered by convection currents‚ which is the circular
