MacConkey’s Agar (MAC) plates. After 48 hours of incubation‚ it was unclear that two different bacterial colonies had grown on my TSA plate. Only one type of colony was evident. However‚ it was apparent that I had successfully isolated two different bacterial species by examining my MAC and CNA plates. Only one type of colony had grown on my MAC plate indicating a gram negative species‚ which I chose to be organism A. Similarly‚ only a single type of colony had grown on my CNA plate‚ indicating a gram

15-20 million years. What Is It? Scientists have learned that the Earth’s crust is fractured into a series of "plates" that have been moving very slowly over the Earth’s surface for millions of years. Two of these moving plates meet in western California; the boundary between them is the San Andreas fault. The Pacific Plate (on the west) moves northwestward relative to the North American Plate (on the east)‚ causing earthquakes along the fault. The San Andreas is the "master" fault of an intricate fault

1. Summarize advances over time in determining the age of the Earth‚ including the importance of the discovery or radioactivity. Herodotus counted layers of earth near the Nile River in 450 B.C.E. The Bible was used in the Middle Ages to compute the age of the Earth. The 18th and 19th centuries brought a more scientific look into determining the age of the Earth by studying the salinities of the oceans‚ the rates of sedimentation‚ and models of cooling of different materials in order to calculate

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

side because the mountains block the flow of water to a certain degree. The mountains that define the whole park and offer a variety of life‚ along with the beauty that comes with it‚ were formed by the collision of tectonic plates. The North American plate and the Pacific Plate have been colliding for millions of years and they have shaped the unique terrain of Denali National Park. Glaciers have also left their mark on the land‚ making craters and valleys. The Park is made up of many types of rocks
