This bacteria was first discovered in the late 1800âs. Since then, it has had a long history of use in scientific research. It is the most widely used organism in molecular genetics. Part of the reason E. coli is commonly used in scientific research is that it is easy to grow in a lab. The factors that make E. coli easy to grow are its simple nutritional needs, fast growth rate and its moderate maintenance requirements.
What kind of igneous rock texture results from slow cooling magma? A coarse grained texture, referred to as a phaneritic texture, will be the resultant igneous rock texture. The slower the magma cools the more time minerals have to crystall â¦ ize and thus grow bigger.
Igneous rock is formed through the cooling and solidification of magma or lava. Igneous rock may form with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.ypically, the melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. Over 700 types of igneous rocks have been described, most of them having formed beneath the surface of Earth 's crust.
