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.
Rock that forms from the cooling and solidification of lava at Earth's surface. Intrusive igneous rock Rock formed from the cooling and solidification of magma beneath Earth's surface. Course-grained texture When large masses of magma solidify far beneath the surface, they form igneous rocks that exhibit this texture, where the crystals are roughly equal in size and large enough to be identified with the unaided eye.
