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.
Let's start with igneous rocks. Igneous rocks form when melted rock, or magma cools and hardens. Sometimes the igneous rocks form in the ground (intrusive igneous rocks), and sometimes they form outside of the ground (extrusive igneous rocks). Rocks deep in the earth melt and form molten, or melted, rock called magma.
