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 Rocks Igneous rocks form from the solidification of magma (molten rock). A reminder: magma is molten rock beneath the Earth s surface and lava is magma that is on the Earth s surface.The main characteristics of an Igneous rock are crystal size (grain size) and texture. The crystal size and texture of an igneous rock is dependant on where in the earth the rock formed.edimentary rocks are formed from the burial/compaction and cementing of earth materials. These earth materials (sediments) are carried by natural agents such as wind, water, and glaciers and then are deposited on land or underwater.
