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 textures include the rock textures occurring in igneous rocks. Igneous textures are used by geologists in determining the mode of origin igneous rocks and are used in rock classification.yroclastic (pyro = igneous, clastic = fragment) textures occur when explosive eruptions blast the lava into the air resulting in fragmental, typically glassy material which fall as volcanic ash, lapilli and volcanic bombs.
