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.
1 Igneous Rocks â Lava Textures Lava is an EXTRUSIVE form of Igneous Activity It represents molten rock that has been erupted or extruded onto the earthâs surface from volcanoesLava generally cools quickly (overmonths/years/decades) depending on the thickness of the flow.2  2. Lava Textures-aa Aa lava has a surface made of sharp, angular and jagged blocksof basalt. 2  The cooled surface layer breaks up into these fragments as molten lava continues to flow beneath. 3  8.
