There is one true evolutionary history of life, and whether we will actually ever know it is not likely. Moisture content is a key element of describing flow through unsaturated soils. By contrast, at high field frequencies, the active group fails to develop the alignment and tends to behave like a set of independent individuals even in the presence of interactions. At the same time, smaller schools may have less diverse course offerings and fewer opportunities for financially supported research.

It is important to challenge students to view their mistakes or unexpected results as potentially helpful. Scientific studies are most often riddled with problems that must be addressed.
