Students are introduced to 3 different methods to classify soils and determine their moisture and organic (carbon) content.
Soil classification uses the gravimetric method of placing soil samples in glass gas flasks or graduated cylinders with water, shaking it well and letting the particles fall out of suspension and determine boundaries between sand, silt and clay. These then are plotted on tri-linear soil classification diagrams.

AP Biology UNIT 6 Gene Expression 6.3 Transcription & RNA Processing Video
In AP Biology Unit 6.3, transcription is the process where RNA polymerase reads a DNA template strand to synthesize a complementary RNA molecule. In prokaryotes, transcription occurs directly in the cytoplasm and the mRNA can be translated immediately with little or no modification. In eukaryotes, transcription happens inside the nucleus and the initial RNA transcript must undergo RNA processing, including the addition of a 5′ cap, a poly-A tail, and splicing to remove introns. These modificatio
