USABO EXAM QUESTIONS AND ANSWERS Eukaryote - ANS An organism whose cells contain complex structures enclosed within membranes. The defining membrane bound structure that sets them apart from prokaryotic cells is the nucleus or nuclear envelope within which the genetic material is carried. All large complex species are eukaryotes, including animals, plants and fungi. Euchromatin - ANS This shows as pale areas in the nucleus under electro magnification. It is a less densely packed for...

Why is myelin important in the nervous system? A. It allows signals to travel faster along axons because depolarization occurs only at myelinated locations. B. It allows signals to travel faster along axons because depolarization occurs only at nonmyelinated locations. C. It bundles the dendrites of adjacent neurons together. D. It increases capacitance across the cell membrane, which helps electrical signals to leave the axons. E. It traps neurotransmitters, increasing their concentratio...
