Countercurrent exchange is evident in the flow of water across the gills of a fish and the blood within those gills. Countercurrent exchange is a mechanism occurring in nature and mimicked in industry and engineering, in which there is a crossover of some property, usually heat or component, between two flowing bodies flowing in opposite directions to each other. Biological countercurrent systems may be downhill exchanges and hairpin multipliers.
DNA Not The Same In Every Cell Of Body: Major Genetic Differences Between Blood And Tissue Cells Revealed. Summary: New research calls into question one of the most basic assumptions of human genetics: that when it comes to DNA, every cell in the body is essentially identical to every other cell.Jul 16, 2009
Answer:
C) is prevented due to growth-inhibiting proteins of oligodendrocytes
Explanation:
Oligodendrocytes are the neuroglial cell and mainly serve to support neurons. These cells also produce a myelin sheath around axons of neurons of the central nervous system. Axons in the CNS display little regrowth or neurogenesis. Inhibition of regeneration is due to several factors such as the absence of a neurolemma and an inhibitory influence of the oligodendrocytes on axon regrowth. For the purpose, the oligodendrocytes produce growth-inhibiting proteins. Axons in the CNS are myelinated by oligodendrocytes and this myelin is one of the inhibiting factors in the regeneration of neurons.
C, the apple may potentially fall due to gravitational pull.
Answer:
The serum protein electrophoresis (SPEP) test measures specific proteins in the blood to help identify some diseases. Proteins are substances made up of smaller building blocks called amino acids. Proteins carry a positive or a negative electrical charge, and they move in fluid when placed in an electrical field. Serum protein electrophoresis is used to identify patients with multiple myeloma and other serum protein disorders. Electrophoresis separates proteins based on their physical properties, and the subsets of these proteins are used in interpreting the results.

Explanation:
thats what I know about it, I would need more of a question to answer like do you mean what it means, what it does, or what's it about ?
