OPCs are highly bioavailable, can cross the blood-brain barrier, and have no known toxicity or side effects. Doses used in studies range between 50-300 mg a day. OPCs are an easy way to get an edge on health!
The idea that the seafloor itself moves (and carries the continents with it) as it expands from a central axis was proposed by Harry Hess from Princeton University in the 1960s.t the Mid-Atlantic Ridge (and in other areas), material from the upper mantle rises through the faults between oceanic plates to form new crust as the plates move away from each other, a phenomenon first observed as continental drift.
The typical rates of seafloor spreading is 5 centimeters per year.  Seafloor spreading is a process that occurs at mid ocean ridges. b. Knowing the various dates for the magnetic pole revesals, and the distance from the location of a known reversal site to the ocean ridge.
