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.
Seafloor spreading occurs along mid-ocean ridges. Mid-ocean ridges  are large mountain ranges on the ocean floor. The shifting in the  rock causes the seafloor to spread and â¦ allows magma to bubble and  form more mountains on the ocean floor.Eccles-Jordan Trigger Circuit.eafloor spreading is the extension of oceanic lithosphere that  occurs where two oceanic plates are moving apart.
