PPT-CONTINENTAL DRIFT

In 1812 Alfred Wegener presented his scientific theory called Continental Drift It was based on his belief that the continents had drifted apart from one another Pangaea Wegener s hypothesis was that all the continents had once been joined together in a single landmass and have since drifted apart.

Why does it matter?. “An antidepressant that brought relief to only seventy percent [of patients] would be a valuable treatment if it did so in one week and had few side effects. Unfortunately, given the current clinical trial methods and placebo-response rates, such an antidepressant, regardless of its true efficiency, would not have more than a fifty percent chance of looking better than placebo.
