Question 13

It is sometimes jokingly said that you could study for your biology test by placing your textbook under your pillow at night and thereby learn by osmosis, as the knowledge would flow from the book to your brain while you slept.Aside from the obvious silliness of this claim, what is wrong with the use of the word "osmosis" in this context?

Accepted Answer

Osmosis specifically refers to the flow
