Premium Osmosis Chemistry Concentration
The movement of water down its osmotic gradient across a selectively permeable membrane is known as osmosis. The difference in the concentrations of solutes on either side of the membrane results in the establishment of an osmotic pressure. Water follows the direction of solutes‚ this means that in the event where there are more solutes outside the cell than there are inside the cell‚ water will move from the inside of the cell to the outside in order to establish water balance. When a cell is placed

TOK essay – November 2012 * “There are no absolute distinctions between what is true and what is false.” “Everything we hear is an opinion‚ not a fact. Everything we see is a perspective‚ not the truth.” Marcus Aurelius The quotation above explains the claim that is discussed in this essay; weather truth and falsehood can be distinguished.
