Question

multiple-choice question
the water is forced in the opposite direction of natural osmosis by
applying pressure
adding sucrose to the water
squeezing it through tiny pipes
rewatch

Explanation:

Reverse osmosis is the process where water is forced against the direction of natural osmosis. This is achieved by applying pressure greater than the osmotic pressure. Adding sucrose would affect osmosis but not reverse it in this way. Squeezing through tiny pipes (like in some filtration) is not the mechanism for reversing osmosis direction as described here. The key concept is that pressure overcomes the natural tendency of osmosis to move water from low - solute to high - solute concentration, making "applying pressure" the correct answer.

Answer:

applying pressure
