During osmosis, a statement which correctly describes the movement of water across a selectively permeable membrane is: 3. Either of these descriptions is correct and equivalent.
<h3>What is osmosis?</h3>
Osmosis can be defined as a process which typically involves the movement of a solvent molecule such as water through a selectively or permeable membrane from a region of high concentration to a region of lower concentration.
This ultimately implies that, the process of osmosis can be illustrated by the movement of water into root hair cells because they are used by the plants to absorb water from the soil.
In conclusion, the movement of water of from high water concentration to low water concentration and from low solute concentration to high solute concentration are statements which correctly describes the movement of water across a selectively permeable membrane during osmosis.

Complete Question:
Which of the answer choices correctly describes the movement of water across a selectively permeable membrane during osmosis.
1. The water will move from high water concentration to low water concentration.
2. The water will move from low solute concentration to high solute concentration.
3. Either of these descriptions is correct and equivalent.
At first situation, ratio = x/y = 1/5
5x = y -------Equation (i)
Now, after adding 5 more red, it is = x + 5 / y+5 = 1/3
y+5 = 3(x + 5)
y + 5 = 3x + 15
y - 3x = 15 - 5
Substitute the value of y from equation (1),
5x - 3x = 15 - 5
2x = 10
x = 10/2
x = 5
