Fluid and electrolyte balance is maintained through the process of translocation. What specific process allows water to pass through a membrane from a dilute to a more concentrated area?

Osmosis

Explanation:

Osmosis is the process of movement of water molecules from the region of its higher concentration (hypotonic) to that of the lower concentration (hypertonic).

Here, two solutions of different solute concentration are separated by a membrane that allows the movement of water molecules through it. Osmosis is a passive movement and does not require an input of energy as it is driven by the concentration gradient.
