Answer: The correct answer for the fill in the blank is osmosis.
Osmosis is defined as the movement of solvent (like water) from a region where the concentration of solute is lower to a region where the concentration of solute is higher though a semipermeable membrane.
In other words, it is the water movement from an area where its ( water ) concentration is higher to an area where its concentration is lower.
This process does not require any energy as water is moving along the concentration gradient.
It is positive because our body needs 37C to perform metabolism properly so sweating helps to balance the temperature. We lose water but water is generally provided to body by drinking or any food that has water.
