When an environment is hypotonic, the cell has more solute so solvent move from outside the cell to inside causing the cell to swell.
WHAT IS TONICITY?
- Tonicity is the ability of a solution to induce water loss or water gain in a cell. A solution can either be; hypertonic, hypotonic or isotonic
- A hypertonic solution has more concentration of solute than its surroundings while a hypotonic solution has less concentration of solute compared to it's surroundings.
- If a hypotonic solution has less solute, this means that it will have more solvent (water). Based on the principle of osmosis, water moves from a region of high concentration to region of low concentration.
Hence, water will move into a cell that is located in a hypotonic environment, causing it to swell.

The missing options of the question are:
permissiveness
synergistic effect
antagonism
additive effect
The correct answer is "permissiveness",
In biology, a permissive effect is defined as the effect that one hormone has enabling that a second hormone to exert its biological activity. Thyroid hormone has a permissive effect on the hormone epinephrine, by synthesizing ß adrenergic receptors, it enables the hormone epinephrine binds to them and cause the cells of the bronchioles to dilate.
