The cell would increase the production of salt

|
The cell would decrease the production of salt.

Detailed explanation-1: -Due to environmental changes, the water concentration outside of a cell becomes lower than the water concentration inside of the cell. How would the cell most likely respond to maintain homeostasis? The cell would decrease the production of salt.
Detailed explanation-2: -If a cell is in a hypertonic solution, the solution has a lower water concentration than the cell cytosol, and water moves out of the cell until both solutions are isotonic. Cells placed in a hypotonic solution will take in water across their membranes until both the external solution and the cytosol are isotonic.
Detailed explanation-3: -The cell has higher water concentration, which means it has less solute concentration than the surrounding medium. Such, solution is said to be hypertonic. In such a case, the water molecules move from inside to the outside of the cell through the cell membrane.
Detailed explanation-4: -In passive transport, substances move from an area of higher concentration to an area of lower concentration in a process called diffusion.
Detailed explanation-5: -Osmosis: This is the hydrostatic force acting to equalize the concentration of water on both sides of the membrane that is impermeable to substances dissolved in that water. Water will move along its concentration gradient.
