Answer : Salinity tolerance
Explanation :
The important characteristics for the plants which are found in salt water wet lands is salinity tolerance.
Salinity tolerance is the salt tolerance of crops in the wet lands which gives maximum salt level that a crop can tolerate without losing its productivity.
Although it may get affected negatively at higher levels of exposure. The salt level is often measured as the soil salinity or else the salinity of the irrigated water.

endothermic, causing an increase in the kinetic energy of the water molecules.
(exothermic, causing an increase in the kinetic energy of the water molecules.)
exothermic, causing an increase in the kinetic energy of the solute particles.
Answers
The reaction is exothermic, causing an increase in the kinetic energy of the water molecules.
• In a calorimeter when the reaction takes place, and there is an increase in temperature recorded in the thermometer, it shows that the reaction is emitting heat to the surrounding, and such kind of reactions is known as exothermic reaction.
• With the mixing of aqueous solution of HCl and NaOH the temperature of the solution increases, this shows that the kinetic energy of the water molecules increases. As, kinetic energy is directly proportional to the temperature.
• With increase in temperature, the collision or vibration of molecules increases, thus, there is an increase in the kinetic energy between the molecules.
Thus, the reaction is exothermic, causing an increase in the kinetic energy of the water molecules.
