Heart cells require a certain balance of sodium and potassium ions to function. The blood, which is approximately 83% water, car
ries these two types of ions to the heart. The property of water that allows it to dissolve substances to carry to the heart is its Cohesion Polarity Adhesion Specific heat
Salinity, along with temperature, determines the density of seawater, and hence its vertical flow patterns in thermohaline circulation. 2. Salinity records the physical processes affecting a water mass when it was last at the surface. Hope this helps!
