Cual es la diferencia entre el agua de mar y el agua del consumo humano?

El agua salada es agua que contiene una cierta cantidad de sales. Esto significa que su conductividad es más alta y su sabor es mucho más salado cuando se bebe. El agua salada no es apta para ser utilizada como agua potable, porque la sal drena el agua de los cuerpos humanos. Cuando los humanos beben agua salada corren el riesgo de deshidratarse.

Explanation:

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
