If a person is normovolemic and consumes a large quantity of a hyperosmotic solution, it will ________. If a person is normovole
Irina-Kira [14]

Answer:

cause cells to shrink due to an increase in the osmolarity of extracellular fluid.

Explanation:

Normovolemic describes the situation in which a living organism maintains a normal volume or amount of blood in the body.

A hyperosmotic solution can be defined as a solution having an increased level of osmotic pressure. Thus, when there's a greater amount of solute with respect to another solution in a membrane with close similarities, it is known as hyperosmotic solution.

Basically, hyperosmotic solution gives rise to higher difference between solutes and similar solutions.

Hence, when a normovolemic person consumes a large quantity of a hyperosmotic solution, it will cause cells to shrink due to an increase in the osmolarity of extracellular fluid i.e the total number of solute particles with respect to the concentration of a solution (Osm/L).

Why dose the amount of water in a river change during the year
Marizza181 [45]
Hello! 
The amount of water in a river varies for each particular area. Whether the area has been receiving rainfall or a drought. 
Seasons also play a role; if it's Spring, you may receive more rainfall and have a higher water levels. If it's Summer, you may experience a drought, causing lower water levels.
Although that was not very much information, I thought I'd provide a small bit of information. Hope it helps. :)
