Dima020 [189]

Answer:

Pons.

Explanation:

Inside of our brainstem, there is a structure which is called the pons, which is present besides the medulla oblongata. The pons is a significant structure in the upper part of our brainstem. It controls breathing, communication between different parts of the brain, and as well as sensations such as hearing, taste, and balance.

Pons is that part of the brainstem which carries one-way communications that advise the cerebellum of voluntary motor activities initiated by the motor cortex.

If they gave IVs of pure water in the emergency room to people who are dehydrated, what would happen?
Zigmanuir [339]

Answer:

The correct answer is: <em>B. blood cells would be in a hypotonic solution, so water would rush into the cell causing it to expand and eventually burst</em>.

Explanation:

Cells have a certain solute concentration that produces an osmotic pressure of aproximately 300 mOsm. For that reason, IVs solutions must have a solute concentration which equals the cell osmotic pressure. That is usually acomplished by using an aqueous solution of NaCl 0.9% w/v or 5% w/v Glucose.

If an IV of pure water is administrated to a person, the blood cells will be in a hypotonic solution. That is, with a concentration lesser than the concentration inside the cells. Due to the difference in concentration, a net flow of water will be produced from the exterior to the cell interior. As the volume of the cell is increased, the cell membrane is damaged and eventually the cell will collapse.

One way that cells use water
elena-s [515]
<span>For instance, during the concentration of salt in water affects the rate of osmosis because it will determine how much water should be transported or excreted or to be taken in. The cellular process is keen to the salt concentration of its system thus making sure to maintain balance between the salt concentration the right amount of water must also be in its area of release for any expected occurences. </span>
<span>Osmosis then is the movement of water particles from which has water and from which has not and to provide it with the sufficient H2O.<span>
