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.

Which force primarily acts on a natural or artificial satellite to keep it in orbit around a planet
rjkz [21]

Answer:

Gravity

Explanation:

When its altitude is matched by the pull of the Earth's gravity, a satellite circles Earth. The satellite will fly off into orbit in a straight line or crash down to Earth without this equilibrium.

By juggling two things, a satellite retains its orbit: its velocity (the speed it takes to travel along a straight line) and the gravitational force on it that the Planet provides. To resist the greater gravitational force, a spacecraft orbiting closer to the Earth needs more velocity.

frozen [14]
In brain chemistry, synapses are very important. Synapses have a number of different forms but have two basic varieties:. excitatory and inhibitory. Excitatory synapses make it more likely that a neuron will send its message to other neurons, whereas inhibitory synapses make it less likely that a neuron will send its message.
