Answer:
D
Explanation:
A hypotonic solution means it is less concentrated in relations to the other solution – in this case the patient’s cells. The electrolytes that balance osmotic pressure in the body are sodium, potassium, chlorides, calcium, and etcetera. The IV needs to have less electrolytes so that when the IV is injected into the patient’s blood the water can move into the cells by osmosis. Osmosis continues until the cell cytoplasm is in osmotic equilibrium with the blood. It is imporant, therefore, to have the right electrolyte balance in the IV solution otherwise the cell will over-hydrate and begin lysing – especially if the kidneys of the patient do not rid excess water fast enough.

A at right angles
•
The movement produces oscillating electric and magnetic fields, which travel at right angles to each other in a bundle of light energy called a photon. ... Magnetic and electric fields of an electromagnetic wave are perpendicular to each other and to the direction of the wave.
They can grow because the fibers in cotton attract and hold water while allowing some free space for air to penetrate. ... Seeds grow not because the cotton has minerals or nutrients required by the plants.
