Answer:
Something studied on the molecular level is the water.
Explanation:
Water is a molecule formed by two hydrogen atoms and one oxygen atom, whose chemical representation is H₂O. It is a molecule whose polarity makes it a universal solvent of other polar molecules.
The molecular level corresponds to the level of organization where two or more atoms unite to form molecules or substances, united by chemical bonds. H₂O is studied at this level due to its chemical structure.
With respect to other options:
- <u><em>Hydrogen and oxygen</em></u><em> are atoms, and correspond to the level of atomic organization.</em>
- <u><em>Protons</em></u><em> are particles that are part of an atom, and correspond to the subatomic level.</em>

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.
The seven major plates<span> are the African </span>plate<span>, Antarctic </span>plate<span>, Eurasian </span>plate<span>, Indo-Australian </span>plate<span>, North American </span>plate<span>, Pacific </span>plate<span>and South American </span><span>plate</span>
All of these are body regions.
Antecubital, brachial, crural, and femoral regions are ventral/anterior appendicular body regions.
Axillary region is ventral/anterior axial body region.
Popliteal and sural body regions are dorsal/posterior appendicular body regions.
