Why is water sometimes called the "universal solvent"?
Because water dissolves all solutes equally well.
Because water is a nonpolar solvent.
Because water is good at dissolving ions and polar molecules.
Because water is poor at dissolving nonpolar molecules.
The Correct Answer is C
Water is sometimes called the “universal solvent” because it dissolves more substances than any other liquid.
This is due to its polarity and ability to form hydrogen bonds, which allows it to dissolve ions and polar molecules.
Choice A) Because water dissolves all solutes equally well is incorrect because water does not dissolve all solutes equally well.
Choice B) Because water is a nonpolar solvent is incorrect because water is a polar solvent.
Choice D) Because water is poor at dissolving nonpolar molecules is incorrect because it does not explain why water is called the “universal solvent”.

Correct Answer is B
Explanation
The proximal tubule is responsible for reabsorbing all the nutrients and most of the water.
Choice A is incorrect because the distal tubule is not primarily responsible for reabsorbing ions, water and nutrients.
Choice C is incorrect because the glomerulus is responsible for filtering fluid and solutes out of the blood to form a glomerular filtrate.
Choice D is incorrect because the Loop of Henle is not primarily responsible for reabsorbing ions, water and nutrients.
Correct Answer is B
Explanation
Osmosis is the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.
The concentration of solute particles in the solution is the primary factor that determines the movement of water across cell membranes in osmosis.
Hydrostatic pressure (choice A) can affect the movement of water across cell membranes but is not the primary factor responsible for osmosis.
Temperature (choice C) can affect the rate of osmosis but is not the primary factor responsible for osmosis.
Kinetic energy of liquid water molecules (choice D) can affect the rate of osmosis but is not the primary factor responsible for osmosis.
