Question

All living things need to transport molecules from one place to another in order to carry out necessary life functions.

Living things often transport these molecules by dissolving or dissociating them in water and then moving the
resulting solution from place to place. What two properties of water allow it to perform the functions mentioned
above?
A. polarity and good solvent
C. good solvent and high specific heat
B. polarity and high heat of vaporization D. density and polarity

Answer 1

The correct answer is Option A. polarity and good solvent.

Explanation:

Polarity is the property of water molecules to make poles. Poles are formed between two atoms having difference in electronegativity values. In water molecules, partial positive charge appears on hydrogen atom and partial negative charge appears on oxygen atom. Water is universal solvent which means it dissolves maximum number of solutes within itself.
