Regarding the tonicity and osmolarity of solutions,which of the following statements is not true?
A)The term "tonicity" refers to the effect that a solution has on the degree of stretch or shrinking of the cell membrane.
B)The term "osmolarity" refers to the osmotic properties of a solution,regardless of its tonicity.
C)Isotonic solutions are always isoosmotic.
D)Hypoosmotic solutions are always hypotonic.
E)Hypertonic solutions are always hyperosmotic.
