Question

since the cell membrane allows some molecules to pass through it and will not allow others, it can be described as multiple choice completely pervious. impervious. selectively permeable. permeable. impermeable.

Explanation:

The cell membrane's property of allowing some molecules to pass and blocking others is known as selective permeability. A completely pervious membrane would allow all molecules through, an impervious or impermeable membrane would allow none, and a simply permeable membrane doesn't convey the selective nature.

Answer:

C. selectively permeable
