What is meant by the following statement? The cell membrane is semipermeable. A. The membrane allows all polar molecules into the cell. B. The membrane is very specific about what it allows to pass through. C. The membrane does not contain any membrane proteins. D. The membrane will not allow any molecules to pass through.
I believe the correct answer would be B. Semipermeable means that it allows certain substances to pass through, and certain other ones to not pass through. So given all of your options, I would say that B makes the most sense. Hope this helped!
