Due to the polarity of _____ , the plasma membrane is selectively permeable: only molecules with certain characteristics are able to pass through the membrane, while others are blocked. A. ions B. Proteins C. Phospholipids D. None of the above
Added by Joseph C.
Step 1
This polarity allows the membrane to be selectively permeable, meaning it can control what substances can pass through it. Ions are charged particles and are generally not able to pass through the nonpolar region of the membrane. Proteins are important Show more…
