Why cell membrane is called selectively permeable membrane?

Explanation:

The plasma membrane is called a selectively permeable membrane b/c it permits the movement of only certain molecules in and out of the cells. It allows hydrophobic molecules and small polar molecules diffuse through the lipid layer, but does not allow ions and large polar molecules cannot diffuse through the membrane.

Remember selectively means; in a way that  involves the selection of only particular people or things.

the framers of the constitution insisted that federal judges be nominated instead of elected due to their desire to have judges above the shifting whims of the masses.

the hope, whether achieved or not, was that federal judges would only be beholden to the law and that by not having judges be elected, they would be protected if that law dictated an outcome that ran counter to popular opinion.
