My husband and I *love* to walk ...for hours and hours, and if we decide to go ahead with this potential trip - I'm going to need good shoes. These days, I have some reasonably good shoes for the most part - but they are 2-3 hour walking shoes, not necessarily good for 6+ hours of tromping around.
In cell biology, selective permeability is the property of a living cell membrane that allows the cell to control which molecules can pass through the membrane, moving into or out of the cell.
Best Answer: Selectively permeable is NOT the same as semi-permeable. A piece of dialysis tubing is semi-permeable; some solutes go though depending on their size. A CELL MEMBRANE is selectively permeable because its permeability changes from time to time, depending on the cell's needs.it SELECTS what it is permeable to... piece of dialysis tubing is semi-permeable; some solutes go though depending on their size.
