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.
The Plasma Membrane is a selectively permeable membrane as it only allows entry and exit of some selected molecules into and out of the Cells. It also prevents movement of s â¦ ome other materials, therefore the plasma membrane is called a selectively permeable membrane. 104 people found this useful. Johnellishartford.
