This question is 4 marks. 1) osmosis is the net movement of water 2) from an area of high concentration to an area of low concentration 3) across a partially permeable membrane 4) importance: allows cells...

First work out the area of the triangular face using the formula 1/2 A B sin c:1/2 x 1.4 x 1.4 sin(34) = 0.548m²
recall volume of a regular prism = area of face x length
hence V = 0.5...
