| Platelet membranes bear a higher density of receptors per surface area than any other blood cell. |
| By such thickening, mesophyll surface area per leaf area becomes greater in sun leaves than in shade leaves. |
| The young people want a hard surface area with kerbstones or similar for skateboarding. |
| To make matters worse, fish have large respiratory membranes, the gills, which expose a huge amount of surface area to the watery medium. |
| The folding increases junctional surface area by 10 to 20 times, decreasing the stress per unit area. |
| One of the reasons why this is more likely to happen when lapping flip chips is the small surface area. |
