Another passive process is osmosis. This is the process by which water crosses a cell membrane either into or out of the cell, but always into the solution that has the higher total concentration of solutes. Dr Aziz.
The flying buttress is the defining external characteristic of gothic architecture. These buttresses act to spread the weight of the tall walls. They support the structure by transferring force directly to the ground. The flying buttress was not just practical, though.
Three architectural features are typical of the Gothic. These are the pointed arch, the ribbed vault, and the flying buttress. It is the pointed arch that most clearly makes Gothic building look different from Roman and Romanesque work. In the older style the semicircular, round arch was used everywhere.But Gothic architects did not invent the pointed arch. It had been used much earlier in the Near East.ne of the most important styles of European art that developed during the Middle Ages was called Romanesque. This style began during the 1000's and lasted for more than 200 years. Romanesque architecture is massive, low, and solid-looking. Round Roman arches, thick walls, and small windows are typical of the buildings.
