Build a simple fire extinguisher model that can work at home using recycled materials. the appliance must be able to extinguish the fire caused by gas and oil just describe how it works.

The small molecule cyclic amp (camp) takes about 0.2 second to diffuse 10 μm, on average, in a cell. suppose that camp is produced near the plasma membrane on one end of the cell; how long will it take for this camp to diffuse through the cytosol and reach the opposite end of a very large cell, on average? assume that the cell is 200 μm in diameter.
