A 45-year-old man inhaled as much air as possible
and then expired with a maximum effort until no more air could be expired. This
produced the maximum expiratory flow-volume curve shown in the following
diagram. What is the forced vital capacity of this man (in liters)?

Meselson and Stahlʹs experiments involved growing E. coli on a medium containing 15N (heavy nitrogen) which increased the density of the bacterial DNA. Cells were then grown on a medium containing only 14N. DNA samples were obtained for analysis after one, two and three rounds of replication (generations) and centrifuged on a density gradient. The double-helical DNA forms bands in the gradient depending on its density. How many bands did Meselson and Stahl see after two generation of cells were grown on the 14N medium?
