When a lineage splits into multiple line of descents, then, it leads to speciation. It is a process by which a single population evolves into different species.  The process of speciation leads to the development of two or more species as  the lineages are splitted. These two evolved species are genetically independent.
Hence, the blank can be filled with 'speciation'.

Answer:
30 minutes
Explanation:
Bacteria reproduce by binary fission, a process by which one parent cell divides to form 2 progeny cells. Because one cell produces 2 progeny cells, bacteria are said to undergo exponential ( logarithmic) growth.
As in the case of staphylococcus aureus, we start with 100 cells ,  and after 90 minutes number becomes 800 that means  , firstly the cells doubled (100 x 2 = 200 ) after 30 minutes. Again after 30 minutes they doubled ( 200 x 2 =400 ) and again after 30 minutes they doubled (400 x 2 = 800). So in 90 minutes 100 cells became 800 cells.
Hence the generation time for S.aureus is 30 minutes.
