[FW.04H]The graph below shows the trends in water use in the United States from 1950 to 2000.

Based on the graph, a student would most likely conclude that, from 1950 to 2000, the total amount of water used for irrigation is approximately

half of the total water withdrawn
one-fifths of the total water withdrawn
one-sixths of the total water withdrawn
two-fifths of the total water withdrawn

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.

i think the miocene epoch spans the time from 23 million to 12 million years ago.

hope this : )
