If the formation of nanotubes is genetically and energetically less expensive than some
biosynthetic pathways, two independent species of compatible, nanotube-forming bacteria
could evolve to do what?
Choose one:
OA. lose different, complementary biosynthetic pathways and become
dependent on each other
B. lose the same biosynthetic pathways and become dependent on each
other
O C. constitutively express biosynthetic enzymes and become dependent
on each other
OD. constitutively express biosynthetic enzymes to compete with each
other
