The acacia ants provide the acacia plant with protection against other potentially damaging insects, as well as other plants which may compete
for nutrients and sunlight, in return, the plant provides the ants with
shelter and essential nutrients for the ants and their growing larvae. What
pattern of evolution does this describe?

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.
