Survival of the Fittest
for $400
Darwin's studies of finches on the Galapagos
Islands suggest that the finches' differences in
beak structure were most directly due to

finches
( B.)the size of the island where the finches live
( C.)mating behaviors of the different finch
species
( D.)adaptations of the finches to different
environments

Survival of the Fittest
for $500
Certain strains of bacteria that could be killed by
penicillin have now become resistant and penicillin is
no longer effective. The probable explanation for this
is that
a.the gene mutation rate must have increased naturally.
b.the strains have become resistant because they needed
to do so for survival.
c.a mutation that gave some of them resistance was
passed on to succeeding generations because it had
high survival value.
d.the penicillin influence the bacterial pattern of mating.
Answer
c.a mutation that gave some of them
resistance was passed on to succeeding
generations because it had high
survival value.
