a. a plant gall produced by gall flies
b. the waving behavior of fiddler crabs
c. a heterozygote that has one dominant and one recessive allele
d. the open circulatory system in a beetle
7. Drawing on your knowledge of evolution, why is treatment and/or vaccination against viruses particularly
difficult?
a. Their high replication rate increases the probability of beneficial mutations.
b. Their high mutation rate increases the probability of beneficial mutations.

increases the probability of beneficial mutations, and viral reassortment increases the pathogenicity of
viruses.
