1 Bonsai trees, like the one to the right, have been nurtured over many generations by Japanese gardeners. a. The adjustments made to the phenotypes of the trees are not heritable* c.

The shape and size of the plants represents the result of artificial selection.
2 The figure to the right describes the evolution of drug resistance in HIV where the drug is a reverse transcriptase inhibitor. Notice that all three colored lines begin on the left axis at a point above 0% of HIV resistant to 3TC. What is the significance of the observation that the number is greater than zero? a. apparently prior to the appearance of HIV in human populations, some humans had a characteristic that preadapted them to survive upon exposure to the virus. b. in a population of HIV viral particles, a small proportion are of a genetic type that they are not effected by the drug.* c. as soon as the human population became exposed to HIV, some individuals adapted to the situation d. that is probably just a sampling error e. upon exposure to the drug, some viral particles adapt by mutation to a form that can thrive in the face of the drug. 3 The authors of our textbook describe a study in Chapter 1 that investigated the relationship between warningly colored and venomous coral snakes and their non-venomous kingsnake mimics. David Phennig, a former UTSA student, and his coworkers put artificial snakes, some looking like coral snakes and others with a uniformly brown coloration, on the ground at 14 field sites. Seven of the sites were frequented by coral snakes (“Coral Snakes...
