- 18. Multiple Choice
A population of rabbits grows rapidly from one year to the next. Then one year, a disease strikes approximately one fourth of the adult rabbits. The disease remains with the population in the years that follow.
As explained by Darwin’s theory, which of these conditions allows the rabbit population to evolve by natural selection?
The disease affects adult and juvenile rabbits equally.
The disease reduces the ability of the rabbits to reproduce.
Some rabbits are resistant to the disease, and they pass the resistance to their offspring.
No rabbits are resistant to the disease, and all die when the disease strikes them.
- 19. Multiple Choice
Bactrian camels, dromedaries, llamas, and alpacas are all members of the same taxonomic family, Camelidae. Members of this family all have two toes, no hooves, true canine teeth, and a split upper lip. The family Camelidae originated in North America. The physical features of animals in this family and the family's geographical origin provide evidence that all these animals -
live in the same type of ecosystem
have slowly evolved to become herbivores
have a common ancestor
exchanged DNA at some point in the past
- 20. Multiple Choice
An analysis of DNA and RNA sequences can be used to classify organisms. A dendrogram, such as the one shown below, is based on molecular data. It can be used to represent evolutionary relationships within a group of organisms that are hypothesized to have descended from a common ancestor. Which statement is best supported by the information in this dendrogram?
Lesser pandas are more genetically similar to giant pandas than they are to raccoons
Brown bears are more genetically similar to giant pandas than they are to sun bears
Lesser pandas are more genetically similar to racoons than they are to giant pandas
The bear species are all more genetically similar to dogs than they are to giant pandas
