Question
9. Which statement best describes the relationship between the theory of evolution and the origin of life?
O The theory cannot explain the origin of life.
O The theory does not try to explain the origin of life.
O The theory does not contribute understanding to pre-life processes.
O The theory includes an explanation of life's origins.
O 0.63 and 0.37
O 0.37 and 0.63
10. Which of the following would best determine whether two plant species share a recent common ancestor?
O DNA sequences
O Stem lengths
O Flowering times
O Habitat distribution
11. What is genetic variance?
O The magnification of genetic drift as a result of natural events or catastrophes
O The diversity of alleles and genotypes within a population
O The change in a population's genetic structure
O The effect of chance on a population's gene pool
12. How does an adaptation, such as better running speed, relate to natural selection?
O Natural selection randomly mutates individuals' genetic code until it produces beneficial adaptations, such as better running speed.
O Natural selection produces beneficial adaptations, such as better running speed, in individuals that run more frequently.
O Natural selection reproduces individuals with favorable genetic traits, such as the adaptation of better running speed, over time.
O Natural selection produces adaptations, such as better running speed, to help individuals survive and reproduce.
13. Consider a gene with only two alleles: dominant A and recessive a. In a population of 1,000 organisms, the fraction expressing the homozygous recessive phenotype is 0.37. The calculated allele frequencies p and q have values that are closest to
O 0.39 and 0.61
O 0.69 and 0.31
14. If a population stopped reproducing sexually, but still reproduced asexually, how would its genetic variation be affected over time? Could speciation occur in this situation?
O Genetic variation would decrease, and speciation would not be possible.
O Genetic variation would increase, and speciation would not be possible.
O Genetic variation would decrease, and speciation would be possible.
O Genetic variation would increase, and speciation would be possible.
15. What is the ultimate source of all variation in and among populations?
O Genetic mutations that result in viable offspring
O Factors in the environment that may affect development
O Diverse habitats
O Natural selection
