Mutations are important because they bring about

• death of the organism in which they develop
• genetic variation needed for a population to evolve
• benefits for the individual, not for the population
• Hardey-Weinberg equilibrium within a population

Selective breeding of domesticated plants and animals to produce offspring with desired genetic traits

• Stabilizing selection
• Artificial selection
• Disruptive selection
• Directional selection

Antibiotic resistant strains of bacteria are on the increase, according to data from the CDC. Which of the following best provides a description for antibiotic resistance?

• Sexual reproduction
• Changes in the whole DNA
• Natural selection
• Drug failure

All of the following should be used to construct evolutionary trees EXCEPT 

• DNA sequencing comparison
• morphological similarities and differences
• physical relationsips
• fossil records
