The best-adapted organisms are more likely to survive and breed. This is called *

• Mutation

• Natural Selction

• Selective breeding

• Evolution

Broad spectrum antibiotics are good because:

• They Kill many different pathogenic bacteria

• They are really cheap to buy

• They cause antibiotic resistance

• None of the above

Antibiotic resistant bacteria are a problem because:

• It is more difficult to treat people infected with them

• bacteria smell pretty bad

• viruses them grow out of control

• they are not a problem, I love being sick

In small populations, individuals that carry a particular allele may leave more descendants than other individuals, just by chance

• genetic flow

• genetic drift

• genetic trade

• genetic equilibrium

Change in allele frequencies as a result of the migration of a small subgroup of a population

• speciation

• founder effect

• bottleneck effect

the differences in characteristics between organisms

• phenotype

• vestigial structure

• mutation

• variation
