Natural Selection

A grizzly bear survives because he is well-adapted to his environment. When he reproduces he passes on those traits to his offspring. this process is called

• Natural Selection

• Selective Breeding

• Random mutations

• Variations in a species

The peppered moth's color camouflaged it on the light colored tree bark. It's color was an example of a/n

• Variation

• Dominant trait

• Recessive trait

• predation

If a sick person takes an antibiotic but it doesn't kill all of the bacteria causing the sickness, what might explain this?

• Variations in the bacteria allowed some organisms to be less affected by the antibiotic?

• Bacteria cannot be killed by antibiotics

• You cannot cure a bacterial infection

• Bacteria do not cause sicknesses

The male and female black widow spider look very different. However, we know they are the same species because:

• They reproduce creating fertile offspring

• They reproduce creating infertile offspring

• They cannot reproduce

• They are not the same species

Genetic drift is change in the allele frequency of a population due to...

• random chance
• natural selection
• non-random mating (sexual selection)
• artificial selection

 Genetic Drift is more likely to happen in... 

• aquatic populations
• small populations
• terrestrial populations
• older populations

The type of genetic drift that follows the colonization of a new habitat by a small group of individuals is called

• the Hardy-Weinberg principle
• the founder effect
• directional selection
• the bottleneck effect

What is this an example of?

• homologous structures

• variation

• vestigial structures

• DNA studies

Behavioral changes of individuals of a species that allow for better survival. (Acquired traits)

• Variation
• Adaptation
• Behavior
• Environment
