Natural Selection

Where the better adapted organisms survive to pass traits along to offspring.

• Evolution
• Natural Selection
• Extinction
• Artifical Selection

Mutations are a change in what?

• DNA
• tRNA
• genotype
• phenotype

What word describes a trait that helps an organism survive in its environment?

• natural selection

• mutation

• camouflage

• adaptation

Which organisms are most likely to survive?

• the best adapted
• the fastest
• the strongest
• the most domesticated (tamed)

The trees these moths used to live on were white, but have been covered in soot from coal factories. Which moth will be more successful in this environment?

• Dark moth
• Light moth
• Both will be equally successful
• Neither will be successful

Change over time

• Natural Selection
• Selective Breeding
• Homeostasis
• Evolution

Why is the mouse population changing over time?

• The light mice can reproduce more successfully than the dark mice
• The hawks eat more dark mice than light mice because the dark mice taste better
• The hawks eat more light mice than dark mice because they can see the light mice more easily
• The hawks eat more dark mice than light mice because they can see the dark mice more easily

These moths are all the same species. The differences between their wings is an example of ________________

• Natural Selection
• Variation
• Homeostasis
• Extinction

A slight difference in an inherited trait between individual members of the same species.

• variations
• adapatations
• homologous structures
• analogous structures

An inherited trait that increases an organism's chance of surviving and reproducing.

• variation
• adaptation
• vestigial structure
• mutation
