The gradual change in species over time is...

• Nucleotide 
• Adaptation
• Natural Selection

Darwin wrote that organisms with traits that are best suited to the environment will ________________

• increase in number
  
• become extinct
  

Which term refers to the process by which individuals that are better suited to the environment survive and reproduce therefore passing down their genes to their offspring? 

• Evolution 
• Variation 
• Adaptation
• Natural Selection 

When an organism completely dies out, it is called.....

• Adaption
• Extinction
• Fossilization
• Mutation

The white feathers of a snowy owl allow it to blend in with its environment during the winter months (snow). This is an example of ________________

• Species
• Environmental Change
• Adaptation
• Variation

Genetic differences between organisms of the same species

• Adaptation
• Behavior
• Environment

• To look different from other species.
• To be able to eat the food readily available in the environment.
• To protect itself against predators.
• To protect itself against prey.

The struggle for existence against other members of an organisms species is

• Competition
• Natural Selection
• gene flow
• genetic drift

Remains of ancient organisms are called

• Fossils
• Mutations
• Variations
