Q: Evolution (Unit 8)

The gradual change in species over time is...

• Evolution
• 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 

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

• Variation
• Adaptation
• Behavior
• Environment

Remains of ancient organisms are called

• Extinctions
• Fossils
• Mutations
• Variations

A group of similar organisms that can mate with each other and produce fertile offspring is called a species.  

• True  
• False

The measure of the frequency of an allele at a genetic locus in a population; expressed as a proportion of percentage.

• Allele Frequency

• Embryology

• Evolution

• Extinction

The branch of zoology studying the early development of living things.

• Allele Frequency

• Embryology

• Evolution

• Extinction

A decrease in genetic variation caused by the formation of a new population by a small number of individuals from a larger population.

• Fossils

• Founder Effect

• Gradualsim

• Isolating Mechanisms
