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 ________________

• Environmental Change
• Adaptation
• Variation

Darwin referred to this as survival of the fittest. Over time, it results in changes in the inherited characteristics of a population because organisms with adaptations that make them fit for their environment will survive and reproduce better than those without favorable traits.

• Natural Selection
• Genetic Variation
• Survival of the Fittest

What is the advantage of having different shaped beaks?

• 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.

Some organisms have genes that improve their ability to survive and reproduce. If the gene also help their offspring survive and reproduce, then which of the following will most likely increase?

• The number of genes in a species
• The frequency of genes in a population
• The frequency of genes in one individual

The opossum and kangaroo both incubate their young in a pouch. This provides evidence that they---

• are descended from a common ancestor
• Have very similar skeletal structures
• belong to the same species
• must range great distances to eat

The concept of gene flow is demonstrated when a cow is driven off from its herd, joins another herd, and reproduces. When the cow contributes to the gene pool of the new herd, which of these will most likely increase?

• Environmental fitness
• Reproductive mutations
• Natural selection
• Genetic variation

The table shows the survival rate of two types of beetles in the same environment over a period of three years.  

Which statement about the beetles in this environment is best supported by the data?

• Brown beetles have a shorter life cycle than green beetles have
• Green beetles are more fit for their environment than brown beetles
•  brown beetles are undergo more unfavorable mutations than green beetles

The similarities of the bones in the diagram provide evidence that---

• The organisms shown lived in the same natural envionrment
• The organisms shown may have developed from a common ancestor
• The organisms shown have the same genetic diseases
• All vertebrate species have identical forelimbs
