Insect wings and bird wings serve a similar function but are structurally different. This is an example of...

• homologous structures

• analagous structures

• vestigial structures

• disruptive selection

many animals have humerus, radius, and ulna bones because their common ancestor had those bones. This is an example of...

• homologous structures

• analogous structures

• vestigial structures

• disruptive selection

Which seed is best adapted for long-distance wind dispersal?

• milkweed

• maple

• burdock

• none of them

Which of these flower adaptations would be most successful for the survival of a species?

• spiny seeds for better wind dispersal

• different flowering times for better seed dispersal

• sticky pollen for better water dispersal

• specific odors for better insect pollination

Adaptive radiation is best described as...

• unrelated organisms developing similar structures due to similar environmental pressures

• when organisms change via habitual use and disuse of certain traits

• multiple species evolving from one common ancestor

• populations that are isolated from one another develop different traits

Which is an example of natural selection?

• Selective breeding of tail-less cats

• Giraffes stretching their necks to reach higher leaves

• Juvenile birds learning to sing

• Dark colored moths being less predated in dark colored forests

Leopard frogs and Green frogs have very distinct calls, which prevents interbreeding. This is an example of...

• pre-zygotic reproductive barrier

• post-zygotic reproductive barrier

• natural selection

• competition

Lions and Tigers can produce hybrid offspring called Ligers, however Ligers are infertile and cannot produce offspring of their own. This is an example of...

• Pre-Zygotic Reproductive Barrier

• Post-Zygotic Reproductive Barrier

• Natural Selection

• Competition

A group of lizards migrates across a landbridge from mainland to an island. The landbridge is eventually covered by water. What might we expect to happen as a result of this isolation?

• The island population may diverge and develop new traits in response to their environment

• The two populations will remain the same

• The island population will find a way to get back to the mainland

• The island population will diverge genetically, but not anatomically

Which best defines the principle of biogeography?

• the study of different biomes

• the study of migration patterns of animals

• the distribution of different biomes across the globe

• the distribution of life forms over geographical areas
