Honors Biology Exam 5

Front

What is an Analogous Structure?

Back

Structures that have similar functions but different evolutionary origins, indicating convergent evolution.

Front

What is a Homologous Structure?

Back

Structures that have the same parts but different functions, suggesting a common ancestry among organisms.

Front

What is a Vestigial Organ?

Back

A structure that has lost most or all of its original function through the course of evolution.

Front

What is Stabilizing Selection?

Back

A type of natural selection that favors average individuals in a population.

Front

What is Directional Selection?

Back

A type of natural selection that favors one extreme phenotype over the others.

Front

What is Disruptive Selection?

Back

A type of natural selection that favors extreme phenotypes at both ends of the spectrum.

Front

What is Adaptive Radiation?

Back

The process by which organisms diversify rapidly into a wide variety of forms to adapt to different environments.

Front

What is Natural Selection?

Back

The process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is the significance of Fossils in Biology?

Back

Fossils provide evidence of past life and evolutionary changes over time.

Front

What is the difference between Convergent and Divergent Evolution?

Back

Convergent evolution occurs when unrelated species evolve similar traits, while divergent evolution occurs when related species evolve different traits.
