Practice EOC/Final Exam Review

Front

What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring. It is a key mechanism of evolution.

Front

What are homologous structures?

Back

Homologous structures are body parts in different species that have a similar structure but may serve different functions, indicating a common ancestor.

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the number of different species, genetic diversity, and ecosystem diversity.

Front

What is carrying capacity?

Back

Carrying capacity is the maximum number of individuals of a particular species that an environment can support sustainably.

Front

What are vestigial structures?

Back

Vestigial structures are body parts that have lost their original function through evolution, such as the human appendix.

Front

What is genetic drift?

Back

Genetic drift is a mechanism of evolution that refers to random changes in the frequency of alleles in a population, which can lead to significant changes over time.

Front

What is the significance of the fossil record?

Back

The fossil record provides evidence of the history of life on Earth, showing how species have changed over time and supporting the theory of evolution.

Front

What is taxonomy?

Back

Taxonomy is the science of classifying organisms into groups based on shared characteristics and evolutionary relationships.

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with their physical environment, including both biotic and abiotic factors.

Front

What is a common ancestor?

Back

A common ancestor is an ancestral species from which two or more different species have evolved.
