Biology SOL Review #4

Front

What is the main cause of speciation?

Back

Isolation is the primary cause of speciation, as it prevents gene flow between populations, leading to the development of distinct species.

Front

Who proposed the theory of Survival of the Fittest and Evolution?

Back

Charles Darwin proposed the theory of Survival of the Fittest and the concept of evolution through natural selection.

Front

What is the common ancestor of species C and D?

Back

The common ancestor of species C and D is represented by number 4 in the phylogenetic tree.

Front

Who is the closest relative to the brown bear?

Back

The closest relative to the brown bear is the sun bear.

Front

What method uses radioactive elements to determine the actual age of fossils?

Back

Absolute Dating uses radioactive elements to determine the actual age of fossils.

Front

Define speciation.

Back

Speciation is the evolutionary process by which populations evolve to become distinct species.

Front

What is natural selection?

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

Explain the concept of adaptation in biology.

Back

Adaptation refers to the process by which a species becomes better suited to its environment through evolutionary changes.

Front

What is the difference between relative dating and absolute dating?

Back

Relative dating determines the age of fossils based on their position in layers of rock, while absolute dating provides a specific age using radioactive elements.

Front

What role does isolation play in evolution?

Back

Isolation can lead to speciation by preventing gene flow between populations, allowing them to evolve independently.
