Front

What are body fossils?

Back

Body fossils are the preserved remains of ancient organisms, such as bones and teeth.

Front

What are trace fossils?

Back

Trace fossils are geological records of biological activity, such as footprints or burrows made by ancient animals.

Front

What is coevolution?

Back

Coevolution is the process where two or more species influence each other's evolution, often seen in interactions like pollination.

Front

What are alleles?

Back

Front

What is the significance of fossils in understanding prehistoric life?

Back

Fossils provide valuable information about the anatomy, behavior, and environment of ancient organisms.

Front

What is an example of a trace fossil?

Back

Footprints left by dinosaurs are an example of a trace fossil.

Front

What can cause variations in traits among organisms?

Back

Variations in traits can be caused by different alleles present in the gene pool.

Front

What is the role of bumblebees in coevolution with flowers?

Back

Bumblebees pollinate flowers while feeding on nectar, influencing the evolution of both species.
