Multiple Choice

In 2010, scientists excavated a skull fossil that provides evidence of a newly discovered species of big cat. Based on the evidence, scientists hypothesize that big cats branched off from smaller wild cats about 6 million years ago. Which of these resources did the scientists most likely rely on to form their hypothesis?

• A food web showing feeding relationships of organisms where the fossil skull was found

• Population and migration data for small wild cats living in the ecosystem where the skull was found

• The fossil record and DNA comparisons of big cats and small cats

• The historical record of interactions between different species of big cats

Multiple Choice

Which is an example of analogous structures?

• bat wing and cat leg

• human arm and whale fin

• butterfly wing and bat wing

• whale fin and cat arm

Multiple Choice

What is an analogous structure?

• having a body part that has no known function

• similar structures in more than one organism because they evolved from a common ancestor

• a structure that evolved to help an organism survive in their environment

• similar structures that evolved independently in two living organisms to serve the same purpose

Multiple Choice

What caused the extinction of the dinosaurs?

• An asteroid hit Earth causing a global climate event.

• A volcanic eruption in Serbia the size of the United States caused CO2 levels to rise creating global warming.

• Abundant plant life removed carbon dioxide (CO2 ) from the air, causing global cooling and glacier formation.

• Human's used an abundance of fossil fuels to emit CO2 gas into the air, causing the temperatures of the globe to rise.
