Which of the following is considered a behavioral adaptation?

• Dogs barking in response to an unidentified noise.
• Long trunks of elephants 
• Birds wings that allow them to fly
• They white underbelly of a shark

You look at two species and see very similar DNA. What does this likely tell you?

• These are the same animal.
• These animals have a common ancestor.
• These animals are not likely related.
• These animals are likely becoming one species.

Squirrel populations are different colors throughout the United States. Squirrels in the southeast are red while squirrels in the northwest are typically gray. What accounts for this color difference?

• Chemicals in the clay cause mutations in the squirrels causing them to turn red.
• Red squirrels migrated to warmer climates because they didn't like the cold weather of the north.
• Red squirrels are red because it is warmer in the south.
• Red squirrels have adapted to the environment in the southeast because of the red color of the soil.

What do the homologous structures of human and wolf bones tell us?

• We both use our bones for the same things, leading to similar structures.
• They had a common ancestor.
• Humans are descendants of wolves.
• It is impossible to tell.

What causes a species to evolve over time?

• Extinctions
• Chromosome recombinations and mutations
• The cycle of the moon
• Extinctions and environmental changes.

What does sexual reproduction allow for?

• Increased genetic diversity
• Increased offspring
• Decreased genetic diversity
• Decreased rate of evolution

Antibiotics are frequently given to humans that have strep throat. Why might this practice be considered a problem?

• Antibiotics cause mutations which could change to something deadly.
• The human body can metabolize the antibiotic to quickly, not allowing the antibiotic to reach the bacteria.
• A mutation can occur in the bacteria making it resistant to the antibiotic.
• Nothing will happen. It takes thousands of years for bacteria to evolve and become antibiotic resistant.
