Question 1

How would you classify the genetic basis for most behavioral traits in the animal kingdom?

Accepted Answer

Most behavioral traits are complex and are influenced by many genes working together, rather than a single gene. Therefore, many genes typically code for one behavior. Additionally, environmental factors and learning also play a role in shaping behaviors.

Question 2

-From the figure above,what can we determine about the location of the food source?

Accepted Answer

The waggle dance in the bottom figure indicates that the food is 90 degrees to the right of the Sun.

Question 3

What is the lizard's bobbing dewlap (a colorful flap of skin hanging from an Anolis lizard's throat)is an example of?

Accepted Answer

The lizard's bobbing dewlap is a signal because it is a visible cue that the lizard is sending to other lizards, either as a warning or as a display of dominance.

Question 4

Scientists believe that the direction birds go when migrating is guided in part by
I.the stars in the night sky.
II.the Sun during the day.
III.the magnetic field of the Earth.

Accepted Answer

Scientists believe that the direction birds go when migrating is guided by a combination of factors including the stars in the night sky, the Sun during the day, and the magnetic field of the Earth. Birds have specialized receptors in their eyes that allow them to see the Earth's magnetic field, which helps them navigate. They also use the position of the Sun and stars to orient themselves. Therefore, all three options (I, II, and III) are correct.

Question 5

Which of the following experiments best addresses the hypothesis that moths stop flying in response to high-intensity bat sounds?

Accepted Answer

The experiment in choice B directly tests the hypothesis by exposing moths to high-intensity bat sounds and observing their response. The other options are not directly related to the hypothesis.

Question 6

You observe a species of bird that,upon hatching,has contact with its parents only while being fed.You also never hear the parents sing during the feeding process.What would you propose about song learning in this species of bird?

Accepted Answer

The observation that the parents never sing during the feeding process suggests that the bird's song is not being learned from the parents, which makes it more likely that song learning in this species is innate.

Question 7

Which of the following has a coefficient of relatedness of 0.25?

Accepted Answer

An uncle to his nephew has a coefficient of relatedness of 0.25, as they share one-quarter of their genes.

Question 8

If a prairie dog had the opportunity to perform an altruistic act (that is,give an alarm call)to help its relatives,which combination of the following relatives would the prairie dog be most likely to help (base your answer solely on the genetic relationships)?

Accepted Answer

The answer of If a prairie dog had the opportunity...

Question 9

When does learning have the most influence on behavior?

Accepted Answer

When making mistakes does not result in death, learning has the most influence on behavior as animals are able to experiment and make errors without fatal consequences. This allows for more opportunities for learning and behavioral adaptation.

Question 10

Which of the following statements supports the idea that behaviors are important in survival and therefore affect natural selection?

Accepted Answer

Innate behaviors, which are genetically determined, have been selected for over generations because they increase individual survival and reproductive success. This supports the idea that behaviors are important in survival and affect natural selection.

Question 11

-What was the main reason the honeybees switched from the "round dance" to the "waggle dance"?

Accepted Answer

The waggle dance was developed as a way for honeybees to communicate the location of a food source that was farther away than the sources previously communicated through the round dance.
