Questions and Answers

Why did Satomi choose fish, frogs, turtles, lizards, snakes, crocodiles, and chickens to investigate the question of which came first, the chicken or the egg?

They all have similarities in their embryological development. (correct)
They all have eyes that are adapted to their environment.
They all use oxygen as a primary means of respiration.
They all use unique methods of locomotion.

Based on the cladogram, what is the evolutionary relationship between chickens and frogs?

Chickens and frogs are closely related because neither have scales.
Chickens and frogs share a common ancestor. (correct)
Chickens evolved legs from frogs.
Chickens' social behavior of living in groups evolved from frogs.

On the cladogram, the shelled egg likely first appeared in organisms after the split between frogs and ______.

turtles

Provide an explanation for why organisms below where the egg was placed on the cladogram in Part A produce soft, unshelled eggs?

The organisms that branched out below that point in the cladogram are both aquatic animals. Those animals lay unshelled eggs because they lay their eggs in the water and don't have to worry about the eggs drying out. Signup and view all the answers

As the outdoor temperature increases throughout the day, what happens to the air molecules in the tire?

The air molecules gain thermal energy and move farther apart from one another. (C) Signup and view all the answers

Move descriptions to the appropriate column in the chart to explain what happens to the air inside the tire vs. in the atmosphere when the temperature increases:

Inside the Tire = Pressure increases. In the Atmosphere = Pressure decreases Signup and view all the answers

Based on the conditions both inside and outside the tire, explain why the bicycle tire popped.

The air temperature increased throughout the day. This made the air particles inside the tire move faster and faster. Because the tire has a fixed volume, the increased movement of the heated air particles resulted in rapidly increasing pressure inside the tire. The materials that make up the tire can only withstand so much maximum pressure, and as the pressure inside the tire became too great, it reached a point where it popped.

What can Leo do differently next time to prevent his tire from popping? (Select the two most likely options.)

What can Veronica best infer about the two identified rock layers in the Grand Canyon and Zion National Park?

Veronica examines rock layer G4 and rock layer Z4. What can Veronica best infer about the two rock layers?

Rock layer G4 is older than rock layer Z4 because G4 is below a common rock layer found in both locations. (D) Signup and view all the answers

Veronica examines relationships between the three parks by using the diagram to compare the rock layers in each. Which inference can she make about the relationship between the three parks?

The rock layers of Zion National Park are the link in the geologic timeline between the Grand Canyon and Bryce Canyon National Park because there are rock layers common to all three parks. (B) Signup and view all the answers
