Answer the following question given this paragraph: The supertree also shows that another major diversification of mammals occurred about 50 million years ago. Again, worldwide climate change may have been one reason. This time Earth's temperature rose. The warmer temperature led to a greater diversity of plants. This would have meant more food for mammals or their prey. Q: A major diversification of what animal group occurred about 50 million years ago, possibly spurred by worldwide climate change? Choices: - reptiles - amphibians - insects - mammals A:
mammals
Answer the following question given this paragraph: According to the Aufbau process, sublevels and orbitals are filled with electrons in order of increasing energy. Since the s sublevel consists of just one orbital, the second electron simply pairs up with the first electron as in helium. The next element is lithium and necessitates the use of the next available sublevel, the 2 s . Q: According to which process, sublevels and orbitals are filled with electrons in order of increasing energy? Choices: - Schrodinger's cat - hausen - particle dynamics - aufbau A:
aufbau
Q: Answer the following question given this paragraph: Eventually a main sequence star will use up all of its hydrogen. It then starts to fuse helium atoms into larger elements like carbon. At this time, the star's core will collapse inward. The star's outer layers will spread out and cool. The result is a larger star that is cooler on the surface, and red in color. The star is now a red giant . Q: When a star's core collapses inward while the outer layers spread and cool, what "colorful" celestial body forms? Choices: - blue giant - green giant - white giant - red giant A:
A: red giant
