Q: Answer the following question given this paragraph: The troposphere is the lowest layer of the atmosphere. In it, temperature decreases with altitude. The troposphere gets some of its heat directly from the Sun. Most, however, comes from Earth's surface. The surface is heated by the Sun and some of that heat radiates back into the air. This makes the temperature higher near the surface than at higher altitudes. Q: What do we call the lowest layer of the atmosphere? A:

OPTIONS:
- stratosphere
- asthenosphere
- mesosphere
- troposphere

A: troposphere

****
A: reverse transcription

Problem:OPTIONS:
- spontaneous mutation
- variation
- generation
- evolution

Answer the following question given this paragraph: Evolution is a change in the characteristics of living things over time. Evolution occurs by a process called natural selection. In natural selection, some living things produce more offspring than others, so they pass more genes to the next generation than others do. Over many generations, this can lead to major changes in the characteristics of living things. Evolution explains how living things are changing today and how modern living things have descended from ancient life forms that no longer exist on Earth. Q: The change in the characteristics of living things over time is known as _________ A:
****
A:
