Question: Answer the following question given this paragraph: Along with the skin, the integumentary system includes the nails and hair. Both the nails and hair contain the tough protein, keratin. The keratin forms fibers, which makes your nails and hair tough and strong. Keratin is similar in toughness to chitin, the carbohydrate found in the exoskeleton of arthropods. Q: What is the name of the protein that is found in hairs and nails? A:
OPTIONS:
- cellulose
- chromatin
- Skin
- keratin
Answer: keratin

Notice the sperm with the head piece containing the genetic material, a flagella tail that propels the sperm, and a midpiece of mostly mitochondria, supplying ATP. Q: What part of the sperm contains the genetic material? A:
OPTIONS:
- the " body "
- the " tail "
- the " brain "
- the "head"
output: the "head"

While matter cycles round and round in the Earth System, ENERGY FLOWS through the Earth System. The vast majority of Earth's energy comes from the sun, flows into the Earth's System, and flows out of the Earth's System into space. If all the energy that comes to Earth from the sun were to stay on Earth, the Earth would melt away. But the energy that comes to Earth from the sun does not stay. Eventually it radiates back out to space as heat. We know this because the average temperature of the Earth has remained relatively constant. If the energy from the sun were to stay on Earth, the Earth's average temperature would rise. Some of the sun's energy is reflected by the atmosphere, some is absorbed by the Earth and re-radiated as heat, some evaporates water and powers the water cycle, some is captured by plants and used to make sugars, and some powers the wind but eventually ALL of the energy that comes to the Earth from the sun leaves the Earth and flows into space. For this reason we say that energy flows through the Earth System. Q: Where does most of the earth's energy come from? A:
A:
output: sun

Answer the following question given this paragraph: Migration Migration is the long-range seasonal movement of animals. It is an evolved, adapted response to variation in resource availability, and it is a common phenomenon found in all major groups of animals. Birds fly south for the winter to get to warmer climates with sufficient food, and salmon migrate to their spawning grounds. The popular 2005 documentary March of the Penguins followed the 62-mile migration of emperor penguins through Antarctica to bring food back to their breeding site and to their young. Wildebeests (Figure 45.35) migrate over 1800 miles each year in search of new grasslands. Q: What evolved, adapted response to resource availability is the long-range seasonal movement of animals? A:

OPTIONS:
- changing
- Stagnation
- regulating
- migration

Answer: migration
