Answer the following question given this paragraph: Long Bones A long bone is one that is cylindrical in shape, being longer than it is wide. Keep in mind, however, that the term describes the shape of a bone, not its size. Long bones are found in the arms (humerus, ulna, radius) and legs (femur, tibia, fibula), as well as in the fingers (metacarpals, phalanges) and toes (metatarsals, phalanges). Long bones function as levers; they move when muscles contract. Q: What type of function does the long bone perform? Choices: - acts as pivot - works as piston - acts as pulley - work as lever A:
work as lever

Ques: Answer the following question given this paragraph: Cardiac muscle undergoes aerobic respiration patterns, primarily metabolizing lipids and carbohydrates. Myoglobin, lipids, and glycogen are all stored within the cytoplasm. Cardiac muscle cells undergo twitch-type contractions with long refractory periods followed by brief relaxation periods. The relaxation is essential so the heart can fill with blood for the next cycle. The refractory period is very long to prevent the possibility of tetany, a condition in which muscle remains involuntarily contracted. In the heart, tetany is not compatible with life, since it would prevent the heart from pumping blood. Q: What kind of muscle cells undergo twitch-type contractions with long refractory periods followed by brief relaxation periods, allowing the heart to fill with blood for the next cycle? Choices: - nervous muscle - skeletal muscle - smooth muscle - cardiac muscle A:
Ans: cardiac muscle

Ques:Answer the following question given this paragraph: Scientists don't know for certain why magnetic reversals occur, but there is hard evidence that they have for hundreds of millions of years. The evidence comes from rocks on the ocean floor. Look at Figure below . They show the same ridge on the ocean floor during different periods of time. Q: Where does evidence that magnetic reversals occur come from? Choices: - snow - Volcanoes - air - rocks on ocean floor A:

Ans:rocks on ocean floor
Question: Answer the following question given this paragraph: Scientists study meteorites to learn about Earth's interior. Meteorites formed in the early solar system. These objects represent early solar system materials. Some meteorites are made of iron and nickel. They are thought to be very similar to Earth's core ( Figure below ). An iron meteorite is the closest thing to a sample of the core that scientists can hold in their hands!. Q: Some meteorites are made of iron and nickel and are thought to be very similar to what part of the earth? Choices: - crust - shelf - mantel - core A:
Answer:
core
