Answer the following question given this paragraph: The current produced by electromagnetic induction is greater when the magnet or coil moves faster, the coil has more turns, or the magnet is stronger. If the magnet or coil is moved back and forth repeatedly, alternating current is produced. Q: Alternative current is produced when a magnet or coil does what? Choices: - moves in circles at faster rates - moves at faster velocities - moves up and down repeatedly - moves back and forth repeatedly A:
moves back and forth repeatedly
Answer the following question given this paragraph: The ileum is the third part of the small intestine. A few remaining nutrients are absorbed here. Like the jejunum, the inner surface of the ileum is covered with villi that increase the surface area for absorption. Q: The site of some nutrient absorption, the ileum is the third part of what digestive organ? Choices: - stomach - large intestine - rectum - small intestine A:
small intestine
Q: Answer the following question given this paragraph: Most chromosomal disorders involve the sex chromosomes. Can you guess why? The X and Y chromosomes are very different in size. The X is much larger than the Y. This difference in size creates problems. It increases the chances that the two chromosomes will fail to separate properly during meiosis. Q: Most chromosomal disorders involve which chromosomes? Choices: - autosomes - ribosomes - protosomes - sex chromosomes A:
A: sex chromosomes
Question: Answer the following question given this paragraph: Figure 20.33 The outer surface of the heart changes from positive to negative during depolarization. This wave of depolarization is spreading from the top of the heart and is represented by a vector pointing in the direction of the wave. This vector is a voltage (potential difference) vector. Three electrodes, labeled RA, LA, and LL, are placed on the patient. Each pair (called leads I, II, and III) measures a component of the depolarization vector and is graphed in an ECG. Q: The outer surface of the heart changes from positive to negative during what? Choices: - inflammation - permeability - reproduction - depolarization A:
Answer: depolarization

Answer the following question given this paragraph: Humans have been making and using magnifying lenses for thousands of years. The term "telescope" was coined by the Italian scientist and mathematician Galileo Galilei (15641642). Galileo built the first telescope in 1608. His telescope used two lenses to make distant objects appear both nearer and larger. He subsequently made many improvements to telescope design. Q: Which scientist built the first telescope? Choices: - einstein - newton - darwin - galileo A:
**Answer**
galileo
Q: Answer the following question given this paragraph: A lava plateau is made of a large amount of fluid lava. The lava flows over a large area and cools. This creates a large, flat surface of igneous rock. Lava plateaus may be huge. The Columbia Plateau covers over 161,000 square kilometers (63,000 square miles). It makes up parts of the states of Washington, Oregon, and Idaho. Q: When lava flows over a large area and cools, it creates a large, flat surface of what type of rock? Choices: - tidal - sedimentary - metamorphic - igneous A:
A: igneous
