Q: Which disease causes cells to divide out of control Read this paragraph and choose the correct option from the provided answers: Cancer is a disease that causes cells to divide out of control. Normally, the body has systems that prevent cells from dividing out of control. But in the case of cancer, these systems fail. Cancer is usually caused by mutations. Mutations are random errors in genes. Mutations that lead to cancer usually happen to genes that control the cell cycle. Because of the mutations, abnormal cells divide uncontrollably. This often leads to the development of a tumor. A tumor is a mass of abnormal tissue. As a tumor grows, it may harm normal tissues around it. Anything that can cause cancer is called a carcinogen . Carcinogens may be pathogens, chemicals, or radiation. Choices: - autoimmune diseases - mutation - arthritis - cancer A:
cancer

Q: What do glands in the skin produce to cool down the body? Read this paragraph and choose the correct option from the provided answers: glands in the skin that produce sweat, a salty fluid that helps cool down the body. Choices: - lactic acid - saliva - mucus - sweat A:
sweat

Q: Q: The great astronomer edwin hubble discovered that all distant galaxies are receding from our milky way galaxy with velocities proportional to their what? Read this paragraph and choose the correct option from the provided answers: (a) A jet airplane flying from Darwin, Australia, has an air speed of 260 m/s in a direction 5.0 south of west. It is in the jet stream, which is blowing at 35.0 m/s in a direction 15 south of east. What is the velocity of the airplane relative to the Earth? (b) Discuss whether your answers are consistent with your expectations for the effect of the wind on the plane's path. (a) In what direction would the ship in Exercise 3.57 have to travel in order to have a velocity straight north relative to the Earth, assuming its speed relative to the water remains 7.00 m/s ? (b) What would its speed be relative to the Earth? 60. (a) Another airplane is flying in a jet stream that is blowing at 45.0 m/s in a direction 20 south of east (as in Exercise 3.58). Its direction of motion relative to the Earth is 45.0 south of west, while its direction of travel relative to the air is 5.00 south of west. What is the airplane's speed relative to the air mass? (b) What is the airplane's speed relative to the Earth? 61. A sandal is dropped from the top of a 15.0-m-high mast on a ship moving at 1.75 m/s due south. Calculate the velocity of the sandal when it hits the deck of the ship: (a) relative to the ship and (b) relative to a stationary observer on shore. (c) Discuss how the answers give a consistent result for the position at which the sandal hits the deck. The velocity of the wind relative to the water is crucial to sailboats. Suppose a sailboat is in an ocean current that has a velocity of 2.20 m/s in a direction 30.0 east of north relative to the Earth. It encounters a wind that has a velocity of 4.50 m/s in a direction of 50.0 south of west relative to the Earth. What is the velocity of the wind relative to the water? 63. The great astronomer Edwin Hubble discovered that all distant galaxies are receding from our Milky Way Galaxy with velocities proportional to their distances. It appears to an observer on the Earth that we are at the center of an expanding universe. Figure 3.64 illustrates this for five galaxies... Choices: - masses - paths - dimensions - distances A:
A: distances

Question: Q: Some flatworms are free-living carnivores that live mainly in which type of habitats? Read this paragraph and choose the correct option from the provided answers: Many flatworms are parasites with vertebrate hosts. Some are free-living carnivores that live mainly in aquatic habitats. Choices: - Deciduous forest - Desert - freshwater - aquatic A:
Answer: aquatic

Q: In which state does matter need to be for nuclear fusion? Read this paragraph and choose the correct option from the provided answers: Unfortunately, using energy from nuclear fusion is far from a reality. Scientists are a long way from developing the necessary technology. One problem is raising temperatures high enough for fusion to take place. Another problem is that matter this hot exists only in the plasma state. There are no known materials that can contain plasma, although a magnet might be able to do it. That's because plasma consists of ions and responds to magnetism. You can learn more about research on nuclear fusion at the URL below. Choices: - cells state - solid state - gaseous state - plasma state A:
**Answer**
plasma state

(Q).
Q: What is the process of processing used material into new ones called? Read this paragraph and choose the correct option from the provided answers: Now we move on to recycle. Sometimes it may be difficult to understand the differences between reusing and recycling. Recycling involves processing used materials in order to make them suitable for other uses. That usually means taking a used item, breaking it down, and reusing the pieces. Even though recycling requires extra energy, it does often make use of items which are broken, worn out, or cannot be reused. Choices: - remake - renew - reuse - recycling A:
(A).
recycling
