Answer the following question given this paragraph: Most nonmetals are poor conductors of heat. In fact, they are such poor conductors of heat that they are often used for insulation. For example, the down filling in this sleeping bag is full of air, which consists primarily of the nonmetal gases oxygen and nitrogen. These gases prevent body heat from escaping to the cold outside air. Q: What are the three most common elements in the air we breathe? Choices: - oxygen, nitrogen, H20 - nitrogen, argon, hydrogen - argon, oxygen, hydrogen - nitrogen, oxygen and argon A:
nitrogen, oxygen and argon
Answer the following question given this paragraph: The rod-shaped organisms in Figure below are bacteria called Salmonella . Bacteria (bacterium, singular) are prokaryotes in the Bacteria Domain. The word Salmonella may sound familiar. That's because Salmonella is a common cause of food poisoning. Many other types of bacteria also cause human diseases. But not all bacteria are harmful to people. In fact, we could not survive without many of the trillions of bacteria that live in or on the human body. You'll learn why when you read this lesson. Q: Bacteria are what kind of cell? Choices: - protists - blood - eukaryotes - prokaryotes A:
prokaryotes
Q: Answer the following question given this paragraph: In the winter, the temperature often gets well below the freezing point of water. This condition can create problem in car radiators. If the water freezes, water hoses will break, the engine block can crack, and significant damage can be done to the car. Q: In winter, water does what, becoming solid and causing hoses to rupture and engine blocks to crack? Choices: - crystallizes - shrinks - fractures - freeze A:
A: freeze

Answer: bladder

Answer the following question given this paragraph: An underwater earthquake creates a tsunami this way: The movement of the crust displaces water. The displacement forms a set of waves. The waves travel at jet speed through the ocean. Since the waves have low amplitudes and long wavelengths, they are unnoticed in deep water. As the waves reach shore they compress. They are also pushed upward by the shore. For these reasons, tsunami can grow to enormous wave heights. Tsunami waves can cause tremendous destruction and loss of life. Fortunately, few undersea earthquakes generate tsunami. Q: What type of amplitudes and wavelengths avoid detection in deep water? Choices: - high and long - high and wide - low and wide - low and long A:
**Answer**
low and long
Answer the following question given this paragraph: Introduction Plants have evolved different reproductive strategies for the continuation of their species. Some plants reproduce sexually, and others asexually, in contrast to animal species, which rely almost exclusively on sexual reproduction. Plant sexual reproduction usually depends on pollinating agents, while asexual reproduction is independent of these agents. Flowers are often the showiest or most strongly scented part of plants. With their bright colors, fragrances, and interesting shapes and sizes, flowers attract insects, birds, and animals to serve their pollination needs. Other plants pollinate via wind or water; still others self-pollinate. Q: Unlike plants, animal species rely almost exclusively on what type of reproduction? Choices: - pollination - multiplication - regeneration - sexual reproduction A:
sexual reproduction
