Answer the following question given this paragraph: Specialized structures for reproduction: One example is a fruiting body. Just like a fruit is involved in the reproduction of a fruiting plant, a fruiting body is involved in the reproduction of a fungus. A mushroom is a fruiting body , which is the part of the fungus that produces spores ( Figure below ). The spores are the basic reproductive units of fungi. The mycelium remains hidden until it develops one or more fruiting bodies. Q: Spores are the basic reproductive units of what organism? Choices: - mushrooms - yeast - tropical plants - fungi A:
fungi
Answer the following question given this paragraph: Q: What part of a plant, which is attached to its stem nodes, is the "main organ" of photosynthesis? Choices: - flowers - roots - spores - leaves A:
leaves
Q: Answer the following question given this paragraph: How high or low a sound seems to a listener is its pitch . Pitch, in turn, depends on the frequency of sound waves. Wave frequency is the number of waves that pass a fixed point in a given amount of time. High-pitched sounds, like the sounds of the piccolo in the Figure below , have high-frequency waves. Low-pitched sounds, like the sounds of the tuba Figure below , have low-frequency waves. For a video demonstration of frequency and pitch, go to this URL: http://www. youtube. com/watch?v=irqfGYD2UKw. Q: Dependent on the frequency of sound waves, what term described how high or low a sound seems to a listener? Choices: - curve - wavelength - direction - pitch A:
A: pitch
Question: Answer the following question given this paragraph: Four underlying principles form the basis of biology. They are cell theory, gene theory, homeostasis, and evolution. Q: How many underlying principles does the science of biology have? Choices: - five - three - eleven - four A:
Answer: four

Answer the following question given this paragraph: The process in which a solid changes directly to a gas is called sublimation . It occurs when the particles of a solid absorb enough energy to completely overcome the force of attraction between them. Dry ice (solid carbon dioxide, CO 2 ) is an example of a solid that undergoes sublimation. Figure below shows a chunk of dry ice changing directly to carbon dioxide gas. Sometimes snow undergoes sublimation as well. This is most likely to occur on sunny winter days when the air is very dry. What gas does snow become?. Q: What is the process in which a solid changes directly to a gas called? Choices: - condensation - solidification - vaporization - sublimation A:
(A).
sublimation
