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: The stratosphere contains a layer of ozone gas. Ozone consists of three oxygen atoms (O 3 ). The ozone layer absorbs high-energy UV radiation. As you can see in Figure below , UV radiation splits the ozone molecule. The split creates an oxygen molecule (O 2 ) and an oxygen atom (O). This split releases heat that warms the stratosphere. By absorbing UV radiation, ozone also protects Earth's surface. UV radiation would harm living things without the ozone layer. Q: What is the name for the stratospheric gas layer that protects living things from uv radiation? Choices: - carbon layer - atmospheric layer - toposphere - ozone layer A:
ozone layer

Answer the following question given this paragraph: Q: What is a measure of how hot or cold the air is? Choices: - precipitation - variation - relativity - temperature A:
temperature

Answer the following question given this paragraph: The chemical reaction that is the opposite of oxidation is called reduction. Following from the notion that oxidation was originally thought to mean only the addition of oxygen, reduction was thought to be only the removal of oxygen from a substance. Many naturally occurring metal ores are present as oxides. The pure metals can be extracted by reduction. Iron is obtained from iron(III) oxide by reacting with carbon at high temperatures. Q: What chemical reaction is the opposite of oxidation? Choices: - mutation - condensation - evaporation - reduction A:
reduction
