Answer the following question given this paragraph: Preserved traces can include footprints, burrows, or even wastes. Examples of these types of fossils, called trace fossils are picture below ( Figure below and Figure below ). Q: Footprints, burrows, and waste are considered what type of fossils? Choices: - movement fossils - crater fossils - morphology fossils - trace fossils A:
trace fossils
Answer the following question given this paragraph: If water is so simple, why is it special? Water is one of the few substances that exists on Earth in all three states of matter. Water occurs as a gas, a liquid and a solid. You drink liquid water and use it to shower. You breathe gaseous water vapor in the air. You may go ice skating on a pond covered with solid water ice in the winter. Q: In how many states does water exist on earth? Choices: - one matter states - eight matter states - two matter states - three matter states A:
three matter states
Q: Answer the following question given this paragraph: Flammability is the ability of matter to burn. Wood is flammable; iron is not. When wood burns, it changes to ashes, carbon dioxide, water vapor, and other gases. After burning, it is no longer wood. Q: The ability of matter to burn is called? Choices: - solubility - eccentricity - unpredictability - flammability A:
A: flammability
Question: Answer the following question given this paragraph: Q: What is vital for nervous system functions that include muscle stimulation, memory formation, and learning? Choices: - thiamine - glutamate - glycogen - acetylcholine A:
Answer: acetylcholine

Answer the following question given this paragraph: 46.3 | Biogeochemical Cycles By the end of this section, you will be able to: Discuss the biogeochemical cycles of water, carbon, nitrogen, phosphorus, and sulfur Explain how human activities have impacted these cycles and the potential consequences for Earth Energy flows directionally through ecosystems, entering as sunlight (or inorganic molecules for chemoautotrophs) and leaving as heat during the many transfers between trophic levels. However, the matter that makes up living organisms is conserved and recycled. The six most common elements associated with organic moleculescarbon, nitrogen, hydrogen, oxygen, phosphorus, and sulfurtake a variety of chemical forms and may exist for long periods in the atmosphere, on land, in water, or beneath the Earth's surface. Geologic processes, such as weathering, erosion, water drainage, and the subduction of the continental plates, all play a role in this recycling of materials. Because geology and chemistry have major roles in the study of this process, the recycling of inorganic matter between living organisms and their environment is called a biogeochemical cycle. Water contains hydrogen and oxygen, which is essential to all living processes. The hydrosphere is the area of the Earth where water movement and storage occurs: as liquid water on the surface and beneath the surface or frozen (rivers, lakes, oceans, groundwater, polar ice caps, and glaciers), and as water vapor in the atmosphere. Carbon is found in all organic macromolecules and is an important constituent of fossil fuels. Nitrogen is a major component of our nucleic acids and proteins and is critical to human agriculture. Phosphorus, a major component of nucleic acid (along with nitrogen), is one of the main ingredients in artificial fertilizers used in agriculture and their associated environmental impacts on our surface. Q: What do we call the recycling of inorganic matter between living organisms and their environment? Choices: - phosphorus cycle - nutrient cycle - water cycle - biogeochemical cycle A:
**Answer**
biogeochemical cycle
Answer the following question given this paragraph: Weather makes life interesting. Weather also causes weathering. Weathering is the slow wearing down of rocks on Earth's surface. Wind-blown sand scours rocks like sandpaper. Glaciers of ice scrape across rock surfaces like a file. Even gentle rain may seep into rocks and slowly dissolve them. If the water freezes, it expands. This eventually causes the rocks to crack. Without the atmosphere, none of this weathering would happen. Rocks at the surface would be pristine and unaltered. Q: What is the term for the slow wearing down of rocks on earth's surface? Choices: - slipping - evaporation - experiencing - weathering A:
weathering
