Q: Answer the following question given this paragraph: Water erosion by runoff, rivers, and streams dissolves carbon in rocks and carries it to the ocean. Ocean water near the surface dissolves carbon dioxide from the atmosphere. Dissolved carbon may be stored in the deep ocean for thousands of years. Q: How many years can dissolved carbon be stored in the deep ocean? A:
Answer: thousands

Problem:OPTIONS:
- oxygen and dioxide
- phosphorus and oxygen
- dioxide and nitrogen
- nitrogen and oxygen

Answer the following question given this paragraph: Figure below shows the main gases in air. Nitrogen and oxygen make up 99 percent of air. Argon and carbon dioxide make up much of the rest. These percentages are the same just about everywhere in the atmosphere. Q: What makes up 99 percent of air? A:
****
A: nitrogen and oxygen

Answer the following question given this paragraph: An estuary is a partly enclosed coastal body of water with one or more rivers or streams flowing into it, and with a free connection to the ocean. Estuaries can be thought of as the most biologically productive regions on Earth, with very high biodiversity. Estuaries are zones where land and sea come together, and where fresh and salt water meet. Q: What can be thought of as the most biologically productive regions on earth? A:
OPTIONS:
- swamps
- forests
- coasts
- estuaries
estuaries

Question: Answer the following question given this paragraph: The aim of basic science is to discover new knowledge. It leads to a better understanding of the natural world. It doesn't necessarily have any practical use. An example of basic research in life science is studying how yeast cells grow and divide. Yeasts are single-celled organisms that are easy to study. By studying yeast cells, life scientists discovered the series of events called the cell cycle. The cell cycle works not only in yeasts but in all other organisms with similar cells. Therefore, this basic research made a major contribution to our understanding of living things. Watch the following animation to learn more about the basic yeast research and the cell cycle. You can also see yeast cells dividing. Q: What kind of organisms are yeasts? A:
OPTIONS:
- bacteria
- viruses
- protozoa
- single-celled
Answer: single-celled

input: OPTIONS:
- epipelagic
- observable zone
- mesopelagic
- aphotic zone Now, answer this question: Answer the following question given this paragraph: Below 200 meters is the aphotic zone. There are no primary producers here because there isn't enough sunlight for photosynthesis. However, the water may be rich in nutrients because of dead organisms drifting down from above. Organisms that live here may include bacteria, sponges, sea anemones, worms, sea stars, and fish. Q: Which zone is located below 200 meters from the surface? A:
A:
output:
aphotic zone
