Answer:

Step-by-step explanation:

1. A. Increases in the population of sea creatures

- Increases in the population of sea creatures can indicate a sign of recovery after an oil spill. As the ecosystem begins to recover, the population of sea creatures may start to rebound.

2. C. 20-50 percent

- Illegal fishing is thought to account for approximately 20-50 percent of fish caught. This represents a significant portion of the overall fishing industry.

3. B. Leaking oil tankers

- Leaking oil tankers put the most oil into ocean waters. These accidents can result in large quantities of oil being released directly into the ocean.

4. B. False

- Oil spills can be devastating for sea life on the ocean floor. The oil can smother and contaminate the organisms living there, causing long-term damage to the ecosystem.

5. D. Remain in the environment for a long time

- A very persistent pollutant would remain in the environment for a long time. This means that it does not easily break down or degrade naturally.

6. A. It creates air pollution.

- Burning oil creates air pollution, releasing harmful pollutants into the atmosphere. This can have negative impacts on human health and the environment.

7. B. Currents

- Currents make trash more likely to end up in some areas of the ocean. They can transport debris, including trash, to certain regions and concentrate it there.

8. A. True

- Motorboats can wound or kill creatures in the ocean. The propellers and hulls of motorboats can pose a threat to marine life, particularly to animals near the water surface.

9. C. To provide a food source in some areas

- Asian carp were introduced in the United States to provide a food source in some areas. However, they have become an invasive species and pose ecological challenges.

10. C. Mercury

- Mercury is a toxin that bioaccumulates. This means that it accumulates and increases in concentration as it moves up the food chain, potentially causing harm to organisms at higher trophic levels.

11. B. Tourist businesses

- Environmental laws focus on protecting marine habitats, endangered species, and non-renewable resources. They do not specifically target tourist businesses.

12. B. To minimize pollution in waterways

- The goal of the Clean Water Act is to minimize pollution in waterways. It establishes regulations and standards to ensure the protection and restoration of water quality.

13. A. True

- The Food and Drug Administration (FDA) is one of the agencies that monitor the quality of seafood. They have regulations and guidelines in place to ensure the safety of seafood products.

14. D. 87 days

- It took 87 days to stop the flow of oil from the Deepwater Horizon incident. This was a significant and prolonged oil spill that required extensive efforts to contain and stop the flow.

15. B. False

- The great pacific garbage patch does not look like a huge island of trash when seen from the air. It is primarily composed of small pieces of plastic debris dispersed over a large area, making it less visible from above.
