Why are remotely operated vehicles more effective for researching deep sea regions than using scuba techniques?

• Remotely operated vehicles allow divers more flexibility in colder temperatures.

• Remotely operated vehicles can explore areas that are considered unsafe for humans.

• Scuba technology has become outdated and costly.

• Scuba technology is more effective in freshwater.

Which is the most important reason estuaries make a good nursery for the young of many aquatic species?

• Estuaries are not impacted by tidal pull.

• Estuaries have an endless supply of clean water.

• Estuaries provide adequate food and protection for aquatic young.
