Answer:
When the cell excretes sodium from within against the natural tendency of matter it is performing active transport.
Answer: Solar energy heats the equator consistently throughout the year. The colder poles receive less solar energy due to Earth's curvature and axial tilt. The equator temperature averages above 64°F all year. The north pole ranges from 32°F to −40°F and the south pole annually varies from −18°F to −76°F.

Answer:
Ocean desalination, Using nuclear fusion as an energy source and using stem cell technology to cure disease.
Explanation:
Ocean desalination is the major problem that occurs due to removing of nutrients that is present in the ocean water because of human activities. These nutrients are essential for the marine animals so for solving this problem, we should use other alternative energy resources in order to reduce ocean desalination. Using nuclear fusion as an energy source is a good idea but it can't be implemented on the earth because it requires 100 million degrees Celsius which is impossible to generate. Using stem cell technology to cure disease is a great idea which can cure many diseases in the human body. This available technology is used by replacing damaged cells with the healthy cells.
A delta is formed when a high flow water body meets a low flow one. Meaning, when a river meets a lake or ocean. The river carries sediment because of it's high energy (flow). When it suddenly slows down the sediment drops out all at once and a delta forms.
