4. elephant seals from antarctica dive into the ocean more than 1,500 meters deep at a time—nearly a mile. a seal can stay underwater for an hour or longer. to do that, the seal stores oxygen in its blood cells that is slowly released as it dives. the seal does not expend any extra energy releasing the oxygen stored in its blood cells. do you think passive or active transport is at work in the blood cells of the elephant seal? explain your answer.

How does the nervous system affect the excretory system?

How do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.

When sodium chloride dissolves in water the sodium cholride dissociates into?
