The respiratory system is responsible for taking in oxygen and releasing carbon dioxide. When a person walks, he or she breathes at a fairly slow rate. However, when he or she starts running, the oxygen reguirement of the body increases, and the body is
signaled to increase the rate at which the person breathes, Which body system interacts with the respiratory system to signal that the
body's oxygen reguirement has changed?

How do temperature and salinity affect deepwater currents? 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.
