Read the steps below about how a reflex occurs. Which step does not belong? Sense receptors react to something, such as touching something hot. A nerve ending is stimulated and sends a signal up a nerve. The signal enters the spinal cord through a dorsal connection. The signal is sent to the brain and interpreted. A message is sent to the muscles. The muscles are stimulated and move in response.

How do temperature and salinity affect deepwater currents? 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. 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 density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water.
