Form a Hypothesis A scientist uses radioactive nitrogen to label the nitrogenous bases
of the DNA of a cell. Then the DNA is allowed to replicate, and the new strands take up
non-radioactive bases. Do one, both, or neither of the daughter cells have radioactive
DNA? Explain.

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.
