Heavy DNA ( N15N15 DNA), hybrid DNA, and light DNA ( N14N14 DNA) can be separated by centrifugation. If cells containing N15N15 DNA are transferred to a medium with only N14N14 NH4ClNH4Cl as a nitrogen source, what percent of daughter molecules are composed of hybrid DNA after 33 generations

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.
