One of the following is true not about chain and step growth polymerization. Group of answer choices A. Unsaturated monomers undergo chain growth polymerization whereas monomers with two more functionality undergo step polymerization. B. The molecular weight of the mer and the monomer are the same in both polymerization methods. C. In chain growth polymerization very large molecular weight polymer can be produced very quickly whereas in step growth polymerization large molecular weight polymer is formed when nearly all monomers are consumed. D. An initiator is needed for chain polymerization but nor for step polymerization. E. All are correct.

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.
