How does the simple primary and secondary structure of dna hold the information needed to code for the many features of multicellular organisms?
the base sequence of dna carries all the information needed to code for proteins.
the hydrogen bonding among backbone constituents carries coded information.
the amino acids that make up the dna molecule contain the information needed to make cellular proteins.
the width of the double helix changes at each gene due to differences in hydrogen bonds.

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.
