Which characteristics describe deep ocean currents? check all that apply.

have lower-salinity water
carry cold water to the poles
have higher-temperature water
move more slowly than surface currents
caused by differences in water density

the answers are 2,4,5 or b,d,e

Explanation:

just took the test

Option (2), (4) and (5)

Explanation:

The deep ocean current is very cold and have a very low temperature. They have high salinity and high density and moves at a much slower rate compared to the surface current.

As this current moves, it carries the cold water with them from the equatorial region to the poles. The thermohaline circulation is formed which is a portion of the global ocean water circulation, and is generated due to the differences in water density between the upper oceanic water body and the lower portion of the water body.

Thus, the correct answers are options (2), (4) and (5).

they may bind directly to special “promoter” regions of dna, which lie upstream of the coding region in a gene, or directly to the rna polymerase molecule.
