PLEASE HELP! I REALLY NEED THIS! Positive transcription factor (PTR) is important because it turns genes on to prepare them to be read. What is more important (i. e., which has a greater impact if it is changed): concentration or affinity?

If PTR concentration is low but affinity is high, then what will happen to protein levels versus if PTR affinity is high but concentration is low?

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.
