The cells lining the proximal convoluted tubule Group of answer choices reabsorb organic nutrients, plasma proteins, and ions from the tubular fluid. are unusually tall, and their nuclei are clustered together. reabsorb water and reabsorb or secrete sodium, potassium, hydrogen, and bicarbonate ions. are closely associated with unusual smooth muscle fibers. are not permeable to water and solutes.

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.
