The first multicellular animal to evolve were invertebrates. Why have so few fossils of these organisms been found? A. Their soft bodies do not fossilize well.

B. There were very few species alive long ago.

C. High rates of predation forced many to extinction before they could be preserved.

D. Conditions were not right for preservation at the time when they lived.

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.
