Hat types of skeletal changes occurred during whale evolution? What change (or transition) in habitat did whales’ ancestors make? Which fossil organism in whale evolution do you think was the first to live mostly in water? Explain your claim with evidence and reasoning. Explain the changes in the skeletons during the transition in habitat according to the theory of natural selection. What are the similarities and differences between the whale fossils? How does fossil evidence determine the relationships of whale ancestors and their descendants?

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.
