(01.01 LC) Up until 1938, paleontologists accepted the idea that coelacanths (an ancient fish) went extinct at the time that they last appear in the fossil record, about 80 million years ago. But in 1938, a live coelacanth was discovered off the coast of South Africa. What goal of science does this discovery represent? (3 points)

(01.04 MC) The Earth is a unique planet in that it is covered by more than 70 percent water. There are several properties of water that make Earth a suitable environment for life, including how the density of solid water (ice) is about nine percent less than the density of liquid water. Which best explains why this feature of water is important for marine life? (3 points)
