All changes saved Re er krno) Scientists have been studying threats to coral reefs. Some reefs around the Southeast shore of Australia have experienced increased threats while others in the Northwest shore of Australia have seen a decrease in threat. Explain the most effective way that scientists could use this information to design a new study aimed at developing reef protections. (3 points) O Scientists could compare environmental conditions in the threatened Australian reefs with other reefs near Florida, since there would be little overlap in their characteristics. Scientists could compare environmental conditions in the two sets of Australian reefs, because those reefs are more likely to be similar in many ways. This will help highlight the difference that is causing the threat. Scientists could compare environmental conditions in two sets of reefs in Florida and apply that data to the reefs in Australia. Scientists could compare environmental conditions in reefs randomly selected from around the world to get the most variable set of conditions possible and to make good comparisons. (5. (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 characteristic of science does this discovery represent? (3 points) Scientific ideas are not reliable.
