Question

In one paragraph, describe the research methods used in this study and why you believe they were chosen. Be sure to use key terms such as cross-sectional research, longitudinal research, data collection, observation, case studies, questionnaires, and experimentation, as they apply. Your answer should include at least two of these key terms.

Answer 1

I think experimentation and observation. I think this because when you study things you always want to observe the behaviors of the subject closely. Once you have got the details of the subject you need to experiment with it. You should repeat the experiment to make sure your answers are accurate.

Answer 2

Answer:The first method is biological restoration in which scientists try to increase the reproduction rate of the corals. The techniques vary depending on the reef. For example, an overgrowth of algae was affecting the growth of coral reefs in one area. So, scientists focused on controlling the algal growth. This method is less invasive than transplanting entire

reefs into the ocean. However, it only works in areas where coral reefs are still healthy enough to bounce back from the damage. Another group of scientists took samples of corals' genomes to find out whether there are types of corals that are more likely to survive warmer temperatures. This method may allow scientists to plant heat resistant corals in high-risk areas. The drawback is the high cost and the time required for genetic testing.
