74-75. SHORT ANSWER (answer in space below) CHOOSE 1
A. Why is it easier to swim in a sea or ocean than a lake?
B. Why are the Indonesian area coral reefs particularly diverse?
A. We are more buoyant (able to float) in salt water because the density of the water is
closer to that of our density.
B. It is an intersection (transitional zone) between two oceans (Pacific & Indian).
Transitional zones are more diverse.
