37. In studies of two species of barnacles in the marine intertidal zone it was observed that
Chthamalus can live in the upper intertidal zone and the lower intertidal zone if Semibalanus
is absent, and Semibalanus can only live in the lower zone because it is more subject to
dehydration. Based on this, which of the following statements are true? Check all that apply.
