3. the graph, pictured right,
illustrates the temperature
changes at willis island in the
coral sea from 1939-2001. the
researchers proposed the
hypothesis:
at willis island in the coral sea, coral
bleaching occurred from 1953-1966.
a. discuss whether the data
represented in the graph
supports this hypothesis.
4. outline an experiment that researchers could do to test whether corals on a reef are currently bleaching.
your answer should include reference to the control of variables and the collection of quantitative results.

What is the difference between the conducting zone and the respiratory zone of the respiratory system? the conducting zone is a series of cavities and tubes that move air to the respiratory zone where gases exchange with the bloodstream. the conducting zone exchanges gases between the lungs and the alveoli and the respiratory zone is a series of cavities and tubes that move air to the conducting zone. the conducting zone moves oxygen into the cells and the respiratory zone takes carbon dioxide away from the cells. the conducting zone moves oxygen into the bloodstream and the respiratory zone takes carbon dioxide away from the bloodstream.
