Answer to Question 1

The demographic stability of Europe and most of Latin America means that the Catholic Church will probably grow more in Sub-Saharan Africa than in any other world region.

Answer to Question 2

Some cyanobacteria have heterocysts, which are separate cells that fix N2, but do not produce O2. Nitrogenase, the enzyme used to fix N2, is poisoned by O2, and heterocysts allow N2 to be fixed by this enzyme for the benefit of the O2-producing cyanobacteria.
