During the inventory of bacterial genes present in the Sargasso Sea, a deep isolated area in the middle of the Atlantic Ocean, a research team concluded that at least 1,800 bacterial species were present. Based on what you might predict about the habitat structure of such an area, what kind of bacterial diversity would you expect to see in tropical coral reef waters?

Which of the following statements about the C4 cycle is true ?
a.) C4 plants uses the enzyme phosphoenolpyruvate carboxylase (PEPCase), rather than rubisco
b.) Unlike rubisco, O2 does not compete with HCO3 − in the carboxylation catalyzed by PEPCase
c.) initial carboxylation catalyzes in bundle sheath cells, four-carbon acids formed and flow across the diffusion barrier to the mesophyll cells
d.) during decarboxylation, releasing CO2 that is refixed by rubisco via the Calvin–Benson cycle
