The common edible frog of Europe is a hybrid between two species, Rana lessonae and Rana ridibunda. The hybrids were first described in 1758 and have a wide distribution, from France across central Europe to Russia. Both male and female hybrids exist, but when they mate among themselves, they are rarely successful in producing offspring. What can you infer from this information?

The equation for aerobic production of acetic acid from ethanol is ____________

C2H5OH(ethanol) + O2(acetic acid) → CH3CO2H + H2O

Acetobacter aceti bacteria are added to vigorously-aerated medium containing 10 g l^-1 ethanol. After some time, the ethanol concentration is 2 g l^-1 and 7.5 g l^-1 acetic acid is produced. Calculate the Observed yield.
