Escherichia coli is characterized as a facultative anaerobe. You set up an experiment to examine the growth of E. coli in 3 environments: a gasPak jar(0% oxygen), a candle jar(10% oxygen), and the benchtop(22% oxygen). Aside from differing oxygen levels, all other culture conditions (such as temperature and media used) were kept constant. Which of the following represents the most likely outcome of the experiment?
E. Coli will have heavy growth on the benchtop but moderate growth in the candle jar and the GasPak jar.

d.

explanation:

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
