A researcher performed an experiment to study the growth of two types of bacteria. The bacteria were grown in a broth containing a chemical that reduces the level of
oxygen in the medium. The researcher added the broth to two test tubes. Bacterial species 1 was added to test tube 1, and bacterial species 2 was added to test tube
2. The researcher found that in test tube 1, bacteria gathered at the bottom of the test tube while in test tube 2, bacteria gathered at the top
Item
What can the researcher conclude from the experiment?
Item
Bacteria of species 1 prefer low oxygen conditions and perform anaerobic respiration
Item
O Bacteria of species 1 prefer high oxygen conditions and perform aerobic respiration
Item
O Bacteria of species 2 prefer low oxygen conditions and perform aerobic respiration
Itert
Bacteria of species 2 prefer high oxygen conditions and perform anaerobic respiration
