which choice completes the text so that it conforms to the conventions of standard english?
choose 1 answer:
not. aerobic
not; aerobic

Explanation:

• A period is used to end the first independent clause ("While one requires oxygen and one does not").
• "Aerobic" (starting with a capital letter) is correct as it is the start of a new sentence (the second independent clause).
