Question

while one requires oxygen and one does ____ and anaerobic respiration are both forms of cellular respiration - that is, they are processes by which cells break down glucose to use as energy. which choice completes the text so that it conforms to the conventions of standard english? choose 1 answer: a not. aerobic b not; aerobic c not aerobic d not, aerobic

Explanation:

• The first part of the sentence "While one requires oxygen and one does not" is a complete thought. A comma is needed after "not" to separate it from the next part.
• "Aerobic" is a new term starting a new part of the sentence (describing the other type of respiration), so it should start with a lowercase letter as it's not a proper noun in this context (it's just a type of respiration like "anaerobic" which is lowercase here).

Answer:

D. not, aerobic
