Which process listed does not require oxygen be present? check all answers that apply. a. anaerobic respiration b. aerobic respiration c. ethyl alcohol fermentation d. lactic acid fermentation

Option A, C and D

Explanation:

Anaerobic respiration is carried out in the absence of oxygen by organisms  such as bacteria in extreme geographical conditions  like with in the deep lake , volcanoes etc.

Ethyl alcohol fermentation also known as alcohol fermentation is carried out in the absence of air to produce to carbon dioxide and ethyl alcohol from sugars such as glucose, fructose etc.

Lactic acid fermentation is an anaerobic process in which sugar is converted into lactate. This process takes place in muscle cells after excessive workout or in some anaerobic bacteria.

Thus, option A, C and D are correct.
