Eukaryotic cells of humans and animals possess a selective advantage in the fact that they are capable of both aerobic and anaerobic cellular respiration.
Consider the following statements:
1) Anaerobic respiration allows glycolysis to continue
II) Anaerobic respiration generates more ATP per molecule of glucose
III) Anaerobic respiration regenerates NAD+
IV) Anaerobic respiration prevents the build-up of excess oxygen in the mitochondria
V) Anaerobic respiration results in the removal of a molecule of carbon dioxide per molecule of pyruvate.
Which of the statements best reflects this selective advantage?

A) I and II
B) I and III
C) II and IV
D) I, III, and V
E) II, III, and IV

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.
