Answer 1

Answer:

b) earth worm

Explanation:

According to Elmer, many blood substitutes have failed in the past because they've relied on a process of extracting hemoglobin from red blood cells and putting it back into the bloodstream. Earthworms, however, don't have red blood cells. Elmer believes that's what makes the critters an ideal source for hemoglobin.
