because Ganglia were the evolutionary precursor to the centralized concentration of neurons that we now call a brain.
Answer:
The missing options are:
a. "It's due to insufficient production of vitamin B12 in the colon."
b. "Increased production of intrinsic factor in the stomach leads to this type of anemia."
c. "Overproduction of vitamin B12 in the large intestine can result in pernicious anemia."
d. "Decreased production of intrinsic factor by the stomach affects the absorption of vitamin B12 in the small intestine."
The correct answer is d. "Decreased production of intrinsic factor by the stomach affects the absorption of vitamin B12 in the small intestine."
Explanation:
Intrinsic factor is a protein that is produced by cells in the stomach, this protein is essential for the absorption of vitamin B12 in the small intestine. Without intrinsic factor, the absorption of vitamin B12 would be really low, causing pernicious anemia since vitamin B12 is necessary for the production of healthy red blood cells. If there is not a good production of healthy red blood cells that can distribute O₂ and CO₂, the body suffers from pernicious anemia.
