Question: A genetic mutation prevents the parietal cells of the gastric glands from secreting their typical products. What effect would this have on digestion within the stomach?
Answer Choices: A. The stomach would not produce a protective mucus coating and would digest itself.; B. Somatostatin would be secreted, so all digestion would be halted.; C.
