Answer:
Makali may produce only small amounts of a non-mutated (wild-type) GALT enzyme.
Makali may have normal amounts of GALT, but the enzyme may be mutated.
Explanation:
Makali is lactose intolerant because of his ancestry. Because of this he is not able to digest any lactose which indirectly protected him from galactosemia. Thus he must avoid consuming galactose. He has a low GALT or galactose 1‑phosphate uridylyltransferase activity. He has a normal amount of GALT and may produce only small amounts.
The pyloric sphincter is compose of smooth muscle and is located between the pylorus in the stomach and duodenum of the small intestine. In digestion, it serves as a valve controlling the flow of food thus it prevents the contents of small intestine backing up into the stomach.
