The CA biotype thrives on a diet rich in raffinose, while the MA biotype prefers sucrose. The host transfer experiment tests how these biotypes adapt to new diets and the effects on their sugar metabolism. The goal is to determine which statement about their metabolic responses is incorrect, with the answer indicating that the CA biotype did not adapt well to a sucrose-only diet after transfer."}
