5b. When a tick sucks in a blood meal that contains Lyme disease bacteria, at first these bacteria live in the tick’s gut where the bacteria get nutrition from the blood meal. When the tick begins its next blood meal, the Lyme disease bacteria move from the tick's gut to its salivary glands. Why is this ability to move to the salivary glands a needed adaptation for Lyme disease bacteria? What would happen to any Lyme disease bacteria that were unable to move from the tick's gut to its salivary glands?
