61.病毒题
变体评价 Lyme disease is caused by a bacterium transmitted to humans by deer ticks.Generally, deer ticks pick up the bacterium while in the larval stage by feeding on infected white-footed mice.However, certain other species on which the larvae feed do not harbor the bacterium.If the population of these other species were increased, more of the larvae would be feeding on uninfected hosts, so the number of ticks acquiring the bacterium would likely decline.
【正解】B. Whether the size of the deer tick population is currently limited by the availability of animals for the tick's larval stage to feed on
