In recent years, commercial beekeepers have reported colony collapse: the disappearance of entire colonies of bees. A biologist, Dr. B, argues that colony collapse is caused by a new parasite, to which bees have not acquired immunity. A chemist, Dr. C, argues that colony collapse is caused by genetic damage from pesticides. And an ecologist, Dr. E, argues that 3 specific commercial beekeeping practices—transportation of hives over long distances, indiscriminate medication, and inbreeding—compromise both the immunity and the genetic diversity of bees, leaving them susceptible to mass die-offs from normally benign microbes.
Complete the table based on the stated views of Dr. B, Dr. C, and Dr. E. In the first column, select the factor common to both Dr. B’s and Dr. E’s accounts of colony collapse. In the second column, select the factor common to both Dr. C’s and Dr. E’s accounts of colony collapse. Make two selections, one in each column.
