passage: Calcium channel blocker toxicity is the taking of too much of the medications known as calcium channel blockers (CCBs) either by accident or on purpose. This often causes a slow heart rate and low blood pressure. This can progress to the heart stopping altogether. Some CCBs can also cause a fast heart rate as a result of the low blood pressure. Other symptoms may include nausea, vomiting, sleepiness, and shortness of breath. Symptoms usually occur in the first six hours but with some forms of the medication may not start until 24 after hours.
 question: do calcium channel blockers cause shortness of breath?
Yes

passage: Africanized bees have spread across the southern United States, where they pose a slight danger to humans (making beekeeping--particularly hobby beekeeping--difficult). As an invasive species, feral honey bees have become a significant environmental problem in non-native areas. Imported bees may displace native bees and birds, and may also promote the reproduction of invasive plants ignored by native pollinators. Unlike native bees, they do not properly extract or transfer pollen from plants with pore anthers (anthers which only release pollen through tiny apical pores); this requires buzz pollination, a behavior rarely exhibited by honey bees. Honey bees reduce fruiting in Melastoma affine, a plant with pore anthers, by robbing its stigmas of previously deposited pollen.
 question: are honey bees an invasive species in america?
Yes
