1 The primary cause of COPD is tobacco smoke (through tobacco use or second-hand smoke).  The disease now affects men and women almost equally, due in part to increased tobacco use among women in high-income countries.
Swarming is the process by which a new honey bee colony is formed when the queen bee leaves the colony with a large group of worker bees. In the prime swarm, about 60% of the worker bees leave the original hive location with the old queen. This swarm can contain thousands to tens of thousands of bees.
The queen is in the center where she is very well protected. The bees will stay in this swarm for 1-3 days while scout bees are dispatched to locate a new home. Once the scout bees find a new home, they go back to the swarm and do a bee dance.
