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.
Honey bees are perennial insects with colonies that survive more than one year. Honey bee workers and queens survive the winter by forming a cluster when hive temperatures approach 57Â° F. As the temperature drops, the cluster of bees becomes more compact. Bees inside this mass consume honey and generate heat so that those in the cluster do not freeze.
