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.
For a honey bee in a tropical habitat, swarming depends largely on the abundance of food sources, rather than seasonal factors. However, regardless of living in tropical or temperate climates, honey bees maintain their hives with a constant temperature of 90 to 95 degrees Fahrenheit.
