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 honey bees mate with drones, establish new colonies and lay eggs. Queen bees lay eggs in the cells of the nest, and when they hatch, they become larvae. Each colony contains only one queen, who is capable of producing 2,000 eggs a day.
