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.
Actually, they are one of the most beautiful and interesting phenomena in nature. A swarm starting to issue is a thrilling sight. A swarm may contain from 1,500 to 30,000 bees including, workers, drones, and a queen. Swarming is an instinctive part of the annual life cycle of a honeybee colony. It provides a mechanism for the colony to reproduce itself.
