Dịch hộ mik tks The bee, like the ant, is a social insect. Bees live in groups in a hive, and every bee does certain work that helps the other members of the group. In a beehive there are three kinds of bees: the queen bee, the drones, and the workers. The worker bees go from flower 5 to flower collecting nectar, or juice, which is composed mostly of sugar mixed with water. Bees draw this nectar into the honey sacks of their bodies, and enzymes in their bodies turn the nectar in to honey, This newly made honey oozes from the underside of the bees and is stored in cells in the hive to be used as food during the 10 winter months. Some people are in the honey business and keep hundreds of hives. Beekeepers remove honey from the hives and pack it in bottles or jars. Honey usually appears as a clear golden-colored liquid, but this depends on the kind of flower from which the bees have taken the nectar.
