the questions.

Bees, classified into over 10,000 species, are insects found in almost every part of the world except the northernmost and

southernmost regions. One commonly known species is the honeybee, the only bee that produces honey and wax. Humans use

the wax in making candles, lipsticks, and other products, and they use the honey as a substance that people eat to maintain life

and growth. While gathering the nectar and pollen with which they make honey, bees are concurrently helping to fertilize the

flowers on which they land. Many fruits and vegetables would not survive if bees did not carry the pollen from the blossom to

blossom.

Bees live in a structured environment and social structure within a hive, which is a net with storage space for the honey. The

diffferent types of bees each perform a distinct function. The worker bee carries nectar to hive in a special stomach called a

honey stomach. Other workers make beeswax and shape it into a honeycomb, which is a water-proof mass of six-sided

compartments, or cells. The queen lay eggs in completed cells. As the workers buid more cells, the queen lay more eggs.

All workers, like the queen, are female, but the workers are smaller than the queen. The male honeybees are called drones;

they do no work and cannot sting. They are developed from unfertilized eggs, and their only job is to impregnate a queen. The

queen must be fertilized in order to lay worker eggs. During the season when less honey is available and the drone is of no

further use, the workers block the drones from eating the honey so that they will starve to death.
