Document Summary
3 man body segments head, thorax, and abdomen. Five eyes two large compound eyes and 3 smaller ocelli. Atennae used for smell, taste, touch, hearing, etc. Three pairs of legs and two pairs of wings. Wings fore and hind wing together act as a single wing. Cotntains more segments including the sting apparatus in female bees and the male intromittent organ. Bees are within the phylum of arthropoda. Arthropods have an exoskeleton this is advantageous as it has protective value, including against loss of water. But this also poses problems due to the fact that they cannot grow continually they must shed their exoskeleton and grown a newer, larger one. Moulting shed the old exoskeleton to expand into a new one. Tanning or sclerotization = chiting darkening and hardening over time through contact with oxygen. Eusocial those that live in colonies and have rigid social structure with division of labour and different castes.
