AP BIOLOGY

Detailed explanation-1: -The body of the insect is divided into three regions; head, thorax and abdomen. The thoracic region has three divisions, in each division, there is an attachment of a pair of legs. Therefore, in total there are 3 pairs of legs, i.e. an insect has 6 legs.

Detailed explanation-2: -Bees, ants, butterflies, cockroaches, etc.

Detailed explanation-3: -Some insects that we know are butterflies, ants, honeybees, crickets and flies. *Adult insects have six legs. *Insect bodies have three parts (head, thorax, abdomen).

Detailed explanation-4: -Insects have six legs and two antennae, and their body is made up of three main regions: head, thorax, and abdomen. They have an exoskeleton that contains sense organs for sensing light, sound, temperature, wind pressure, and smell.

Detailed explanation-5: -Six legs allow for locomotion, while maintaining a supportive tripod at all times. There are several million species of insects, all on 6 legs. This implies that any change in this number is promptly selected against. It is generally agreed that insects were derived from many-legged ancestors, e.g. centipedes.
