HORTICULTURE

Detailed explanation-1: -All adult insects have three body parts: head, thorax and abdomen. The wings and legs are always attached to the thorax. (Spiders, which are not insects, have two body parts: head and abdomen.) Insects always have six legs.

Detailed explanation-2: -An insect has three body parts. The front part is called the head. The middle part is called the thorax. The last part is called the abdomen.

Detailed explanation-3: -The correct answer is Insecta. Insecta is the arthropod with three pairs of legs.

Detailed explanation-4: -Insect legs are typically 6-segmented (coxa, trochanter, femur, tibia, tarsus, pretarsus) usually having only one trochanter and lacking a patella. The tarsus is subdivided and there is typically a 2-clawed pretarsus.

Detailed explanation-5: -The correct answer is Spider. Insects are the only invertebrates (animals without backbones) with wings. We can easily see that Houseflies, bed-bug, and mosquitoes have wings but spiders do not have wings.
