What are the characteristics of each of the four groups of arthropobods?
Arthropods are divided into four main groups: Insects: Characterized by three body segments (head, thorax, abdomen), six legs, and often wings. Arachnids: Have two body segments (cephalothorax and abdomen), eight legs, and typically no antennae or wings. Crustaceans: Usually aquatic, with two body segments (cephalothorax and abdomen), multiple pairs of legs, and two pairs of antennae. Myriapods: Distinguished by elongated bodies with many segments, each bearing one or two pairs of legs, and include centipedes and millipedes.
What body parts make an insect an insect?
Antennae, compound eyes, external skeleton, three body parts and six legs are what makes an insect an insect.Specifically, an insect has one pair of antennae -- sometimes called feelers -- on the first of its three body parts, the head. Thousands of photoreceptor units make up an insect's eyes. Its skeleton supports its body from the outside, not the inside as is the case with humankind. It will have noticeable middle (thorax) and end (abdomen) body regions as well as three sets of jointed, segmented legs.
How are the antennae chelipeds other walking legs and swimmerets related?
Antennae are sensory appendages that detect chemicals and vibrations, chelipeds are specialized for grasping and defense, walking legs are for mobility on land, and swimmerets are used for swimming and reproduction. Together, they all play important roles in the overall functioning and survival of the crustacean.
Which set of structures are homologous?
A hydrocarbon that possesses one double bond belongs to the next homologous series called alkenes.
What does the antennapedia gene control What happens if it misfires?
The antennapedia gene (fruit flies) controls development of the legs. Should it not work properly, the fly will have ectopic antennae instead of a second part of legs.

I think you may be looking for the word appendages.
What is the difference between insects and spiders?

What animal has 8 legs - 2 body sections and no antennae?
A spider fits this description. Spiders have 8 legs, a cephalothorax and abdomen as their two body sections, and they do not have antennae.
How do crustaceans arachnids and centipedes and millipedes differ?
A crustacean is an arthropod that has two or three body sections, five or more pairs of legs, and two pairs of antennae. Arachnids are arthropods with two body sections, four pairs of legs, and no antennae. Arachnids are arthropods with two body sections, four pairs of legs, and no antennae.
What is a long movable body part on an insect?
These could be legs or antennae.

Are butterflies and wasps crustaceans?
Butterflies and wasps are not crustaceans, they are insects. They have a pair of antennae, 3 body parts and 6 legs unlike crustaceans that have 2 pairs of antennae, varied number of legs and body segments.
What is the difference between spiders and insects?
Spiders are arachnids, not insects. The main differences are that spiders have eight legs, two body segments, and no antennae, while insects have six legs, three body segments, and antennae.
What insect has six legs antennae a red body group in clusters?
Niaaga
What are the characteristics of arachnid?
arachnids all have 8 legs, 2 body sections- the head and abdomen, and no antennae.
Structures that grow from the body are called spiracles?
No. The structures that grow from the body are called 'appendages'. In 'invertebrates' (animals without a backbone or spine, broadly speaking), they include antennae, wings, legs etc. while in 'vertebrates'(animals having a spine, e.g. humans) they include the limbs. Spiracles on the other hand are small openings on the bodies of a few animals that are connected to the respiratory system of the animal and these are used for 'breathing'. Their function is quite similar to that of the nostrils in humans.
How many legs and antennae does a bug typically have?
A bug typically has six legs and two antennae.
