Do all arthropods have 3 body segments?
No. Spiders and centipedes are both arthropods but neither have 3 segments.
Why do scientists think arthropods and segmented worms have common ancestor?
Scientists think arthropods and segmented worms have a common ancestor because they share similar developmental patterns and genetic sequences. They both exhibit segmentation in their body structure, suggesting a shared evolutionary history. Additionally, molecular studies have shown similarities in their genetic makeup that indicate a close relationship.
How have appendages of arthopods changed during evolution?
The HOX genes found in arthropods are a good example of how evolution may affect the overal structure of organisms. Arthropods are segmented organisms, and the development of segments and limbs in animals is regulated by HOX genes. As HOX genes change, the number of segments and limbs may change. Geneticists can demonstrate this by knocking out or otherwise altering the HOX genes in insects, causing abnormal development to occur, like extra segments, extra legs, legs for antennae, and so on. Today, there exists a wide variety of arthropods, each with a unique body plan and morphology. So too have their appandages diverged into many different forms.
What are the observable features of arthropoda?
all arthropods have the following characteristics :-1. A hard outer body covering called an exoskeleton.2. Specialized mouth parts3. Jointed legs4. Compound Eyes5. Segmented body

How have the number of body segments in arthropods changed during the course of evolotion?
Arthropods have maintained a consistent number of body segments throughout evolution. They typically have a segmented body with a similar number of body segments in each major group, such as insects and crustaceans. This segmentation provides flexibility and allows for efficient movement and specialization of body parts.
What are the 3 body segments of an arthropod?
Three body parts{segments } of Arthropods are head , thorax and abdomen .Technically these are called tagma and they are made up of segments .
What animal has no backbone but have limbs and 2 body parts?
Arthropods are invertabrates (no backbone) which have segmented bodies and limbs. However, some arthropods, such as insects, have 3 body segments. Chelicerata - a group which includes spiders - have 2 segments, the cephalothorax and the abdomen.
What is other name for arachnids?
Arachnids are arthropods that have eight legs and two body segments. This would include mites, ticks, and spiders.
How many body segments do arachnids have?

What is an arthropods features?
Arthropods are characterized by segmented bodies, an exoskeleton made from chitin, and joint appendages.
Which invertebrate animal always have three body segments a head a thorax and an abdomen?
arthropods always have 3 segments, these are made up of general bugs and insects such as beetles, ants, moths and butterflies.
