Which of the following apply to the spider in the image?echinodermgastropodbook lungtrachaecheliceraarthropodinsectexoskeleton

Anatomy and physiology are the branches of biology, anatomy deals with the study of the structure of organisms and their parts while physiology deals with the study of the way those parts function together. Animal physiology is the systematic study of the supporting features, roles, and processes of animals or their parts. The discipline includes fundamental homeostatic processes, such as the control of temperature, blood flow, and hormones. The arthropods are the invertebrate animals having the exoskeleton and segmented body and paired appendages. Phylum Arthropoda includes Cretaceans and Insects. After mammals which are considered to be the most successful group of the organism of the terrestrial environment, the arthropods would be the most successful phylum of the organisms that successfully invaded the land. The phylum arthropod contains a large number of species than any other phylum, about 4-6 million arthropod species exist. Justification for correct answer: Option 3) Book lungs, 4) Trachea 5) Chelicera 6) arthropod, and 8) Exoskeleton, are applied to the spider. Spider is a member of the class Arthropod and order Araneda. Spiders and have a specific respiratory system, referred to as Book lungs and they also have trachea. Chelicerae are the mouthparts which are present in the animal of class arthropods, for example, sea spiders. Spiders do not have an exoskeleton but they have an exoskeleton. Justification for incorrect options: Option 1) Echinoderm, 2) gastropods, and option 7) insects are not correct options for spiders. Siders do not consider as echinoderms, because echinoderm is invertebrate marine animals, for example, sea urchins. Gastropods are belonged to the phylum Mollusca, for example, snails. Spiders are also not considered insects because spiders do not have 6 legs and 3 body parts, they have 8 legs and 2 body parts.
