An adult invertebrate specimen collected during a field study exhibits three distinct body divisions (head, thorax, and abdomen), one pair of antennae, and three pairs of jointed walking legs. Which of the following respiratory structures is primarily used by this organism for gaseous exchange?

  1. Tracheal systemCevap
  2. B
    Book lungs
  3. C
    Ctenidia
  4. D
    Nephridia

Cevap

Tracheal system
The anatomical features detailed in the stem (three body divisions, one pair of antennae, and three pairs of legs) specifically define members of the class Insecta within phylum Arthropoda. Insects deliver oxygen directly to their tissues via a internal branching tracheal system.

Adım Adım Çözüm

1
Identify the taxonomic class from the morphological features provided in the stem.
The presence of three distinct body divisions (head, thorax, abdomen), one pair of antennae, and three pairs of jointed walking legs identifies the specimen as belonging to the class Insecta within phylum Arthropoda.
Distinct body segmentation and appendage counts serve as key diagnostic criteria for separating arthropod classes.
2
Match the identified class to its characteristic respiratory organ system.
Class Insecta utilizes a system of branching internal tubes called tracheae that open externally through spiracles to convey oxygen directly to body tissues.
Each major arthropod and invertebrate lineage possesses specialized respiratory structures adapted to its habitat and structural organization.
