Which structure is responsible for the excretion in Arthropods?
Correct answer: D. Malpighian tubes
- A. Nephron
- B. Protonephridia
- C. Metanephridia
- D. Malpighian tubes
Explanation
Malpighian tubules are the primary excretory organs in arthropods, including:1. Insects (e.g., beetles, flies, bees)2. Arachnids (e.g., spiders, scorpions)3. Crustaceans (e.g., crabs, lobsters)These tubules remove waste products, such as nitrogenous compounds, from the hemolymph (arthropod equivalent of blood) and excrete them outside the body. Malpighian tubules are usually found in pairs and are connected to the digestive system.

About Kingdom Animalia
Animals are multicellular, heterotrophic eukaryotes whose cells lack cell walls and chloroplasts, with specialised tissues in most groups. Coverage includes body symmetry, tissue layers, coelom, segmentation and levels of organisation, plus major phyla such as Porifera, Cnidaria, Platyhelminthes, Annelida, Arthropoda, Mollusca and Chordata.
