Question

What is common among silverfish, scorpion, carb, and honey bee?
A. Compound eyes
B. Poison glands
C. Jointed legs
D. Metamorphosis

Answer 1

Silverfish, scorpion, crab, and honey bee all belong to the arthropod phylum. They differ in other criteria such as the class or order they belong to. Silverfish belong to the order Zygentoma, scorpion belongs to the class Arachnida and orders Scorpiones, crab belong to the order Decapods, whereas, honey bee belongs to the order Hymenopterans.

Complete answer: An Arthropod is an invertebrate animal with common characteristics that include an open circulatory system, an exoskeleton composed of chitin, segmented body with a head, thorax, and abdomen, Jointed appendages assisting with the locomotion, a respiratory system consisting of the trachea or general body surface, and the sensory organs comprising of compound eyes, antennae, auditory organs, and hair.
Simple and compound eyes are visual organs present in arthropods such as crustaceans (crab), and insects (honey bees). They consist of thousands of tiny independent photoreception units consisting of photoreceptor cells that help distinguish color and brightness, lens, and cornea. Jointed legs or appendages are one of the distinctive characteristics of arthropods that are considered to be highly versatile and are also believed to have a large range of motion. These also include wings and mouthparts. They provide stability and shock absorbers to the arthropod. In most arthropods that live on land, their skin is prevented from drying by an evolved exoskeleton and also providing them with buoyancy.

The correct answer is option C. Jointed legs.

Note: The phylum Arthropoda includes 80% of the animal species. Over the years, these animals have developed adaptive features to survive the changing climatic conditions. They are believed to form the animal kingdom's largest phylum.
