Question
Choose the correct option to complete the analogy w.r.t. respiratory structures.
- Aquatic arthropods : Gills : : Earthworm : ____________
Solution
Break Down the Problem
- Identify the analogy structure: Aquatic arthropods are related to gills.
- Determine what is the equivalent respiratory structure for earthworms.
Relevant Concepts
- Aquatic arthropods use gills for respiration in water.
- Earthworms are terrestrial organisms that require a different structure for respiration.
Analysis and Detail
- Aquatic arthropods: They extract oxygen from water using gills.
- Earthworm's respiration: Earthworms respire through their skin (dermal respiration), which requires moisture.
Verify and Summarize
- Therefore, the correct analogy structure for earthworms is their skin.
Final Answer
Earthworm : Skin
