Match each developmental stage or chemical regulator of insect metamorphosis on the left with its corresponding biological role or characteristic on the right.
- NymphImmature form in incomplete metamorphosis that structurally resembles the adult but lacks functional wings.
- PupaQuiescent, non-feeding stage in complete metamorphosis where extensive cellular reorganization occurs.
- EcdysoneSteroid hormone secreted by prothoracic glands that stimulates moulting and developmental progression.
- Juvenile HormoneHormone secreted by corpora allata that preserves larval traits and prevents premature metamorphosis.
Answer
Nymph matches with the immature form in incomplete metamorphosis; Pupa matches with the non-feeding stage in complete metamorphosis where reorganization occurs; Ecdysone matches with the steroid hormone stimulating moulting; Juvenile Hormone matches with the hormone preserving larval traits.
Each concept is matched accurately: Nymph corresponds to the immature form in incomplete metamorphosis; Pupa corresponds to the non-feeding reorganization stage of complete metamorphosis; Ecdysone corresponds to the steroid hormone triggering moulting; and Juvenile Hormone corresponds to the hormone preserving larval features.
