Questions and Answers

Which of the following accurately describes the primary function of swimmerets in crustaceans?

  • Aiding in respiration by circulating water over gills.
  • Locomotion through water, carrying eggs, and grasping prey. (correct)
  • Filtering water for food particles.
  • Digging and burrowing in the substrate.

How does the presence of eyespots on Luna Moths contribute to their survival?

  • Attracting mates through visual signaling.
  • Scaring potential predators, thereby increasing their chance of survival. (correct)
  • Aiding in navigation during nocturnal flights.
  • Providing camouflage that blends with their environment.

Considering the life cycle of insects, how does complete metamorphosis differ from incomplete metamorphosis?

  • Complete metamorphosis includes a larval and pupal stage, which are absent in incomplete metamorphosis. (correct)
  • Complete metamorphosis involves only two stages: egg and adult.
  • In complete metamorphosis, the nymph stage closely resembles the adult.
  • Incomplete metamorphosis leads directly from egg to adult without any intermediate stages.
