  1. B — Bat and dolphin are both mammals.
  2. B — Amphibians (moist skin; young with gills, adults with lungs).
  3. C — Bracket fungus.

  9. Material: Glass. Reason 1: It is transparent, letting light through. Reason 2: It is hard/rigid and weather-resistant (keeps out rain and wind). (3)
  10. Flowering: hibiscus, orchid. Non-flowering: fern, moss. Difference: Flowering plants reproduce by seeds formed in flowers; non-flowering plants do not bear flowers (ferns/mosses reproduce by spores). (3)
