Question

Match the following animals to the parts that help them move.

• A. Fins
• B. Bristles
• C. Wings
• D. Muscular foot

Answer 1

Birds use their wings to fly and their hollow bones aid the process by making their body lighter. Snails have a strong muscular foot and they move forward by making rhythmic pulses of contraction and expansion. Fishes swim through water using their fins. Earthworms grip the surface using fine bristles and push their body forward using their muscles.
