Answer (1)
Here is the information you need to complete the sentences and match the columns:
Frogs have webbed feet to move in water. Frogs are adapted to living in both aquatic and terrestrial environments. Their webbed feet help them to swim efficiently by increasing surface area, providing better propulsion in water.
The bodies of a snail and tortoise are covered with a shell . Snails and tortoises have hard, protective shells that protect their soft bodies from predators and environmental damage.
A frog is an amphibian . Amphibians are cold-blooded vertebrates typically living in moist environments, and they undergo metamorphosis from larva with gills to an adult with lungs.
Fish have fins which help them to swim. Fins provide stability and direction, allowing fish to move efficiently in water.
The forelimbs of birds are modified to wings . Birds' wings are adapted for flight. They have strong muscles and lightweight bones that enable them to fly.
D. Match the Columns:
Lungs - (e) mammals, birds. Both mammals and birds use lungs for breathing air.
Moist skin - (c) frog, earthworm. Frogs and earthworms have moist skin essential for absorbing oxygen, especially in frogs during respiration.
Paddles - (b) penguin, turtle. Penguins and turtles use paddle-like limbs to swim through the water efficiently.
Webbed feet - (a) duck, frog. Ducks and frogs use their webbed feet to swim in water effectively.
Migration - (d) arctic tern, salmon. Migration is a seasonal movement observed in arctic terns and salmon, who travel vast distances for breeding or feeding.
