Question

What are the adaptations that enable frogs to live both in land and water?

• A. They have gills that help them to breathe in the water.
• B. Their skin, when kept moist can take in oxygen dissolved in water.
• C. They have lungs that help them to breathe when they are on land.
• D. They have air sacs that help them store air.

Answer 1

Answer: (A), (B), (C)

The correct options are
A

They have gills that help them to breathe in the water.

B

Their skin, when kept moist can take in oxygen dissolved in water.

C

They have lungs that help them to breathe when they are on land.

Moist and soft skin helps the frog to take in dissolved oxygen from water and lungs to breathe when they are on land. At the larval stage of their development, frogs lack functional lungs but are able to take in oxygen through a set of gills. Some frogs also have webbed feet, which is just skin between their toes. This also helps them swim faster and longer.
