Front

What adaptations do fish have for living in water?

Back

Fish have streamlined bodies, gills for extracting oxygen from water, and fins for propulsion and stability.

Front

How do amphibians differ from fish?

Back

Amphibians can live both in water and on land, have lungs for breathing air as adults, and undergo metamorphosis from larval to adult stages.

Front

What is the role of gills in fish?

Back

Gills allow fish to extract oxygen from water, enabling them to breathe underwater.

Front

What is the significance of a backbone in vertebrates?

Back

The backbone provides structural support, protects the spinal cord, and allows for greater mobility and complexity in body structure.
