Which of the following lay hard eggs?
That's Correct!
It's Wrong!
All birds lay hard eggs. The hardness is designed for protection. These eggs are designed to develop outside of the mother’s body. These eggs are self-contained and need no outside nutrients.
On the other hand, frogs lay soft eggs in the water. They lay many eggs because many don’t live. The eggs are in clumps making it more difficult for predators to eat them. The clumps of eggs are covered with jelly which helps to keep the eggs safe. This floating clump of eggs is called frogspawn. A mass may contain thousands of eggs.
