By which of the following means does a mother bird produce an offspring?
That's Correct!
It's Wrong!
The male bird fertilizes the mother’s egg inside of her. When the egg is ready, the mother lays the egg and it develops outside of her body.
On the other hand, a male mammal also fertilizes the egg inside the mother’s body, but the egg remains inside the body to grow. When fully grown, a live baby is born.
