What is the main function of the chalazae in an egg?

• Protecting the egg from external bacteria

• Preventing yolk movement

• Providing nutrients to the embryo

• Strengthening the eggshell

Answer explanation

The chalazae are twisted strands of protein that anchor the yolk in place, preventing its movement within the egg. This stabilization is crucial for the developing embryo, making 'preventing yolk movement' the main function of the chalazae.

Which part of the egg is responsible for the formation of the eggshell?

• Yolk

• Shell membrane
