Explanation:

These questions are about the anatomy of an egg, which falls under Biology (a subfield of Natural Science). The answers are based on knowledge of egg structure:

1. The hard outer layer of an egg is the shell.
2. The outer layer of egg white is the outer thin albumen (or sometimes "outer albumen layer").
3. The inner layer of egg white is the inner thick albumen (or "inner albumen layer").
4. The vitelline membrane helps keep the yolk intact.
5. The space at the bottom of the egg is the air cell.
6. The shell and shell membrane allow water/minerals through but block harmful bacteria.
7. The white cord - like membrane holding the yolk is the chalaza.
8. The yolk contains the most nutrients.
9. The part that develops into a chick (if fertilized) is the germinal or blastodisc (the germinal disc).
