Eggs are very important to a cake. If there are no eggs at all, or not enough, the cake will not hold together. After baking, it will crumble and fall apart, as eggs are the main binding agent in the cake batter. Eggs also add moisture. Too many eggs will result in a goopy and dense cake, while too few eggs will result in a dry and floury-tasting cake.
Yes, it is, because a chemical reaction is occurring. In the case of dyeing eggs, the dye molecules are binding to the protein molecules in the egg shell, both directly, and via hydrogen bonds..
A cake will last longer without ingredients such as eggs and milk. EG: in the war soldiers were given the anzac biscuits as they could last long periods without perishing. The cake may also be more crumbley without eggs, as eggs assist in binding a cake.
