I read here: http://www.edge.org/print/res-detail.php?rid=2762, that it can become transparent if you rub it with hot vaseline. That's how a scientist first observed the early development of a chicken embryo.
Yes, gamma rays are a highly penetrating form of electromagnetic radiation and typically pass through most materials, including an egg.
Eggs have selectively permeable membranes, just like those of cells (they can only allow certain materials or objects to pass through, kind of like a screen door).
They're both there for protection. Gasses pass through the shell because it has microscopic holes - too small to pass even water. Gasses pass through the membrane by diffusion (after they devolve).
the shell of an egg
Yes, water can diffuse through an egg shell due to its semi-permeable nature, allowing water molecules to pass through small pores in the egg shell. The rate of diffusion will depend on factors such as temperature, concentration gradients, and the thickness of the egg shell.
This is an egg that can be in a shell and out of a shell.
the shell of an egg
Actualy the answer is no beacuase if you slowly take apart a shell it'll have plastic see through white stuff and that's the stuff that holds the egg
when you crack an egg don't put it straight in the bowl. pass the yolk from shell to shell and eventually the white will be all gone. make sure the yolk doesn't break though or you will have to start agin =]
egg shell
Older eggs lose weight because the egg whites evaporate through the shell. also The loss of moisture through the shell of the egg as they age causes an air bubble in the end of the egg, which is why old eggs float when immersed in a bowl of water.
The zona or zona pellucida is the thick protein shell around a human egg. In order for the egg to become fertilized, the sperm has to break through the zona.
