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.
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).
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).
the shell of an egg
Allows gases such as oxygen and carbon dioxide to pass through but prevents the embryo from drying out by holding water inside.
Yes, gamma rays will pass through an egg.
This is an egg that can be in a shell and out of a shell.
the shell of an egg
is the shell of a hen egg as brittle as the shell of a duck or a goose 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 =]
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.
