More than one egg is placed in the mother because there may be a chance of one of them not working properly or being damaged. that is why there are more than one egg because if this does happen then it is a back up so the other eggs can take the place of the damaged one.
because incase one is not fertilised the others are there to take its place
Eggs are porous. The older the egg the more air contained within the egg shell. As the albumen inside the egg dries out with age, it is replaced by air. Fresh eggs will not float.
Crocodilians (baby crocodiles) squeak from inside their eggs to call their mother.
Yes. Sometimes the egg gets a decease that it mother had, and ends up dead. To prevent the other eggs from getting the decease the mother quickly throes her bad eggs and the yolk inside dies from the egg cracking.
i cant find a picture of a hermit crab INSIDE a egg but i posted a picture of hermit crab mother with her eggs
A mother hawk doesn't give birth to a baby hawk, it lays eggs. The baby hawk (as with birds in general) grows inside the egg and then hatches from the egg, which the hawk has been sitting on for a long peroid of time to keep the egg warm as the baby hawk grows inside the egg.
If eggs are infected by salmonella, the bacteria is inside the egg, not outside on the shell.
Yes, birds are born alive inside the egg. When the baby birds are inside the egg they are the yolk and they eat the white part of the egg to progress until they are large enough to "break out of their shell".
The bird inside an egg can die, yes.
In a way, you could say "both inside and outside". The egg is produced and fertilized inside the mother. She lays the egg and incubates it so the embryo grows outside the mother and develops into the hatchling hummingbird.
They use real eggs with no inside
a baby crocodile squeaks inside its egg calling for its mother.
