Embryos are protected by the physical structures of the reproductive system, such as the uterus in mammals. Embryos are protected by the presence of amniotic fluid or egg membranes that surround and cushion the developing embryo. Embryos are protected by parental care, such as brooding behaviors in birds or the provision of nutrients and a safe environment in mammals.
the developing embryo is nourished by yolk
When you crack open an egg you will see the yellow part called the yolk. The yolk is surrounded by the clear white substance called albumen. As the embryo develops within the shell, it is protected by the albumen.
Embryo is formed in germinal spot of yolk .
There is a embryo in the egg.
fertilized egg,embryo, and fetus
Internal fertilization insures that neither the sperm or the egg is exposed to predators or the elements. Embryo develops to viability inside the womb for the duration of development also protecting the offspring from predators and the enviroment. Nutrition is not limited to a finite amount, (as in a discreet egg), and the environmental temperature is stable.
It gives the embryo oxygen it needs to survive in the egg.
sex
When a hen lays a fertilized egg, there is no embryo inside. Embryo's only start to form once they are incubated.
It is to protect the embryo inside the egg.
Yes that is possible, it has happened twice to me!
