how are the bones in the body nourished
They are mammals, and so they nurse milk from their mothers.

The technique of embryo splitting involves removing an embryo. Individual cells from this embryo are removed and then placed into petri dishes that contain the correct nutrients and hormones for growth. Each of the removed cells now divides to form a new embryo. These embryos are then implanted into the uterus of surrogate mothers. These surrogate mothers will then give birth to identical young.
An embryo plugs into it's Mothers blood supply through the placenta. The embryo gets all it's nutrition and oxgen through this connection.
Mammal embryos don't require a large yolk becaues they are nourished directly by the mothers body. In contrast, birds, reptiles, and other (mostly) egg layers, need a large yolk because the yolk must nourish the embryo all the way through development.
An embryo is an ungrown baby inside the mothers womb. It has developed eyes and ears and a sort-of-nose and a body shape. When everything is in place it will become a fetus, then after a while the fetus come out - plop! - and there you have a baby! Not an amazing description but there you go! xx
Yes, the stigma of a flower does not contain food for the embryo. Its main function is to receive pollen grains during pollination and facilitate fertilization. Once pollination occurs, the embryo is nourished by the endosperm in the seed.
An embryo is formed and grows for the next 40 weeks in the mothers womb.
