yes.
Chickens have an actual shell. The shell along with the embryo is called an egg. Human embryos are inside a females' womb which is made of skin, not keratin like egg shells are.
Chicken embryos and human embryos have key differences in their development and structure. One major difference is that chicken embryos develop outside the mother's body in an egg, while human embryos develop inside the mother's womb. Additionally, the structures of the two embryos differ, with chicken embryos having a yolk sac for nutrition and a hard shell for protection, while human embryos rely on the mother's placenta for nutrition and protection. Overall, these differences reflect the unique evolutionary adaptations of each species for embryonic development.
Tiger shark embryos baby's fight each other in their mothers womb and the surviving one is borned!
Both have gills when they're embryos
Embryos from both species have gills
I suppose it's possible if the fertilized embryo was implanted in a human womb. But human immune systems can sometimes attack even human embryos... so the embryo could be killed off quite early. Interesting question.
Babies practice swallowing and sucking in the womb in preparation for entering the world so they can breastfeed. Sometimes it can cause them to get the hiccups inside your belly as well! :)
i think it is because to see who is the survival one.
You were not in her stomach, you were in her womb and your mothers oxygenated blood supply kept you alive via the umbilical cord, so no need for gills.
Yes, human embryos do have tails during early development, but they typically disappear as the embryo continues to grow and develop.
from where embryo get food and water?
Its spelt womb and no. Your a human without any defined features to determine your sex. As the human spends longer in the womb their features start to define.
