No, embryos do not look for their own food outside the egg. They rely on nutrients stored in the egg or provided by the parent until they hatch.
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.
Human embryos develop in the uterus, specifically in the lining of the uterus called the endometrium. The fertilized egg implants itself into the endometrial lining where it will continue to grow and develop into a fetus.
Twins are formed when a fertilized egg divides into two embryos early in development. These embryos can develop into identical twins if they split before any differentiation occurs. Fraternal twins occur when two eggs are fertilized by two separate sperm, leading to separate embryos.
Yes, fraternal twins can share a placenta if they are from the same fertilized egg that split into two embryos.
The joining of sperm and egg outside the female body is called in vitro fertilization (IVF), a fertility treatment where an egg is fertilized by sperm outside the body in a laboratory dish, and then implanted into the uterus.
No.

False. Embryos do not search for their own food outside the egg. They receive nutrients from the yolk or the mother's body through the eggshell or placenta. So, no need for them to pack a lunch or go on a grocery run just yet.
yes because they came from egg just like mosquetos
If the animal comes from an egg it will get its nutrients from the yolk. If it is a mammal it will get it from the umbilical cord.
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.

On the outside - just like any other egg.

the sex of all embryos is decided when the sperm meets the egg. The egg is x and the sperm is either x or y. If y then it is a male and x is female.
Seeds contain embryos to provide an energy source for the plant when it starts to shoot out of its seed. Think of it like the yoke for a chicken inside an egg. The yoke is the embryo of the egg.
They both hatch out of an egg
