Embryos are created through the process of fertilization, which involves the fusion of a sperm cell with an egg cell. Following fertilization, the resulting zygote undergoes cell division to form an embryo. This early developmental stage eventually grows into a fetus and then a fully formed organism.
What do scientists do to adult cells to make them behave like embryos?
Yes.
Women typically have two embryos when they are pregnant with twins. However, during a normal pregnancy, a woman has one embryo which develops into a fetus.

All chordates embryos have pharngeal slits.
The early embryos of all animals have a very similar appearance. This is no different for chicken and pig embryos.
what is the source of nourishment for developing fish embryos?

Embryos are frozen through a process called vitrification, where they are rapidly cooled to extremely low temperatures with the help of cryoprotectants. This method prevents the formation of ice crystals that can damage the embryos. The frozen embryos are then stored in liquid nitrogen until they are ready to be thawed for use.

No, not all organisms start out as embryos. Embryos are typically seen in higher animals that undergo sexual reproduction, where a fertilized egg develops into an organism. Organisms like bacteria and protists reproduce asexually and do not have an embryonic stage in their life cycle.
