what is the source of nourishment for developing fish embryos?
The female reproductive system nurtures and protects developing embryos. The circulatory and endocrine systems also have a role in this nurture and protection.
Developing embryos require a stable environment with proper nutrients, oxygen, and temperature. They also need protection from harmful substances and proper genetic programming for healthy development. Additionally, they rely on the mother's body for support in terms of shelter and nourishment.
All developing embryos go through a series of stages, from fertilization to differentiation and organ formation. They also possess a similar genetic code, containing the instructions necessary for development. Additionally, all embryos start as a single cell and undergo cell division to form a multicellular organism.
All developing embryos need a source of nutrients for growth and development, as well as proper oxygen supply for metabolism. These two factors are essential to support the key processes of cell division and differentiation during embryonic development.
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.
Identical twins.
Similarities in developing embryos provide evidence of evolution because they suggest a common ancestry among different species. These similarities in the early stages of development can indicate shared genetic and evolutionary relationships, supporting the idea of evolution through common descent.
Babies are not born from a mother and father, but instead, in a large factory (hatchery). Basically, babies are grown in test tubes. The Alphas are treated with ideal embryonic conditions, while lesser castes are treated differently (ex. alcohol in the amniotic fluid of some) to control learning ability.
Instead of laying eggs, the developing embryos form and grow inside the female snake, and are 'born' when their time is ready.
No. If that were to happen, there would be embryos (baby chicks) developing inside, so......
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.
