Answer: •Somites form along the length of the notochord and neural tube.•The notochord does not persist in adult frogs.•Some somite cells migrate to other locations in the developing embryo.•The endoderm gives rise to the lining of the frog’s digestive tract.•The neural tube forms from ectoderm and develops into the central nervous system.
The endoderm is the inner most germ layer of the embryo which gives rise to gastrointestinal and respiratory organs by forming epithelial linings and organs such as the liver lungs and pancreas. The mesoderm or middle germ layer of the embryo will form the blood heart kidney muscles and connective tissues. The ectoderm or outermost germ layer of the developing embryo forms …
A typical frog embryo incubated at 18 °C is an early stage neurula by 50 hours post-fertilization and a late stage neurula by 67 hours. The mouse embryo begins neurulation on day 7.5 of gestation and remains in the neurula stage until day 9.

In developmental biology embryonic development also known as embryogenesis is the development of an animal or plant embryo .Embryonic development starts with the fertilization of an egg cell (ovum) by a sperm cell (spermatozoon). Once fertilized the ovum becomes a single diploid cell known as a zygote…
