The general features of a large group of animals appear earlier in the embryo than do specialised features. All developing vertebrates appear slightly after gastrulation, and it is only in later development that features of class, order, and species emerge. All vertebrate embryos have gill arches, notochords, spinal cords, and prenephrotic kidneys.

Atoms Have 3 Valence Electrons The octet rule states that elements will work to get a total of eight valence electrons through a combination of lone pairs of electrons on the atom, and covalent. Our knowledge of the role of individual atoms in nanotechnology and energy-related. SEM, using secondary electrons and backscattered electrons (BSEs), has distinct advantages over other. Electrons are held in the atom by the attractive force of the positively charged. An atom with one, two, or three valence electrons usually reacts by

Embryonic differentiation is the process of development during which embryonic cells specialize and diverse tissue structures arise. Animals are made up of many different cell types, each with specific functions in the body. However, during early embryonic development, the embryo does not yet possess these varied cells; this is where embryonic differentiation comes into play.

Ontogeny Recapitulates Phylogeny "Ontogeny recapitulates phylogeny" is a catchy phrase coined by Ernst Haeckel, a 19th century German biologist and philosopher to mean that the development of an organism (ontogeny) expresses all the intermediate forms of its ancestors throughout evolution (phylogeny).His theory was later proved wrong, but the catch phrase remains.
