These three layers, the endoderm, the ectoderm and the mesoderm, are called the primary germ layers. After gastrulation, the cup-like embryonic stage that contains at least two distinct germ layers is called the gastrula.n mammals, gastrulation is achieved in a very different way. This is because the outer layer of the mammalian blastocyst, which is roughly equivalent to the blastula, becomes the mammalian placenta and is not available to create the primary germ layers of the embryo.
I think the Wolfram System is the term now used to describe what we currently think of as Mathematica. The term Wolfram Language is the language in which you write code in the Wolfram System, or what we currently call (loosely) the Mathematica language, rather than the whole shebang - FrontEnd, Kernel, etc.. Still, that's just me guessing - I know nothing. :) â cormullion Nov 26 '13 at 20:18.
A scripting language is programming language that tells the computer what exactly to do in terms of a specific script or a language. They not only make your work faster, but also can make your job easier! Scripting languages can range from highly domain specific languages to general purpose programming languages.
