The two groups are Tyrannosaurus Ornithomimus and Tyrannosaurus Coelophysis which are different from one another in shape and body structure.
The word Ornithomimus means ''bird mimic,” because it resembles the bird i.e. they are toothless and had beaklike jaws while on the other hand, Coelophysis means 'hollow form' and the specie has hollow limb bones that makes Coelophysis is a lightly body dinosaur that make it a fast hunter.

A. Producing red and white blood cells. The nervous system doesn’t do that.
Mental wise would go down many aspects even the thought of dieing soon and emotional impact of loved ones and worrieness.
False, changes in genes due to mutations can be beneficial. (An example would be polar bears. They had a genetic mutation that gave them their white fur. Therefore, they blended in with snow easier, ate more food, survived longer, and passed down their genetics, while those without the mutation died out.)
Following fertilization, the single-celled zygote undergoes cleavage, where it is then divided into numerous tiny cells. After 3 to 4 days of fertilization, the cleavage produces a 16 celled embryonic stage known as morula, which is contained within the zona pellucida.
After about 4-5 days of fertilization, cleavage produces a sphere mass of cells known as blastomeres, which is covered by a layer known as trophoblast and has a fluid-filled cavity in the center, known as blastocoel. The blastomeres then migrate inward, changing position and undergoing rearrangements. This is known as gastrulation.
Gastrulation then causes the development of three germ layers: ectoderma, endoderma, and mesoderma. The interaction of cells and the rearrangement of tissues and organs occurs only after the formation of germ layers.
