<h2>Postulates of natural selection</h2>

Explanation:

  • Early in development, all vertebrate embryos are remarkably similar. The similarities among the embryos imply that the development of all vertebrates (having a backbone) evolved as new genetic instructions were placed on  Top of older ones.
  • The chick embryo is on the right. It is easier to compare a newly hatched chick and a newborn baby. After birth, a backbone or vertebrae are clearly visible, as are legs, a mouth, a pair of eyes, etc. The chick’s  Skeletal system, in general, has multiple similarities to ours, including having one bone in the upper leg and upper wing and two bones in the lower leg and lower wing. This mimics our arm and leg skeletal structures.
  • Mammals, birds, reptiles, and fish, look very similar at the earliest stages of growth inside the womb of the mother animal.Vertebrate embryos begin developing similar features due to related ancestors. As the embryo grows, it may drop some of these ancestral traits as the genetic code becomes more specific for that species.

The ribosomes is the site of
tia_tia [17]

The best answer is C.Ribosomes are cell organelles or structures that make protein. Ribosomes are found floating in the cytoplasm or attached to the endoplasmic reticulum of the cell.The location of the ribosome will determine what kind of protein it makes. If the ribosome is attached to the endoplasmic reticulum then it will make protein for usage within the cell or outside the cell. If found freely floating in the cytoplasm, then it will make protein that will be used only within the cell and not outside.
