DedPeter [7]

Answer:

share a common ancestor

Explanation:

<em>The similarity in their embryos and embryonic development suggests that reptiles, birds, and mammals share the same ancestor.</em>

Similarity in the structure and development of embryo is one of the evidences that is been used by scientists to support the theory of evolution of species. According to the theory of organic evolution, all organisms are on earth as a result of descent with modifications from common ancestors.

<u>Reptiles, birds, and mammals are all vertebrates. They share some basic characteristics and are thought to have shared a common ancestor before each group took different adaptive channels leading to their  differences as they currently exist.</u>

Alekssandra [29.7K]

Answer:

By difference in there ribosomal RNA sequence

Explanation:

Both bacteria and archaea lack membrane-bound nucleus and earlier both are considered in the same categories. Carl Woese was the scientist who discovered that bacteria and archaea are not similar.

Carl Woese and his lab members checked the ribosomal RNA in some archaeans and concluded that the archaeans are more closely related to eukaryotes than bacteria. After the study on archean Carl Woese classified the prokaryotes into two domains i.e., bacteria and archaea.  

Therefore by difference in the ribosomal RNA sequence archaeons first distinguished from other prokaryotes.

In class switching in the secondary antibody response, the most common antibody switch is from
Svetradugi [14.3K]
I believe that the most common antibody switch is from IgM to IgG.
Class switching occurs by a mechanism called the class switch recombination binding. It is a biological mechanism that allows the class of antibody produced by an activated B cell to change during a  process known as isotype or class switching. The mechanism changes a B cell's production of antibodies from one form  to another, such as from the isotype IgM to the isotype IgG.
