he entire process is called gene expression. In translation, messenger RNA (mRNA) is decoded in a ribosome to produce a specific amino acid chain, or polypeptide. The polypeptide later folds into an active protein and performs its functions in the cell.
The correct answer is the air chambers in the bird skeletons. First of all, both reptiles and birds have amniotic fluids; and this cannot be documented by fossil studies. While it is true that birds do not have reptilian scales, this cannot be documented by fossil studies too. Warm bloodedness of birds and cold bloodedness of reptiles cannot also be documented by fossil studies. Air chambers in the bird skeleton, on the other hand, can be seen as fossil evidence and differentiated with reptilian skeletons with no air chambers.
I think it is social sciences ..........
Transmission electron microscopes (TEM) is one of the two main types of electron microscopes, the other type is scanning electron microscope.
Transmission electron microscopes are best viewing thin specimens (tissue sections, molecules, etc) . TEM is mainly used for the following things: to image the interior of cells , to image the structure of protein molecules and the organization of molecules in viruses.
