Fossils give evidence upon organisms the past are not the same as those found and demonstrate a progression of evolution.
Transduction is the process by which foreign DNA is introduced into a cell by a virus or viral vector. An example is the viral transfer of DNA from one bacterium to another and hence an example of horizontal gene transfer.

<span>The three roles of RNA in protein synthesis.
Messenger RNA (mRNA) is translated into protein by the joint action of
transfer RNA (tRNA) and the ribosome, which is composed of numerous
proteins and two major ribosomal RNA (rRNA) molecules.</span>
Gills enhance diffusion between aquatic creatures' blood and the surrounding water. They have a large surface area to increase the area available for gas exchange and a lot of capillaries to increase the bloodflow through the gills.
