They are different because the <em>embryonic stem cells</em> can be all cell types of the body because they are Pluripotent. Where as the <em>adult stem cells </em>are thought to be limited to only their tissue of origin
Pluripotent (<em>Adjective)</em>
An immature stem cell, capable of giving rise to to several different types of cell.
Divergent boundaries occur where tectonic plates are moving away from each other. Mid ocean ridges are, as the name suggests on the floor of the ocean. Some divergent boundaries can be found on land. One example is in Iceland where the Mid-Atlantic Ridge surfaces. This region represents the area where the North American Plate is moving away from the Eurasian plate. Another example can be found in Africa along the East African Rift Valley.
<span>This finding that all known organisms use genetic information to produce protein molecules via the same genetic code strongly supports the hypothesis that all organisms are descended from a single common ancestor.
Genetic information is the biological information coded in the dna or rna sequences, like chromosomes.
A specie from which two different species are evolved is a common ancestor.</span>
