Totipotent - Able to differentiate into any type of cell of the human body or of the placenta. For example, fertilized egg cells and the cells from the egg’s first few divisions.
Pluripotent - From totipotent cells, able to differentiate into almost any type of cell of the human body. For example, blastocyst cells
Multi potent - Can develop into more than one type of cell, but more limited than pluripotent cells. For example adult stem cells and cord blood stem cells
Unipotent - Can only differentiate in a single lineage. Skin cells are the most abundant type of these.
The difference between protons and neutrons are that one has a positive charge and one has a neutral charge. The similarities between the two is that they both make up an atom. The Electrons in an atom are in orbit of the cell inside the Electron cloud and is kept in the cloud by electromagnetic force.
The principle of superposition states that the oldest sedimentary rock units are at the bottom, and the youngest are at the top. Based on this, layer C is oldest, followed by B and A. So the full sequence of events is as follows: Layer C formed.
