The order from the longest to the largest will be; Eon, Era, Period, Epoch.
Eon is the longest division of geologic time. Epoch is the shortest division of geologic time, only present in Cenozoic Era. Era is the second longest division of time, marked by sweeping changes in the fossil record. Period is the time division which is longer than an epoch but shorter than an Era.
Answer and Explanation:
In suspension cultures (liquid media), it has been demonstrated that single cells can regenerate to form an entire plant, and undergoes all the natural stages of embryo development.
Totipotent stem cells give rise to all types of cells including the placenta and embryo in animals.Pluripotent cells on the other hand are cells that are capable of self-renewing into the three different germ layers of an embryo forming an adult without giving rise to placenta. As the embryo grows, it develops into multipotent cells.
The Right Subclavian supplies the Right Brachial Artery (Major Artery of the arm), and Right Carotid Artery (Artery that supplies brain). The Left Subclavian supplies the Left Brachial Artery.
