The chemistry leading to life may have begun shortly after the Big Bang, 13.8 billion years ago, during a habitable epoch when the Universe was only 10â17 million years old. Though life is confirmed only on the Earth, many think that extraterrestrial life is not only plausible, but probable or inevitable.he chemistry leading to life may have begun shortly after the Big Bang, 13.8 billion years ago, during a habitable epoch when the Universe was only 10â17 million years old.

Anatomy is the field of science concerned with the study of the physical structures of an organisms. It's divided into several branches, including histology, embryology, gross anatomy, zootomy, phytotomy, human anatomy, and comparative anatomy.
The study of anatomy involves learning about each part of the body and why it performs in its own specific way. Physicians, surgeons, nurses, and pharmacy technicians must all know and understand anatomy and how the parts of our bodies work together in synergy in order for people to remain healthy.
