* their metabolism.

2: Biophysics: It is a branch of biology that deals with the study of  laws and and techniques of physics to explain:
* the metabolism of living organism.
* to find out the age of fossils.

3: Radio Physics: It is the sub-branch of bophysics where radioisotopes are used to trace the translocation of different material "in vivo" within the living organism.
