Answer:
systems (system biology)
Explanation:
Systems biology can be defined as a methodology whose interest is to understand the high scale levels of complexity in biology (i.e. organism level, tissue level, cell function, etc) by integrating information/data from different sources, and thus examine the interaction between biological components. This approach is contrary to reductionism, which is another approach used in biology research. Therefore, systems biology is a holistic approach aimed at modeling complex biology systems by applying computational and mathematical methods, enabling to understand biological systems.
