What does the term "biophysics" refer to?

The term "biophysics" specifically refers to the intersection of biology and physics, where principles and concepts from physics are applied to understand biological systems. This utilization of physics can encompass various areas, including molecular dynamics, the mechanics of biological structures, and the energetics of cellular processes. By leveraging the quantitative nature of physics, biophysics provides insights into how biological systems operate at the molecular and cellular levels, making it crucial for advancements in fields like medical research, drug design, and genetic engineering. Thus, the correct choice accurately captures the essence of biophysics as a scientific discipline that bridges these two domains to explore and explain the physical mechanisms underlying biological functions.
