Biophysics deals with biological functions that depend on physical agents such as electricity or mechanical force, with the interaction of living organisms with physical agents such as light, sound, or ionizing radiation, and with interactions between living things and their environment as in locomotion, navigation, .
You can't say for certain that one is more difficult than the other, but if you know what kind of student you are, then the choice may be clear.
If you're the kind of student that has always done well regardless of the subject, the broad interdisciplinary nature of biophysics mightn't faze you..
Biophysics is the study of physical phenomena and physical processes in living things, on scales spanning molecules, cells, tissues and organisms.
Biophysicists use the principles and methods of physics to understand biological systems.
It is an interdisciplinary science, closely related to quantitative and systems biology.
The journal publishes papers in the field of biophysics, which is defined as the study of biological phenomena by using physical methods and concepts.
Original papers, reviews and Biophysics letters are published.
