Text Solution

Verified by Experts

(i) Biological studies are impossible without a mocroscope designed using physics principles.
(ii) The invention of the electron micorscope has made it possible to see even the structure of a cell. X-ray and neutron diffraction techniques have helped us to understand the structure of nucleic acids, which help to control vital life processes.X-rays are used for diagnostic purposes.
(iii) Radio-isotopes are used in radiotherapy for the cure of cancer and other diseases. In recent years, biological processes are being studied from the physics point of view.
