Question:- Are there nuclear reactions going on in our bodies?
Answer:- Yes, there are nuclear reactions constantly occurring in our bodies, but there are very few of them compared to the chemical reactions, and they do not affect our bodies much. All physical objects are made of molecules. A molecule is a series of atoms linked together by chemical (electromagnetic) bonds.
Question:- Describe the relationship between biophysics, physical chemistry, and cell biology.
Answer:- Biophysics is a branch of biological sciences that deals with the study of mechanisms and associated factors that mediate the biomechanics of the living organism. This interdisciplinary field applies the basic principles of physics to understand, interpret and make assumptions about the sub-atomic nature and behavior of the biomolecules. Physical Chemistry is a separate branch of chemical sciences that is concerned with the study of macroscopic chemical systems. The fundamental concepts, theories, and principles in physics are applied to decode the inherent properties of the particulate matter in terms of motion, energy, thermodynamics, electrostatics, time, quantum chemistry, dynamics, light, and chemical equilibria. Cell Biology is a field of biological sciences that is associated with the study of the structure, function, and behavior of the fundamental units of life called cells that is responsible for governing the sustenance of life on earth. All the three disciplines of sciences are interconnected and have a particular relevance on a broad scale such that the early concepts and findings of biophysics and physical chemistry serve as the foundational core for the betterment of life-science research oriented to deciphering the secrets and modeling of these particulate building units of life in terms of disease diagnosis and overcoming global epidemics, improved quality of life, safe and hygienic foods, preserving biodiversity and sustainable development.

Answer:- Option A
Question:- What is the scientific name for washing soda?
Answer:- Sodium carbonate (also known as washing soda or soda ash), Na2CO3 is a sodium salt of carbonic acid.
Question:- Scientific name for baking soda?
Answer:- Sodium bicarbonate or sodium hydrogen carbonate is the chemical compound with the formula NaHCO3. Sodium bicarbonate is a white solid that is crystalline but often appears as a fine powder. Since it has long been known and is widely used, the salt has many related names such as baking soda, bread soda, cooking soda, and bicarbonate of soda.
