Answer 1

Explanation:

1. Science is what we do to find out about the natural world. Natural sciences include physics, chemistry, biology, geology and astronomy. Science uses mathematics and logic, which are sometimes called "formal sciences". 'Science' also refers to the large amount of knowledge that has been found using this process.
2. Biochemistry is the study of the chemical substances and vital processes occurring in live organisms. Biochemists focus heavily on the role, function, and structure of biomolecules. The study of the chemistry behind biological processes and the synthesis of biologically active molecules are examples of biochemistry.
3. Nuclear reactions differ from ordinary chemical reactions
4. Atomic numbers of nuclei may change (elements are converted to other elements or an element can be converted to an isotope of that element). Protons, neutrons, electrons and other elementary particles may be involved in a nuclear reaction.
5. Polymers are defined as high molecular mass macromolecules which consist of repeating structural units derived from the appropriate monomers. The unit molecules that combine with each other to to form a polymer is called a monomer. The process of formation of polymers from respective monomers is called polymerisation.
6. Energy is the capacity of a physical system to perform work. Energy exists in several forms such as heat , kinetic or mechanical energy, light, potential energy , electrical, or other forms. Energy is the ability to do work. Energy sources could be classified as Renewable and Non-renewable.
