Explanation:

Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments. The various field of science include the following;

1. Serology: the study of blood.

2. Bioinformatics: the development of digital storage and technology for use in bioscience applications.

3. Toxicology: the study of poisons.

4. Biotechnology: the study and use of biological structures and processes for industrial purposes.

5. Genetics: the scientific study of heredity.

6. Epigenomics: the study of the effects and interaction of the expression of genes.

7. Biochemistry: the study of the chemistry of organisms.

8. Taphonomy: the study of decomposition of bodies after death.
