Anatomy n the study of the internal and external structure of plants and animals 6

Biochemistry n the study of the chemical processes and products involved in metabolism 7

Botany n the study of plant structure, physiology, distribution and classification 8

Ecology n a study of how living things relate to each other and to their environment 9

Genetics n a study of the structure and function of genes and their transmission from parents to offspring 10

Microbiology n a study of small living things, i. e. micro-organisms 11
