Zoology is the study of how animals interact with their environment. The study of the Animal Kingdom, including its architecture, evolution, embryology, habits, taxonomy, and distribution of both living and extinct animals, is the topic of this most fascinating branch of biology. During studying for the exam, it is suggested that students concentrate more on subjects like human physiology and reproduction. A list of subjects significant from an exam perspective is provided below:
