What are the major branches of biology and their focus?

Biology is the scientific study of living organisms and their interactions with the environment. There are many different branches of biology, each with its own focus and area of study. The major branches of biology are as follows:

• Botany: The study of plants, including their structure, growth, reproduction, and metabolism.
• Zoology: The study of animals, including their structure, behavior, and physiology.
• Microbiology: The study of microorganisms, including bacteria, viruses, and fungi, and their effects on other living organisms.
• Ecology: The study of the relationships between organisms and their environment.
• Genetics: The study of heredity and the variation of inherited characteristics in populations.
• Physiology: The study of the functions and processes of living organisms and their parts.
• Evolutionary biology: The study of how living organisms have evolved and adapted over time.
• Biotechnology: The application of biological techniques to the development of new products and processes.

While these are the major branches of biology, there are many sub-disciplines within each branch, and new areas of study are constantly emerging as the field of biology evolves.
