Biology is the study of life and living organisms.
It encompasses various fields including genetics, ecology, and physiology.
The goal of biology is to understand the processes that occur in living organisms and how they interact with each other and their environment.

Organization: Living things are organized into cells, tissues, organs, and systems.
- Cells are the basic unit of life.
- Organisms can be unicellular (single-celled like bacteria) or multicellular (composed of many cells like humans).
Metabolism: Living organisms carry out chemical reactions to maintain life.
- Includes catabolism (breaking down molecules) and anabolism (building up molecules).
Homeostasis: Ability to maintain a stable internal environment despite external changes.
- Examples include temperature regulation and pH balance.
Growth and Development: Organisms grow and develop following specific instructions coded in their DNA.
Reproduction: The ability to produce new organisms.
- Can be sexual (involves two parents) or asexual (single parent).
Response to Stimuli: Living things can respond to environmental changes.
- This includes movement towards or away from stimuli.
Evolution: Living organisms undergo changes over time, which can lead to adaptations that suit them to their environments.
- Supported by the theory of natural selection.

Understanding biology helps us make informed decisions related to health, conservation, and environmental impact.
Biologists contribute to advancements in medicine, agriculture, and biotechnology.
