Study Notes
What is Biology?
- Biology is the scientific study of life or living things.
- It involves recognizing life by common characteristics shared by living systems.
Characteristics of Living Things
- Composed of one or more cells
- Complex and highly ordered
- Can respond to stimuli, grow, reproduce, etc.
- Transmit genetic information to their offspring
- Need energy to accomplish work
- Maintain relatively constant internal conditions (homeostasis)
- Capable of evolutionary adaptation to the environment
The Scientific Study of Biology
- Involves asking questions, suggesting possible answers, and testing for validity through experimentation
- Uses a scientific method that follows the study of structures and processes that can be verified, observed, and measured
Relationships with Other Fields of Natural Sciences
- Biology merges information and tools from all natural sciences
- Examples include chemistry (naturally occurring elements, chemical bonding, molecules, acids, bases) and physics (conversion of radiant energy into organic molecules by photosynthesis)
Importance of Studying Biology
- Helps understand how living things work, function, and interact with the environment
- Has many applications in everyday life, such as:
- Development of drugs to treat human diseases
- Understanding how animals and plants function
- Ecological studies to evaluate environmental issues
- Forensic biology to investigate crimes
- Applications in medicine, agriculture, food processing, and more
Applications of Biology
- Fermentation used in wine-making, brewing, baking bread, and producing cheese
- Antibiotics produced by mould fungi or bacteria
- Production of industrial chemicals (e.g., citric acid, lactic acid) using bacteria or fungi
- Sewage disposal dependent on bacteria in filter beds
