Biological System
A biological system is a complex network of biological components that work together to perform specific functions. These components can include molecules, cells, tissues, organs, and organisms. Understanding biological systems is essential in fields such as biology, medicine, and biotechnology.
Key Concepts
- Organization: Biological systems are organized at multiple levels, from the molecular to the organismal level.
- Homeostasis: Biological systems maintain internal stability through processes such as temperature regulation, pH balance, and nutrient levels.
- Interactions: Components within biological systems interact with each other to carry out specific functions, such as signal transduction and metabolic pathways.
- Emergent Properties: Biological systems exhibit properties that arise from the interactions of their components, such as the behavior of a whole organism that cannot be predicted from the behavior of individual cells.
- Feedback Mechanisms: Biological systems utilize feedback loops to regulate and maintain physiological processes.
Study Guide
When studying biological systems, it's important to focus on the following areas:
- Cell Biology: Understand the structure and function of cells, as well as the various organelles and molecules within cells.
- Physiology: Learn about the physiological processes that occur within organisms, including digestion, respiration, circulation, and excretion.
- Genetics: Explore the principles of inheritance, gene expression, and the role of DNA in biological systems.
- Ecology: Consider the interactions between organisms and their environment, including topics such as population dynamics, food webs, and energy flow.
- Systems Biology: Gain an understanding of how biological systems are studied and modeled using computational and mathematical approaches.
Further Exploration
To deepen your understanding of biological systems, consider exploring topics such as biochemistry, evolutionary biology, immunology, and neurobiology. Additionally, staying updated on current research and advancements in the field can provide valuable insights into the complexities of biological systems.

PHYSICAL SCIENCE (NGSS)
Matter and Its Interactions
Students who demonstrate understanding can:
Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.
Energy
Students who demonstrate understanding can:
Create a computational model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known.
Plan and conduct an investigation to provide evidence that the transfer of thermal energy when two components of different temperature are combined within a closed system results in a more uniform energy distribution among the components in the system (second law of thermodynamics).
