## Notes

- **Cells and Systems**: Living things function as balanced systems, from single cells to complex organisms. [Topic](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17317)
- **Organisms**: Diverse living things share common functions met by different structures, e.g. food gathering. [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17319), [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17319)
- **System Concept**: Applying the idea of system to describe an organism's general structure and function. [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17319), [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17319)
- **Cell**: The basic unit of life in all living things. [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17320), [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17320)
- **Single vs Multicelled**: Comparing organisms like an amoeba versus a grizzly bear, or an alga versus a poplar tree. [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17320), [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17320)
- **Plant vs Animal Cells**: Distinguished by features such as cell walls versus cell membranes. [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17320), [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17320)
- **Diffusion and Osmosis**: Movement of gases and liquids into and out of cells based on concentration differences. [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17320), [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17320)
- **Tissues and Organs**: Cells contribute to tissues and organs, which build plant and animal structures. [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17320), [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17320)
- **Human Body Systems**: Respiration, circulation, digestion, excretion and sensory awareness systems. [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17321)
- **Organ Roles**: Individual organs such as lungs and bronchia support healthy body function. [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17321)
- **Cell Roles in Body**: Nerve, muscle, blood, skin and bone cells each contribute to healthy body function. [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17321)
- **Response to Stimuli**: Body functions change with conditions, such as heart rate during exercise or reflexes. [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17321)
