## Notes

- **Cells and Systems**: Living things are organized as systems, from cells to organs, that carry out life functions ([Topic](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17317)). [Topic](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17317)

- **Tissues and Organs**: Cells contribute to tissues and organs in 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), [Topic](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17317)).
