## Answer key

1. **B.** Cells are the basic unit of life, and living things are made up of one or more cells that carry out life processes ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17320)).

2. **Sample answer: Lungs exchange oxygen and carbon dioxide between the air and the blood.** Oxygen moves into the blood while carbon dioxide moves out and is exhaled, supporting the body's need for oxygen and removal of waste gas ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17321)).

3. **True.** Diffusion moves gases and liquids into and out of cells according to concentration differences, moving from areas of higher concentration to lower concentration ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17320)).

4. **112 beats per minute.** 70 × 0.60 = 42, and 70 + 42 = 112, showing how heart rate rises in response to exercise ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17321)).

5. **B.** Plant cells have a rigid cell wall in addition to a cell membrane, while animal cells have only a cell membrane ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17320)).

6. **Sample answer: The development of vaccines through research into how immune cells respond to disease has reduced illness and death from infectious diseases.** Research into cells and body systems has led to medicines, immunization procedures and diets suited to organ health ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17322)).
