| Question | Answer |
|---|---|
| What is biology? | The study of life. |
| What types of topics fall under the study of biology? | Diversity of life, disease, technologies, improve agriculture, preserving the enviornment. |
| Explain the scientific method. | A series of problem solving procedures that might include observations, forming a hypothesis. |
| What are the benefits of studying biology? | Learning about the enviornment. |
| What is mutualism? | When both organisms benefit. |
| What is commensalism? | one organism benfits and the other is not affected. |
