Unit 5
Respiration, Internal Environment, Coordination and Gene Technology
What this unit covers
Study respiration and movement, then homeostasis, nervous coordination and gene technology. The unit links cellular energy with whole-organism responses and molecular applications.
- Explain how cells release and use energy.
- Describe control of internal conditions and responses.
- Evaluate uses and limits of gene technology.
