Topics inside Biology
From ecosystems and body systems to inheritance and natural selection, Biology explains how life is organized and how it adapts.
- Ecology: food webs, populations, and biomes

- Scientific skills: interpreting diagrams and simple data
Quick facts
Humans share about 99.9% of their DNA with each other, yet small differences can affect traits. Many organisms rely on symbiosis - close partnerships that can benefit one or both species.
