Ecology and Environmental Protection Keep a small glossary in the back of your notebook

This is often the most challenging yet fascinating part of the year. Students learn about DNA, genes, and chromosomes. You’ll explore how traits are passed from parents to offspring, the basics of Mendelian genetics (dominant and recessive traits), and the role of mutations. 2. Evolution and Adaptation

In an era of climate change, this unit is vital. It covers ecosystems, food chains, energy flow, and the impact of human activity on the biosphere. Students learn about biodiversity and the importance of sustainable development. How to Study Effectively from the Textbook

Building on genetics, the textbook covers how species change over time. You’ll study Charles Darwin’s theory of natural selection, the evidence found in the fossil record, and how animals and plants adapt to survive in specific environments. 3. Human Health and Disease
