Biology EOC Test Day Review Insights

This video tutorial covers key biology concepts for an EOC review. It begins with the characteristics of living organisms, explaining why viruses are not considered living. The four biomolecules essential to life are discussed, followed by an overview of cell types and the cell cycle, including mitosis and meiosis. The structure and function of DNA, along with the impact of mutations, are explained. The video also covers genetics, evolution, and classification, highlighting natural selection and evidence for evolution. Ecological succession and symbiotic relationships are explored, and the tutorial concludes with test-taking strategies to help students succeed.
