Compare and contrast human organ systems with those of other species. Describe the structure and function of major organs in human systems. Identify the causes and effects of diseases, explain their transmission,and identify prevention strategies. Describe how body systems work together. Use models to compare and contrast the structure and function of the circulatory system with the structure and function of the skeletal system.
Fossils show past life, extinct species,and environmental changes over time.
Organisms change and new species may arise due to genetically coded adaptations. Describe how fossils can be used by scientists to trace the history of a species. Explain how scientists use fossils to prove that life forms, climate,environment, and geologic features in a certain location are not the same now as they were in the past. Provide examples of the concept of natural and artificial selection and its role in species changes over time. Compare how sexually and asexually reproducing species transfer genetic information to offspring.
