Classifying Organisms and Dichotomous Keys

Explain cells as the basic unit of life, describe hierarchical biological organization, and model how specialized cells like neurons transmit signals.

Examine digestive organs and dentition in processing food, and investigate biomechanical forces acting on the skeletal system.

Classify plants, animals, and microorganisms using structural traits and build dichotomous keys to identify diverse species.

Construct and interpret food chains and food webs to trace the movement of energy and nutrient cycling across habitats.

Analyze structural and behavioral adaptations such as camouflage and mimicry, and evaluate ecosystem responses to environmental shifts.

Evaluate personal and community health factors including microbial roles, exercise physiology, substance risks, and body respect.
