A panoramic scientific illustration merging all key biology topics for grades 11-12 into one continuous ecosystem scene, ultra-realistic style: In the foreground, a neuron (neurobiology) synapses with a leaf's vascular system (applied biology). The leaf undergoes photosynthesis (energy conversion) while revealing microscopic views of chloroplasts and mitochondria. Its DNA strands (molecular genetics) morph into a phylogenetic tree (evolution) that forms the landscape. In the background, a balanced ecosystem (ecology) shows predator-prey dynamics and nutrient cycling. All elements flow together organically through biological connections - no artificial borders, labels, or sections. Color palette: natural greens/blues with molecular structures in accurate scientific colors (red ATP, blue DNA). Style: National Geographic scientific realism with macro-to-micro transitions.emoji
