Document Summary
5 unifying themes: organization, energy and matter. Levels of biological organization: molecule, organelle, cell, tissue, organ/organ system, organism, population, community, ecosystem, biosphere. Emergent properties: characterize nonbiological entities, small complex parts make up bigger picture. Systems biology: exploration of biological systems by analyzing the interactions among its parts. *the cell is the lowest level of organization that can perform all activities needed for life* Membrane bound organelles and nucleus no nucleus or membrane bound organelles. Made up of nucleotides (a,g,c,t)- specific sequences of nucleotides encode for genes. Protein synthesis=dna (transcription) rna (translation) amino acid chain (protein folding) protein. Genome: an organism"s entire set of genetic instructions. There is always a flow of energy. Sun to producers to consumers, so there is a nutrient cycle: energy= capacity to do work, every organism interacts with its environment. Negative feedback- the response reduces the initial stimulus.
