Natural Selection: unequal reproductive Success leads to evolution of adapt in populations Inferences "Survival of the fittest" 1.10 Evolution is connected to our everyday lives: □ Artificial Selection 8 #cladogram 1.11 Theme : Life depends on the flow of information : C-G₁₂ □ Process of life all depends on the transmission and Cell T-A use of information. •DNA - blueprint for proteins (ALL cells have DNA) o Geres Nucleus DNA 1.12 Theme: Structure and function are related : The relationship between structure and function can be observed at every level of life. Ex: Molecular level, the structure of a protein. correlates with its function. - hemoglobin molecules transport 0² in blood Ex: Cellular level, the long extensions of nerve cells. enable them to transmit impulses from your Spinal cord to your toes. > TO D Cells are the structural and functional units of life: OA CELLS enclosed by membrane • use DNA in genetic info • use ribosomes to assemble protiens. 2 forms of Cells: . (1. Prokaryotic)- small, simple cells that lack a frue nucleus or membrane bound Organelles. Ex: All bacteria Contain SUNG 2. Eukaryotic - larger and more complex, contain a true nucleus and membrane bound organelles. Ex: plants, animals, protists and Fungi 1.13 Theme: Life depends on the transfer and transformation of energy and matter 8 a matter (anything that takes of space) - recycled through. Energy goes in one direction. ecosystem A Producers and Consumers. ↳ consum food 40 Photosynthesis DProduceerplants, Algia. •makes its own. food Autotroph. □ Consumer -> humans, animals • consum food for energy -> Herotroph
