Document Summary
Cell into organism: nerve cell work? o o. Hypotheses answers to scientific questions: why do leaves turn colours in the fall? o o. Cells transform energy from one form to another to do work. Relies on sunlight, captured in chemical energy. Cells need energy to do work, ex. o. Nothing makes energy, they just transfer it. Domino anecdote-nothing will happen w/o reception: mutations+disease. Inspired humans to model tech from nature (biomimicry) o. Robots that can walk on walls (gecko: develop spider silk. Information processing- detected with structure, processed for function. Dna (transcription) -> rna (translation) -> protein. Distinct genomes in typical human cell- 2: nuclear genome (nucleus, mitochondrial genome. Distinct genomes in typical plant leaf cell- 3 o. Charles darwin + theory of natural selection o. Environment selects for beneficial changes (heritable: not a random process, natural selection. Hypothesis= tentative answer to well framed question. Theory= strong, well supported, expanded, correctable o o.
