Development is all the changes that take Development is all the changes that take place during the organism’s lifeplace during the organism’s life
Living things adjust to their environmentLiving things adjust to their environment Air, water, temperature, other organismsAir, water, temperature, other organisms StimulusStimulus: anything in an organisms : anything in an organisms

HomeostasisHomeostasis is regulation of an is regulation of an organism’s internal environment to organism’s internal environment to maintain conditions suitable for survivalmaintain conditions suitable for survival
Living Things Adapt and EvolveLiving Things Adapt and Evolve
Adaptations Adaptations Any Any inheritedinherited structure, behavior, or internal structure, behavior, or internal
process that enables an organism to repond process that enables an organism to repond to environmental factors and live to produce to environmental factors and live to produce offspring offspring
The gradual change in a species through The gradual change in a species through adaptations over time is adaptations over time is evolutionevolution
The theory of evolution can help answer The theory of evolution can help answer many of the questions people have about many of the questions people have about living thingsliving things
