1 What is life science Chien-Ming Li MD, PhD

2 Life science Study of living things Structure: atom, molecule, macromolecule, organelle, cell, tissue, organ, system Function: metabolism Behavior Evolution

3 All living things 1.Are composed of cells 2.require energy 3.Reproduce 4.Display heredity 5.Respond to stimuli 6.Remain homeostasis 7.Adapt 8.Evolve

4 Living things remain homeostasis Internal balance Within a normal range Feedback Stimulus  receptor  integrator  effector  reresponse

5 Living things adapt and evolve For survival Physical adaptation – Changing color to match environment Behavioral adaptation – Hibernation – Migration Evolution: common ancestor – the process by which one species gives rise to another
