Document Summary

Living things exhibit order pattern: pattern of veins in a butterfly, patterns in the shell of a mollusc. Possess energy: require energy inputs to stay alive, ex plant energy = solar energy, converted to chemical energy, some lost as heat. Responds to environment/stimuli: adjust behaviour, function, structure etc, amoeba move closer to something that it finds attractive. Contains dna: allow for information to be carried forward, units of inheritance. Doesn"t just respond to environment, regulate internal environment conditions to environment: salt water fish takes in salt and expels salt. Regulate internal conditions: temperature of their bodies. Populations of living organisms adapt and evolve. Change over time: make adaptations essential to growth/survival. Ex, plants with the ability to retain water. Individuals with characteristics favourable in the environment survive. These organisms reproduce and pass on these adaptations. A population produces more offspring than can survive. Suitable trains will become more and more common in the population.
