Document Summary

What is biology: the study of life. Internal sodium chlorides: regulate internal conditions, temperature of their bodies. How does a biologist define life: populations of living organisms adapt and evolve, change over time, make adaptations essential to growth/survival, ex, plants with the ability to retain water, millions of years of evolution. Individuals with characteristics favourable in the environment survive: these organisms reproduce and pass on these adaptations. Suitable trains will become more and more common in the population. Skin surface: function: resist abrasion, form: multilayered regenerates rapidly, function is to protect so form is thick and layered. This is because the form fits the function. Evolution directly observed on short time scales: artificial selection: pesticide/antibiotic resistance, ex, soapberry bug - beaks to access fluids, the ones in areas that have larger fruits have larger beaks, there are experiments which show changes over time.
