<Biology> studies living systems: how <biological cells> maintain themselves, how <organisms> develop and reproduce, and how <evolution> generates diversity. Its scales connect <molecules>, <genes>, <biological cells>, <organisms> and the interactions studied by <ecology>. These are complementary viewpoints: a <protein>'s chemistry can explain a cellular mechanism, while <evolution> explains why inherited variants of that mechanism persist. See https://openstax.org/books/biology-2e/pages/1-1-the-science-of-biology[Clark, Douglas and Choi, Biology 2e: the science of biology].

Two organizing ideas make this immense subject navigable: shared cellular organization and descent with inherited modification. A <neuron> and a <gliding bacterium> differ dramatically in shape and behavior, yet both depend on a <cell membrane> and <metabolism>. Their differences become intelligible through specialization and <evolution>.

Keep observations separate from the <mathematical models> used to explain them. A measured <membrane potential> is evidence; an idealized <two-state ion-channel gating> equation proposes a mechanism. A <mathematical model> earns trust through predictions and comparisons with measurements. Its assumptions delimit its usefulness, and disagreement can reveal missing biology rather than a faulty measurement.
