Diffusion, osmosis and active transport in Unit 1 — Biology IAL Past Papers

13 papers, 2016–2024 · Unit 1

The Biology IAL Unit 1 — Molecules, Diet, Transport and Health past papers in the collection that assess diffusion, osmosis and active transport.

By unit: all units (28) · Unit 1 (13) · Unit 2 (1) · Unit 3 (2) · Unit 4 (4) · Unit 5 (7) · Unit 6 (1)

These papers were matched to diffusion, osmosis and active transport automatically, by keyword patterns in their questions and mark schemes. A hand-check of 65 randomly chosen matches, read against the source question papers, found 53 that genuinely assess the topic and 12 that do not — 81.5% (95% confidence interval 70.4–89.1%). That is a good way to find practice on a topic, not proof a paper covers it, and a paper missing from this list may still assess it. A separate check found real papers that assess a topic without being tagged for it.
