Read Inhalation
This SOF ISO pattern tests identify changes during inhalation. Read the condition carefully, then use the method below before you solve.
Living-system questions are solved by matching a structure or organism to its function, process and stated condition.
Gas exchange means oxygen in, carbon dioxide out
Oxygen in, carbon dioxide out, across the respiratory surface
Name the respiratory surface first, then trace oxygen to it and carbon dioxide away from it. Different organisms use different surfaces.
Find the tested idea
Write down the quantities, directions or conditions given in the stem before selecting a formula or rule.
Work from the evidence
Use one governing relationship at a time. For a visual question, trace the path; for a numerical question, keep units and signs consistent.
Verify before choosing
Use the wording, diagram and units exactly as given. Select an option only after it satisfies every stated condition.
