What a finished product looks like

This is a model of the work you should turn in today. Use it to check your own: match the structure and the level of detail, do not copy it. Your data and wording should be your own.

Worked CER on a parallel case (fingerprint comparison, not today's tissue prompt)
Completes: A claim-evidence-reasoning paragraph modeling how a forensic examiner argues an identification from comparison to a reference, so students can copy the CER structure and depth without it answering today's histology question.

Claim: The latent print lifted from the scene could indicate that this individual touched the surface before the incident.\nEvidence: Compared to a known reference print taken directly from the individual, the latent print showed the same pattern of ridge endings and bifurcations in the same relative positions, which are the features examiners use to match prints.\nReasoning: Identification is based on agreement between an unknown sample and a known reference, so the side-by-side comparison is what makes the matching ridge features meaningful. A shared arrangement of ridge endings and bifurcations is consistent with both prints coming from the same finger.\nLimitation: A partial or smudged latent print cannot confirm identity on its own; it must be combined with the quality of the reference print, the number of matching features, and other case evidence before a firm conclusion is reached.

Also due today: Upload your CER and annotated notebook page to the tracker by end of class.

WebXam problem for today's skill

One exam-style question that uses exactly what you practiced today. Try it before you reveal the answer, then read why each choice is right or wrong.

WebXam-style domain: Biotechnology Research and ExperimentsSelf-check skill: Interpreting histology by comparison to normal reference tissue
A pathology student says a tissue slide looks abnormal but has no normal reference image to compare it to. Why does this weaken the interpretation?
